Description

Technical Field

[0001] The invention relates to the technical field of bathroom facilities, and in particular to a pressurized descaling shower head. Background Art

[0002] The showerhead discharges water through the water outlet hole on the water outlet panel. The diameter of the water outlet hole of most showerheads is fixed. When the water pressure changes, the jet force of the water sprayed from the water outlet hole changes. Especially when the water pressure is very low, the jet force is weak, resulting in incomplete shower cleaning and a long shower time. In addition, since there are often impurities such as mud and sand in the water pipes, after the showerhead has been used for a long time, the impurities gather at the water outlet hole, which then blocks the water outlet hole, causing the water to be obliquely sprayed or even completely blocked without water, and the user's shower experience is poor.

[0003] In some existing showers, descaling is achieved by setting a lever. One end of the lever is connected to the first transmission column. The first transmission column makes the lever swing under the action of water pressure. The other end of the lever is connected to the descaling needle plate through the second transmission column to drive the descaling needle plate to move to achieve pressurization and descaling. This solution has the following defects: in order to achieve the movement of the lever, the lever needs to be used in conjunction with the first transmission column and the second transmission column, and the first transmission column and the second transmission column need to be movably connected to the lever respectively, resulting in the setting of the lever making the structure of the entire shower more complicated, with more parts and complicated manufacturing processes, resulting in cumbersome assembly processes of the shower, long production cycles, and high costs.

[0051] Moreover, when the descaling needle penetrates the first water outlet hole to remove scale, there is a water outlet gap between the descaling needle and the inner wall of the first water outlet hole, so that the water flow passed into the water inlet hole can smoothly pass through the water outlet gap and discharge water. Compared with the method of directly discharging water through the first water outlet hole without the descaling needle, discharging water through the water outlet gap between the descaling needle and the inner wall of the first water outlet hole can reduce the water outlet area, increase the water outlet pressure, ensure that the water outlet has a certain strength, and improve the user's shower experience.

[0052] The descaling and pressurizing functions can be achieved by only pushing the descaling needle plate through the driving component in the pressurized descaling shower head, which can reduce the number of parts of the shower head, simplify the structure of the shower head, improve the production efficiency of the shower head and reduce the production cost. At the same time, since the shower head drives the descaling needle to move toward the outside of the shower head and push out the first water outlet to descaling and achieve pressurized water discharge when water enters, the dirt remaining on the descaling needle and the inner wall of the first water outlet can be washed away by the high-pressure water flow, and the descaling is more thorough, ensuring that there is no residual dirt after the user uses the shower head.

[0098] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0099] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0100] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0101] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0102] In this embodiment, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0103] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0104] like Figure 1 and Figure 2 As shown, this embodiment provides a pressurized descaling shower head, which can achieve descaling and pressurization functions when water is entering.

[0105] Specifically, combined Figure 1 , Figure 3 , Figure 4 as well as Figure 5 The pressurized descaling shower head comprises a water outlet assembly 1, a descaling needle plate 2 and a driving assembly 3. The descaling needle plate 2 and the driving assembly 3 are both installed on the water outlet assembly 1.

[0106] The water outlet assembly 1 is provided with a water inlet hole 161 (see Fig.10) and the first water outlet hole 1321, water can enter the water outlet assembly 1 through the water inlet hole 161, and finally flow out through the first water outlet hole 1321. The descaling needle plate 2 includes a movable plate 21, and descaling needles 22 and a first push portion 23 arranged on both sides of the movable plate 21. The movable plate 21 is arranged in the water outlet assembly 1 so as to be reciprocatingly movable between a first position and a second position. When the movable plate 21 is in the second position, the distance between the movable plate 21 and the first water outlet hole 1321 is greater than the distance between the movable plate 21 and the first water outlet hole 1321 when the movable plate 21 is in the first position. When the movable plate 21 is in the first position, the descaling needle 22 penetrates the first water outlet hole 1321 and there is a water outlet gap between the inner wall of the first water outlet hole 1321. That is, the movable plate 21 in the second position is lifted relative to the first water outlet hole 1321, and the descaling needle 22 does not penetrate the first water outlet hole 1321. It is understandable that when the movable plate 21 is in the second position, the descaling needle 22 may be completely separated from the first water outlet 1321 , or the top portion may extend into the first water outlet 1321 but not pass through the first water outlet 1321 .

[0107] Optionally, a plurality of descaling needles 22 and first water outlet holes 1321 are provided in a one-to-one correspondence, to ensure that each first water outlet hole 1321 can be effectively cleaned and that the water outlet force of the plurality of first water outlet holes 1321 is uniform.

[0108] It should be noted that, when there is no dirt in the first water outlet 1321 or there is less dirt attached to the inner wall, when the movable plate 21 of the descaling needle plate 2 moves to the first position, the water flows out through the gap between the descaling needle 22 and the first water outlet 1321 or through the gap between the descaling needle 22 and the dirt. When the dirt attached to the inner wall of the first water outlet 1321 reaches a certain amount to cause the internal space of the first water outlet 1321 to be significantly reduced, in the process of the movable plate 21 of the descaling needle plate 2 moving to the first position, the gap between the descaling needle 22 and the dirt is zero or interference, so that the dirt is taken out in the process of penetrating the first water outlet 1321. When the dirt is cleaned, the water can flow out through the water outlet gap between the descaling needle 22 and the first water outlet 1321. The driving component 3 is movably arranged downstream of the water inlet 161 so that the driving component 3 can receive the pressure given by the inlet water flow. The driving assembly 3 is provided with a second push portion 321, and the second push portion 321 is slidably abutted against the first push portion 23. The driving assembly 3 is used to move under the pressure of the water flow, and the first push portion 23 is pushed by the second push portion 321 to drive the moving plate 21 to move to the first position. Among them, the moving direction of the driving assembly 3 is different from the moving direction of the moving plate 21. In this embodiment, when the driving assembly 3 moves, the sliding push action between the second push portion 321 and the first push portion 23 can realize the conversion of the movement direction.

[0109] Exemplarily, the moving direction of the driving assembly 3 is parallel to the moving plate 21, and the moving direction of the moving plate 21 is the thickness direction thereof. Further, the central axis of the moving plate 21 coincides with the central axis of the shower, and the moving direction of the moving plate 21 is the central axis direction of the shower.

[0110] The pressurized descaling shower provided by the embodiment of the present application, when the shower enters water through the water inlet hole 161, the water flow pressure can act on the driving assembly 3, so that the driving assembly 3 moves under the action of the water flow pressure, and when the driving assembly 3 moves, it pushes the first push portion 23 through the second push portion 321, and slides along the first push portion 23, so as to drive the moving plate 21 of the descaling needle plate 2 to move from the second position to the first position through the first push portion 23. In this process, the descaling needle 22 on the descaling needle plate 2 penetrates the first water outlet hole 1321 to push out the dirt remaining in the first water outlet hole 1321, so as to realize automatic cleaning of the dirt of the shower under the action of the water flow pressure.

[0111] Moreover, when the descaling needle 22 penetrates the first water outlet hole 1321 to remove scale, there is a water outlet gap between the descaling needle 22 and the inner wall of the first water outlet hole 1321, so that the water flow passed into the water inlet hole 161 can smoothly pass through the water outlet gap and discharge water. Compared with the method of directly discharging water through the first water outlet hole 1321 without the descaling needle 22, discharging water through the water outlet gap between the descaling needle 22 and the inner wall of the first water outlet hole 1321 can reduce the water outlet area, increase the water outlet pressure, ensure that the water outlet has a certain force, and improve the user's shower experience.

[0112] like Figure 6 As shown, it is a schematic diagram of the movable plate 21 of the descaling needle plate 2 being in the second position, at which time the descaling needle 22 has not penetrated the first water outlet hole 1321; Figure 7 , which is a schematic diagram of the movable plate 21 being in the first position, at which time the descaling needle 22 penetrates the first water outlet hole 1321 .

[0113] In the pressurized descaling shower head, the descaling and pressurizing functions can be realized only by pushing the descaling needle plate 2 with the driving component 3, which can reduce the number of parts of the shower head, simplify the structure of the shower head, improve the production efficiency of the shower head and reduce the production cost.

[0114] In the prior art, the pressurized descaling showerhead usually lifts up the descaling needle plate to move away from the first water outlet when water is inletted. When the water is turned off, the descaling needle plate, under the action of a transmission mechanism such as a lever, causes the descaling needle to penetrate the first water outlet to achieve descaling, or the operating part on the showerhead is manually pressed or toggled to drive the descaling needle of the descaling needle plate to penetrate the first water outlet. In both of the above schemes, the showerhead is in a state of no water flow during descaling, and there may be residual dirt on the descaling needle or on the inner wall of the first water outlet after descaling, resulting in incomplete cleaning of the dirt, which can only be flushed away by water flow the next time water is used. If the time interval between the next water use is long, the residual dirt may re-attach to the descaling needle and the inner wall of the first water outlet, making it difficult to flush it clean with water flow.

[0115] However, since the shower head provided in this embodiment drives the descaling needle 22 to move toward the outside of the shower head and push out of the first water outlet hole 1321 when water is entering, so as to descaling and realize pressurized water outlet, that is, descaling and realizing pressurized water outlet at the same time, the dirt remaining on the descaling needle 22 and the inner wall of the first water outlet hole 1321 can be washed away by the high-pressure water flow, and the descaling is more thorough, ensuring that there is no residual dirt after the user uses the shower head. Figure 7 The pressurized descaling shower head also includes a first reset member 4, a first end of which is connected to the water outlet assembly 1, and a second end of the first reset member 4 is connected to the driving assembly 3; the first reset member 4 elastically deforms when the driving assembly 3 moves under the action of water flow pressure to accumulate elastic potential energy. When the water flow pressure disappears, the driving assembly 3 moves and resets under the elastic force of the first reset member 4.

[0116] See also Figure 4 and Figure 5 The pressurized descaling shower head also includes a second reset member 5, a first end of the second reset member 5 is connected to the water outlet assembly 1, and a second end of the second reset member 5 is connected to the descaling needle plate 2; the second reset member 5 is elastically deformed when the moving plate 21 moves to the first position to accumulate elastic potential energy. When the water flow pressure disappears, the driving assembly 3 moves in the opposite direction under the elastic force of the first reset member 4, and no longer pushes the descaling needle plate 2, so that the descaling needle plate 2 moves and resets to the second position under the elastic force of the second reset member 5.

[0117] Exemplarily, the first restoring member 4 and the second restoring member 5 are both springs.

[0118] like Figure 5 , Figure 6 as well as Figure 7As shown, the water outlet assembly 1 is provided with a moving channel 111 and a first opening 112 that passes through the side wall of the moving channel 111, and the driving assembly 3 slides in the moving channel 111 under the action of water flow pressure. The driving assembly 3 includes a connected moving seat 31 and a push member 32. Among them, the moving seat 31 is slidably arranged in the moving channel 111, and has a pressure-bearing surface 310 for contacting with the water flow. The push member 32 can pass through the first opening 112 and be connected and fixed with the moving seat 31, and the push member 32 is provided with the aforementioned second push portion 321, and at least one of the second push portion 321 and the first push portion 23 is penetrated through the first opening 112, so that the two can achieve sliding contact through the first opening 112. When the pressure-bearing surface 310 is driven by the water flow pressure to move the moving seat 31, the moving seat 31 can be guided to prevent it from moving out of position through the sliding cooperation between the moving seat 31 and the moving channel 111. When installing the driving assembly 3 into the moving channel 111 , the moving seat 31 may be placed in the moving channel 111 first, and then the push member 32 may pass through the first opening 112 into the moving channel 111 to connect with the moving seat 31 , thereby reducing the difficulty of installation.

[0119] In this embodiment, see Figure 7 The moving channel 111 includes a first channel 1111 and a second channel 1112 connected to each other, and the first opening 112 penetrates the side wall of the second channel 1112. The water outlet assembly 1 is also provided with a second opening 113, and the water inlet hole 161 is connected to the first channel 1111 through the second opening 113, so that water can flow into the first channel 1111 through the second opening 113. Figure 8 The movable seat 31 includes a first sliding portion 311, a mounting portion 312 and a second sliding portion 313 which are connected in sequence. The first sliding portion 311 is sealed and slidably matched with the inner wall of the first channel 1111, and the end face of the first sliding portion 311 away from the mounting portion 312 is a pressure-bearing surface 310; the mounting portion 312 is used to connect with the push member 32; the second sliding portion 313 is sealed and slidably matched with the inner wall of the second channel 1112. The first sliding portion 311 and the second sliding portion 313 on both sides of the push member 32 are slidably matched with the corresponding channels, which can improve the stability of the movable seat 31 when moving. Since the first sliding portion 311 is in sealed contact with the inner wall of the first channel 1111, when the water flow begins to enter the first channel 1111 through the second opening 113, the water flow can act entirely on the pressure-bearing surface 310, and will not leak through the gap between the first sliding portion 311 and the inner wall of the first channel 1111, so that the water flow can smoothly push the movable seat 31 to move. Since the second sliding part 313 is in sealed sliding contact with the inner wall of the second channel 1112, water can be prevented from flowing through the gap between the two to the side of the second sliding part 313 facing away from the pressure-bearing surface 310, thereby preventing the movement of the movable seat 31 from being blocked.

[0120] In this embodiment, when the inlet water pressure is greater than or equal to 0.1 MPa, the movable seat 31 can be driven to move. The water pressure of municipal water supply to ordinary users' homes is roughly between 0.2 MPa and 0.3 MPa, which is sufficient to meet the water pressure requirement of greater than or equal to 0.1 MPa.

[0121] like Figure 6 , Figure 7 as well as Figure 8 As shown, at least one support column 314 is convexly provided on the pressure-bearing surface 310, and a baffle 18 is provided at one end of the first channel 1111 away from the second channel 1112. When the shower is not in use, the movable seat 31 is kept in a reset state under the elastic force of the first reset member 4, and the support column 314 abuts against the baffle 18, so that a gap H is maintained between the pressure-bearing surface 310 and the baffle 18, and the gap is connected to the second opening 113. When the shower is turned on to allow water to flow into the movable channel 111 through the second opening 113, the water inlet pressure can act on the pressure-bearing surface 310 of the first sliding part 311 due to the existence of the gap, so as to smoothly drive the movable seat 31 to move, and avoid the pressure-bearing surface 310 directly abutting against the baffle 18 under the elastic force of the first reset member 4, so that the movable seat 31 cannot be driven by the water flow. Exemplarily, a plurality of support columns 314 are arranged at intervals to ensure sufficient support strength for the movable seat 31.

[0122] Combination Figure 7 and Fig.13 , a third opening 114 is provided at one end of the second channel 1112 away from the first channel 1111, and the movable seat 31 penetrates into the movable channel 111 through the third opening 114, and a sealing end cover 17 is detachably connected at the third opening 114. Further, the first reset member 4 is arranged between the second sliding portion 313 and the sealing end cover 17. A groove is arranged on the second sliding portion 313, and a fixing column is arranged on the sealing end cover 17. One end section of the first reset member 4 is sleeved on the fixing column, and the other end is penetrated into the groove on the second sliding portion 313. The movable seat 31 and the first reset member 4 are placed in the movable channel 111 through the third opening 114 in sequence, and then the sealing end cover 17 is installed and blocked at the third opening 114. After the installation is completed, the support column 314 can be abutted against the baffle 18 under the elastic force of the first reset member 4.

[0123] For example, see Fig.10 and Fig.13 Two L-shaped locking hooks 119 are arranged at intervals outside the third opening 114, and limiting protrusions are convex on both sides of the outer wall of the sealing end cover 17. After the sealing end cover 17 is sealed at the third opening 114, the sealing end cover 17 is rotated so that the limiting protrusions on both sides thereof are correspondingly inserted into the L-shaped locking hooks 119, so that the locking hooks 119 hook and clamp the sealing end cover 17, thereby realizing the detachable installation of the sealing end cover 17 at the third opening 114.

[0124] See also Figure 7 and Figure 8 The first sliding part 311 is provided with a first sealing groove 3111, and a first sealing ring 33 is provided in the first sealing groove 3111. The first sealing ring 33 is sealed and in sliding contact with the inner wall of the first channel 1111, so as to achieve a sealed sliding fit between the first sliding part 311 and the inner wall of the first channel 1111. The second sliding part 313 is provided with a second sealing groove 3131, and a second sealing ring 34 is provided in the second sealing groove 3131. The second sealing ring 34 is sealed and in sliding contact with the inner wall of the second channel 1112, so as to achieve a sealed sliding fit between the second sliding part 313 and the inner wall of the second channel 1112.

[0125] Exemplarily, the first sealing ring 33 and the second sealing ring 34 are both rubber rings.

[0126] In this embodiment, see Figure 8 and Fig. 9 , the push member 32 also includes a mounting plate 322 and a first buckle 323, and the first buckle 323 and the second push portion 321 are respectively arranged on both sides of the mounting plate 322. A mounting groove 3121 is arranged on the mounting portion 312 of the movable seat 31, and a second buckle 3122 is convexly arranged on the inner wall of the mounting groove 3121, and the first opening 112 allows the mounting plate 322 and the first buckle 323 to pass through. When installing the push member 32, the mounting plate 322 and the first buckle 323 of the push member 32 are made to pass through the first opening 112 into the movable channel 111, and enter the mounting groove 3121 of the movable seat 31, until the first buckle 323 is hooked with the second buckle 3122 on the inner wall of the mounting groove 3121, and at this time, the mounting plate 322 is pressed against the movable seat 31 along the direction in which the first buckle 323 penetrates into the mounting groove 3121. At this time, due to the hook-and-engagement of the first buckle 323 and the second buckle 3122, the push member 32 can be prevented from escaping from the installation slot 3121 through the first opening 112; due to the abutment between the mounting plate 322 and the movable seat 31, the push member 32 can be prevented from continuing to move along the insertion direction (i.e., the direction in which the push member 32 penetrates the installation slot 3121). That is, the mounting plate 322 and the first buckle 323 limit the push member 32 in two opposite directions respectively.

[0127] Specifically, at least one group of first clips 323 are distributed at intervals along the axial direction of the movable seat 31 on the mounting plate 322, and each group includes two first clips 323 arranged at intervals. The two opposite inner walls of the mounting groove 3121 are each provided with a second clip 3122, and the two first clips 323 are hooked one by one on the second clips 3122 on the two opposite inner walls of the mounting groove 3121 to ensure a stable connection and prevent it from falling off.

[0128] See also Fig. 9The first buckle 323 includes a connected cantilever 3231 and a hook 3232. The end of the cantilever 3231 away from the hook 3232 is connected to the mounting plate 322. The second buckle 3122 is provided with a guide slope 31221. When the push member 32 enters the mounting groove 3121, the hooks 3232 of the two first buckles 323 distributed in each group are respectively slidably matched with the guide slopes 31221 on the corresponding second buckles 3122, so that the cantilever 3231 of the two first buckles 323 are deformed by the extrusion force and are gathered toward the middle. When the hook 3232 passes over the second buckle 3122, the cantilever 3231 resumes its deformation, so that the first buckle 323 is hooked on the second buckle 3122.

[0129] In some embodiments, Figure 7 and Figure 8 As shown, one of the first push portion 23 and the second push portion 321 includes a protrusion 3211 protruding toward the other, and the other of the first push portion 23 and the second push portion 321 includes a push surface 231, and the protrusion 3211 is slidably in contact with the push surface 231. The vertical distance between the push surface 231 and the moving plate 21 gradually increases along a preset direction, and the preset direction is the direction in which the driving assembly 3 moves under the action of water flow pressure; the preset direction is different from the moving direction of the moving plate 21.

[0130] Specific to Figure 7 In the embodiment, the preset direction is the left-right direction, and the moving direction of the descaling needle plate 2 is the up-down direction. The second push portion 321 includes the above-mentioned raised portion 3211, and the first push portion 23 includes the above-mentioned push surface 231. The push surface 231 can be an arc surface, an inclined surface, or other forms of curved surfaces, as long as the vertical distance between the push surface 231 and the movable plate 21 gradually increases along the preset direction. When the pressure-bearing surface 310 of the driving assembly 3 moves along the preset direction under the action of the water flow pressure, the raised portion 3211 of the second push portion 321 slides along the push surface 231 to drive the movable plate 21 to move to the first position, so that the descaling needle 22 passes through the first water outlet 1321.

[0131] In this embodiment, a plurality of driving assemblies 3 are provided, and the plurality of driving assemblies 3 jointly drive the descaling needle plate 2 to move under the action of water flow pressure, effectively increasing the driving force. Accordingly, a plurality of first push parts 23 are provided on the moving plate 21 of the descaling needle plate 2, and the plurality of first push parts 23 are matched with the plurality of second push parts 321 of the driving assemblies 3 in a one-to-one correspondence, so as to stably push the descaling needle plate 2 to move.

[0132] More specifically, the plurality of driving components 3 are evenly distributed around the central axis of the shower head in a circumferential manner, so that the driving force exerted on the descaling needle plate 2 is more uniform.

[0133] Exemplarily, the number of the drive components 3 is three, four, or more than four.

[0134] In this embodiment, Figure 4 and Fig.11 As shown, the water outlet assembly 1 includes a water distribution member 11, a water inlet surface cover 12 and a water outlet surface cover 13. The water inlet surface cover 12 and the water outlet surface cover 13 are interlocked and define a first water flow space 14, a first water outlet hole 1321 is provided on the water outlet surface cover 13, a movable plate 21 is movably provided in the first water flow space 14, the water distribution member 11 is provided on the side of the water inlet surface cover 12 facing away from the water outlet surface cover 13, and is provided with the aforementioned movable channel 111, the first opening 112, the second opening 113 and the third opening 114, as shown in FIG. Fig.13 As shown. Combined Figure 3 and Figure 7 , the water inlet cover 12 is provided with a first water hole 121 and a fourth opening 122, the fourth opening 122 is opposite to and connected with the first opening 112, and the first push portion 23 is penetrated in the fourth opening 122 so as to slide and abut with the second push portion 321 penetrated in the first opening 112. The water diversion member 11 is provided with a first water diversion port 115, and the water inlet hole 161 is connected with the moving channel 111 and the first water hole 121 through the first water diversion port 115. The water flow introduced by the first water diversion port 115 enters the flow channel defined between the water diversion member 11 and the water inlet cover 12, and then a part of the water flow enters the moving channel 111 through the second opening 113 and contacts with the pressure-bearing surface 310 to drive the moving seat 31 to move, and the other part enters the first water flow space 14 through the first water hole 121 on the water inlet cover 12, and then is output through the first water outlet 1321.

[0135] Further, see Fig.11 The water outlet surface cover 13 includes a cover plate 131 and a water outlet sleeve 132 which are stacked one on another. The cover plate 131 is provided with a plurality of through holes. The water outlet sleeve 132 includes a rubber pad and a plurality of rubber sleeves provided on the rubber pad. Each rubber sleeve is provided with the aforementioned first water outlet hole 1321. The plurality of rubber sleeves pass through the plurality of through holes on the cover plate 131 in a one-to-one correspondence. The rubber pad is located between the cover plate 131 and the movable plate 21 of the descaling needle plate 2. Of course, in other embodiments, the water outlet sleeve 132 may not be provided, and the first water outlet hole 1321 may be directly provided on the cover plate 131.

[0136] The water distribution member 11 in this embodiment is provided with movement channels having the same number as the driving components 3 , and each driving component 3 slides in the corresponding movement channel 111 .

[0137] In this embodiment, the cooperation between the driving assembly 3 and the descaling needle plate 2 can realize automatic descaling under the action of water flow pressure. In order to improve the descaling flexibility of the shower head, a manual descaling function can also be added. When the dirt is large and the descaling needle 22 cannot penetrate the first water outlet hole 1321 by the water flow pressure, the manual descaling function can be activated to achieve descaling, thereby improving the user experience.

[0138] Specifically, Figure 4 , Fig.10 as well as Fig.11 As shown, the pressurized descaling shower head also includes a descaling button 6, a transmission member 7 and a push plate 8. The descaling button 6 is movably arranged in the water outlet assembly 1, and in this embodiment, it is specifically arranged in the central part of the water outlet assembly 1. The transmission member 7 is movably connected to the descaling button 6; the push plate 8 is movably connected to the transmission member 7, and the push plate 8 is located on the side of the moving plate 21 facing away from the descaling needle 22, and is fixedly connected to the moving plate 21. When the descaling button 6 is manually pressed, the descaling button 6 can be moved relative to the water outlet assembly 1. When the descaling button 6 moves, the push plate 8 is driven to move by the transmission member 7, and then the push plate 8 drives the moving plate 21 to move to the first position, so that the descaling needle 22 passes through the first water outlet hole 1321. When the push plate 8 is driven to move by the descaling button 6. The moving direction of the push plate 8 is the same as that of the descaling needle plate 2 and opposite to that of the descaling button 6. Thus, when the descaling button 6 is inserted into the center of the water outlet cover 13 and is pressed and moved toward the back of the shower head along the axis of the water outlet cover 13, the descaling needle plate 2 can be driven to move toward the water outlet surface of the shower head (i.e., the side of the water outlet cover 13 facing away from the water inlet cover 12) to penetrate the first water outlet hole 1321. Figure 4 In the middle position, when the descaling button 6 is pressed upward, the push plate 8 can be driven to move downward through the transmission member 7 to drive the descaling needle plate 2 to penetrate the first water outlet hole 1321.

[0139] More specifically, the second reset member 5 is arranged between the push plate 8 and the water diverter 11. When the descaling needle plate 2 moves in the direction of penetrating the first water outlet 1321, it compresses the second reset member 5 through the push plate 8. When the water flow pressure disappears or the descaling button 6 is stopped being pressed, the second reset member 5 releases elastic potential energy so that the descaling needle plate 2 is reset under the elastic force of the second reset member 5.

[0140] like Fig.14 , Fig.15 as well as Fig.16 As shown, the descaling button 6 includes a connected pressing portion 61 and a push column 62 protruding from the pressing portion 61 , the pressing portion 61 is used to receive the pressing force of the user, and the push column 62 is movably connected to the transmission member 7 to drive the push plate 8 to move through the transmission member 7 .

[0141] Specifically, the outer wall of the push column 62 of the descaling button 6 is convexly provided with a third push portion 621, and the third push portion 621 is slidably abutted against the transmission member 7, so that the descaling button 6 drives the transmission member 7 to move when it is pressed. The transmission member 7 includes a rotating drum 71 sleeved on the push column 62, a fourth push portion 72 convexly provided on the inner wall of the rotating drum 71, and a fifth push portion 73 convexly provided on the outer wall of the rotating drum 71. The axial direction of the rotating drum 71 is consistent with the moving direction of the descaling button 6, both of which are the axial direction of the water outlet cover 13. The fourth push portion 72 is provided with a first inclined surface 721, and the fifth push portion 73 is provided with a second inclined surface 731, and the first inclined surface 721 and the second inclined surface 731 are both inclined relative to the axial direction of the rotating drum 71. The push plate 8 is provided with a transmission groove 83, and the transmission member 7 is rotatably arranged in the transmission groove 83 around its own axis; the inner wall of the transmission groove 83 is convexly provided with a sixth push portion 84, and the sixth push portion 84 is provided with a third inclined surface 841, and the third inclined surface 841 is inclined relative to the axial direction of the rotating drum 71. The third push portion 621 is slidably abutted against the first inclined surface 721, and the second inclined surface 731 is slidably abutted against the third inclined surface 841, and the second inclined surface 731 is located on the side of the third inclined surface 841 facing away from the moving plate 21.

[0142] When the descaling button 6 is pressed, the descaling button 6 pushes the first inclined surface 721 through the third push portion 621 and slides with the first inclined surface 721 to drive the rotating drum 71 of the transmission member 7 to rotate around its own axis. When the rotating drum 71 rotates around its own axis, the fifth push portion 73 of its outer wall is driven to move synchronously. The fifth push portion 73 pushes the third inclined surface 841 through the second inclined surface 731 and slides with the third inclined surface 841, thereby driving the push plate 8 to move, and the push plate 8 drives the descaling needle plate 2 to move to achieve the descaling pressurization function.

[0143] Further, the push column 62 is uniformly provided with a plurality of third push parts 621 along the circumferential direction, the inner wall of the rotating drum 71 is uniformly provided with a plurality of fourth push parts 72 to form a plurality of first inclined surfaces 721, the outer wall of the rotating drum 71 is uniformly provided with a plurality of fifth push parts 73 to form a plurality of second inclined surfaces 731, and the inner wall of the transmission groove 83 is uniformly provided with a plurality of sixth push parts 84 to form a plurality of third inclined surfaces 841. The plurality of third push parts 621 are slidably abutted and matched with the plurality of first inclined surfaces 721 in a one-to-one correspondence, and the plurality of second inclined surfaces 731 are slidably abutted and matched with the plurality of third inclined surfaces 841 in a one-to-one correspondence, so as to improve the force balance of the transmission member 7 and the push plate 8 during the process of pressing the descaling button 6, and make the transmission process more stable.

[0144] Specifically, see Fig.14 and Fig.15 The push plate 8 includes a plate body 81 and a cylinder body 82 arranged on the plate body 81 . The thickness direction of the plate body 81 is consistent with the axial direction of the cylinder body 82 . The inner hole of the cylinder body 82 is the above-mentioned transmission groove 83 .

[0145] like Figure 4 As shown, a sliding hole 1312 is provided at the center of the cover plate 131 of the water outlet cover 13, and through holes are provided on the water inlet cover 12 and the water diversion member 11, which are directly opposite to and connected to the sliding hole 1312, and the push plate 8 is located on the side of the water diversion member 11 facing away from the water inlet cover 12. The pressing portion 61 of the descaling button 6 is slidably matched with the sliding hole 1312, and the push column 62 passes through the through holes on the water inlet cover 12 and the water diversion member 11 and enters the rotating cylinder 71 in the transmission groove 83. Moreover, the through holes on the water inlet cover 12 and the water diversion member 11 can avoid the cylinder 82 of the push plate 8, so as to avoid interference between the push plate 8 and the two when the push plate 8 moves.

[0146] Further, one of the inner wall of the sliding hole 1312 and the pressing part 61 is provided with a guide protrusion 611, and the other is provided with a slide groove 1313. The guide protrusion 611 can be slidably arranged in the slide groove 1313 to guide the sliding of the pressing part 61 in the sliding hole 1312. Fig.15 The above-mentioned guide protrusion 611 is convexly provided on the outer wall of the pressing portion 61. A plurality of guide protrusions 611 and slide grooves 1313 may be provided in a one-to-one correspondence.

[0147] See also Figure 4 The water outlet assembly 1 is provided with a stopper 1314, which is used to stop the descaling button 6 in the opposite direction of the pressing direction of the descaling button 6 to prevent the descaling button 6 from falling off the water outlet assembly 1. Specifically, the stopper 1314 is provided at one end of the slide groove 1313, and is used to abut against the guide protrusion 611, thereby preventing the guide protrusion 611 from sliding out of the slide groove 1313, and preventing the descaling button 6 from falling off.

[0148] See also Fig.10 and Fig.11 The movable plate 21 is connected with a mounting column 24, which can movably penetrate the water inlet cover 12 and the water diversion member 11, and is connected to the push plate 8 through the first fastener 9, so as to realize the fixed connection between the push plate 8 and the descaling needle plate 2, so that the two can move synchronously. For example, the first fastener 9 is a screw.

[0149] See also Fig.10 , a limit plate 10 is provided on the side of the push plate 8 facing away from the water diversion member 11, and the limit plate 10 is connected to the water diversion member 11, so that the push plate 8 can only move between the limit plate 10 and the water diversion member 11, limiting the movement stroke of the push plate 8. Further, a guide column 85 is provided on one of the limit plate 10 and the push plate 8, and a guide hole 101 is provided on the other. The guide column 85 is penetrated through the guide hole 101 and can be slidably matched with the guide hole 101, thereby guiding the movement of the push plate 8 and preventing the push plate 8 from moving out of position. In this embodiment, at least one guide column 85 is convexly provided on the push plate 8, and a guide hole 101 corresponding to the guide column 85 is provided on the limit plate 10.

[0150] More specifically, see Fig.10 and Fig.12 A first connecting column 1110 is protruding from the water dividing member 11, and the limiting plate 10 is placed on the first connecting column 1110 and is fixedly connected to the first connecting column 1110 through a second fastener 20. Exemplarily, the second fastener 20 is a screw.

[0151] In this embodiment, Figure 1 As shown, the water outlet assembly 1 is further provided with a second water outlet hole 1311, a plurality of first water outlet holes 1321 are arranged around the outer ring of the second water outlet hole 1311, and the water inlet hole 161 is selectively connected with the first water outlet hole 1321 or the second water outlet hole 1311, so that the user can selectively use the first water outlet hole 1321 or the second water outlet hole 1311 to discharge water. Specifically, the second water outlet hole 1311 is directly provided on the cover plate 131.

[0152] See also Fig.12 and Fig.13 The water diversion element 11 is also provided with a second water diversion port 116 and a first flow channel 117 and a second flow channel 118 which are independent of each other.
