Description

Technical Field

[0001] The present invention relates to the technical field of sanitary facilities, and particularly to a pressure - boosting and scale - removing shower head. Background Art

[0002] The shower head discharges water through the water outlet holes on the water outlet panel. The aperture sizes of the water outlet holes of most shower heads are fixed. When the water pressure changes, the jet force of the water ejected from the water outlet holes changes. Especially when the water pressure is very low, the jet force is weak, resulting in incomplete shower cleaning and a long shower time. Moreover, since there are often impurities such as sediment in the water pipeline, after the shower head is used for a long time, the impurities accumulate at the water outlet holes, thus blocking the water outlet holes, causing the water to spray obliquely or even being completely blocked and not discharging water, and the user's shower experience is poor.

[0003] In some existing shower heads, scale removal is achieved by setting a lever. One end of the lever is connected to a first transmission column. Under the action of water pressure, the first transmission column causes the lever to swing. The other end of the lever is connected to a scale - removing needle plate through a second transmission column to drive the scale - removing needle plate to move to achieve pressure boosting and scale removal. This solution has the following defects: To achieve the movement of the lever, the lever needs to be used in cooperation 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. As a result, the setting of the lever makes the internal structure of the entire shower head relatively complex, with more components and complicated manufacturing processes, resulting in a cumbersome assembly process for the shower head, a long production cycle, and a high cost.

[0004] Therefore, there is an urgent need for a new pressure - boosting and scale - removing shower head to solve the above problems existing in the prior art. Summary of the Invention

[0049] Advantages of the present invention:

[0050] For the pressurized descaling shower head provided by the present invention, when water enters through the water inlet hole, the water flow pressure can act on the driving assembly, so that the driving assembly moves under the action of the water flow pressure. When the driving assembly moves, it pushes the first pushing portion through the second pushing portion and slides along the first pushing portion, so as to drive the moving plate of the descaling needle plate to move from the second position to the first position through the first pushing portion. During this process, the descaling needles on the descaling needle plate penetrate through the first water outlet hole to push out the dirt remaining in the first water outlet hole, realizing the automatic cleaning of the dirt on the shower head under the action of the water flow pressure.

[0051] Moreover, when the descaling needle penetrates through the first water outlet hole for descaling, there is a water outlet gap between the descaling needle and the inner wall of the first water outlet hole, so that the water flowing in through the water inlet hole can smoothly flow out through the water outlet gap. Compared with the way of directly flowing out through the first water outlet hole without the descaling needle, flowing out 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 and increase the water outlet pressure, ensuring that the water outlet has a certain strength and improving the user's shower experience.

[0052] In this pressurized descaling shower head, only by pushing the descaling needle plate through the driving assembly can the descaling and pressurizing functions be realized, 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 outwards towards the outside of the shower head to push out the first water outlet hole for descaling and realize pressurized water outlet when water enters, the dirt remaining on the descaling needle and the inner wall of the first water outlet hole can be washed away by the high-pressure water flow, making the descaling more thorough and 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 with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0099] In the description of the present invention, unless otherwise clearly defined 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 integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.

Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0102] The term "and / or" in this embodiment is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present invention generally represents an "or" relationship between the front and rear associated objects.

[0103] In the embodiments of the present invention, the same reference numerals represent the same components, and for the sake of brevity, in different embodiments, the detailed description of the same components is omitted.

[0104] As Figure 1 and Figure 2 shown, this embodiment provides a pressure - increasing and scale - removing shower head, which can achieve the functions of scale removal and pressure increase when water enters.

[0105] Specifically, in combination with Figure 1 , Figure 3 , Figure 4 and Figure 5 , this pressure - increasing and scale - removing shower head includes a water outlet assembly 1, a scale - removing needle plate 2 and a driving assembly 3. The scale - removing 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 Figure 10)(and the first water outlet hole 1321. Water flow 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 moving plate 21, and descaling needles 22 and a first pushing portion 23 respectively arranged on both sides of the moving plate 21. The moving plate 21 is reciprocally movably arranged in the water outlet assembly 1 between a first position and a second position. When the moving plate 21 is in the second position, the distance between the moving plate 21 and the first water outlet hole 1321 is greater than the distance between the moving plate 21 and the first water outlet hole 1321 when the moving plate 21 is in the first position. When the moving plate 21 is in the first position, the descaling needles 22 penetrate through the first water outlet hole 1321 and there is a water outlet gap between the descaling needles 22 and the inner wall of the first water outlet hole 1321. That is, the moving plate 21 in the second position is lifted relative to the first water outlet hole 1321, and the descaling needles 22 do not penetrate through the first water outlet hole 1321. It can be understood that when the moving plate 21 is in the second position, the descaling needles 22 can be in a state of completely disengaging from the first water outlet hole 1321, or in a state where the top part extends into the first water outlet hole 1321 but does not penetrate through the first water outlet hole 1321.)

[0107] Optionally, a plurality of descaling needles 22 and the first water outlet holes 1321 are provided in one-to-one correspondence to ensure that each first water outlet hole 1321 can be effectively cleaned and 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 hole 1321 or there is less dirt attached to the inner wall, when the moving plate 21 of the descaling needle plate 2 moves to the first position, the water flow exits through the gap between the descaling needles 22 and the first water outlet hole 1321 or through the gap between the descaling needles 22 and the dirt. When the dirt attached to the inner wall of the first water outlet hole 1321 reaches a certain amount, resulting in an obvious reduction in the internal space of the first water outlet hole 1321, during the process of the moving plate 21 of the descaling needle plate 2 moving to the first position, the gap between the descaling needles 22 and the dirt is zero or interference, so as to bring out the dirt during the process of penetrating through the first water outlet hole 1321. After the dirt is cleaned, the water flow can exit through the water outlet gap between the descaling needles 22 and the first water outlet hole 1321. The driving assembly 3 is movably arranged downstream of the water inlet hole 161 so that the driving assembly 3 can receive the pressure given by the incoming water flow. The driving assembly 3 is provided with a second pushing portion 321, and the second pushing portion 321 is slidably abutted against the first pushing portion 23. The driving assembly 3 is used to move under the action of the water flow pressure and push the first pushing portion 23 through the second pushing 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, through the sliding pushing action between the second pushing portion 321 and the first pushing portion 23, the conversion of the movement direction can be realized.

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

[0110] In the pressure-increasing and descaling shower head provided by the embodiment of the present application, when water flows into the shower head through the water inlet hole 161, the water flow pressure can act on the driving component 3, so that the driving component 3 moves under the action of the water flow pressure. When the driving component 3 moves, it pushes the first pushing part 23 through the second pushing part 321 and slides along the first pushing part 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 pushing part 23. During this process, the descaling needles 22 on the descaling needle plate 2 penetrate through the first water outlet hole 1321 to push out the dirt remaining in the first water outlet hole 1321, realizing the automatic cleaning of the dirt on the shower head under the action of the water flow pressure.

[0111] Moreover, when the descaling needles 22 penetrate through the first water outlet hole 1321 for descaling, there is a water outlet gap between the descaling needles 22 and the inner wall of the first water outlet hole 1321, so that the water flowing into the water inlet hole 161 can smoothly flow out through the water outlet gap. Compared with the way of directly discharging water through the first water outlet hole 1321 without the descaling needles 22 penetrating, discharging water through the water outlet gap between the descaling needles 22 and the inner wall of the first water outlet hole 1321 can reduce the water outlet area and increase the water outlet pressure, ensuring that the water outlet has a certain strength and improving the user's shower experience.

[0112] As Figure 6 shown, it is a schematic diagram when the moving plate 21 of the descaling needle plate 2 is in the second position. At this time, the descaling needles 22 do not penetrate through the first water outlet hole 1321; as Figure 7 shown, it is a schematic diagram when the moving plate 21 is in the first position. At this time, the descaling needles 22 penetrate through the first water outlet hole 1321.

[0113] In this pressure-increasing and descaling shower head, only by pushing the descaling needle plate 2 through the driving component 3 can the descaling and pressure-increasing functions be realized, 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, for a pressure - increasing and descaling shower head, usually when water enters, the descaling needle plate is lifted and moves away from the first water outlet hole. When the water is turned off, under the action of a transmission mechanism such as a lever, the descaling needle penetrates the first water outlet hole to achieve descaling, or manually presses or toggles an operating member on the shower head to drive the descaling needle of the descaling needle plate to penetrate the first water outlet hole. In both of the above - mentioned schemes, the shower head is in a state without water flow during descaling, and after descaling, there may be residual dirt on the descaling needle or on the inner wall of the first water outlet hole, resulting in incomplete dirt cleaning. It can only be washed away by water flow during the next water use. If the time interval between the next water use is relatively long, the residual dirt may re - adhere to the descaling needle and the inner wall of the first water outlet hole, making it difficult for the water flow to wash it clean.

[0115] However, since the shower head provided in this embodiment drives the descaling needle 22 to move out of the first water outlet hole 1321 in the direction of the outside of the shower head to remove scale and achieve pressure - increasing water output when water enters, that is, it achieves pressure - increasing water output while removing scale, it can make the dirt remaining on the descaling needle 22 and the inner wall of the first water outlet hole 1321 be washed away by high - pressure water flow, making the descaling more thorough and ensuring that there is no residual dirt after the user finishes using the shower head. Further, referring to Figure 7 The pressure - increasing and descaling shower head further includes a first reset member 4. The first end of the first reset member 4 is connected to the water outlet assembly 1, and the 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 store elastic potential energy. When the action of water flow pressure disappears, the driving assembly 3 moves and resets under the elastic force of the first reset member 4.

[0116] Referring to Figure 4 and Figure 5 The pressure - increasing and descaling shower head further includes a second reset member 5. The first end of the second reset member 5 is connected to the water outlet assembly 1, and the second end of the second reset member 5 is connected to the descaling needle plate 2; the second reset member 5 elastically deforms when the moving plate 21 moves to the first position to store elastic potential energy. When the action of water flow pressure disappears, the driving assembly 3 moves in the reverse direction under the elastic force of the first reset member 4 and no longer pushes against 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, both the first reset member 4 and the second reset member 5 are springs.

[0118] Such as Figure 5 、 Figure 6 and Figure 7As shown, the water outlet assembly 1 is provided with a moving channel 111 and a first opening 112 penetrating through the side wall of the moving channel 111. 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 pushing 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 the water flow. The pushing member 32 can pass through the first opening 112 and be fixedly connected to the moving seat 31, and the aforementioned second pushing portion 321 is provided on the pushing member 32, and at least one of the second pushing portion 321 and the first pushing portion 23 penetrates 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 drive the moving seat 31 to move, through the sliding fit between the moving seat 31 and the moving channel 111, the moving seat 31 can be guided to prevent its movement from being offset. When installing the driving assembly 3 into the moving channel 111, the moving seat 31 can be first placed in the moving channel 111, and then the pushing member 32 can pass through the first opening 112 and enter the moving channel 111 to be connected to the moving seat 31, reducing the installation difficulty.

[0119] In this embodiment, referring to Figure 7 , the moving channel 111 includes a first channel 1111 and a second channel 1112 that are connected and communicate with each other. The first opening 112 penetrates through the side wall of the second channel 1112. The water outlet assembly 1 is further provided with a second opening 113, and the water inlet hole 161 is communicated with the first channel 1111 through the second opening 113 to introduce water into the first channel 1111 through the second opening 113. Combining Figure 8 , the moving seat 31 includes a first sliding portion 311, a mounting portion 312, and a second sliding portion 313 that are connected in sequence. The first sliding portion 311 is in sealed and sliding fit with the inner wall of the first channel 1111, and the end surface of the first sliding portion 311 facing away from the mounting portion 312 is the pressure-bearing surface 310; the mounting portion 312 is used for connecting with the pushing member 32; the second sliding portion 313 is in sealed and sliding fit 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 pushing member 32 are in sliding fit with the corresponding channels, which can improve the stability of the moving seat 31 when it moves. Since the first sliding portion 311 is in sealed contact with the inner wall of the first channel 1111, when the water flow starts to enter the first channel 1111 through the second opening 113, the water flow can all act 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, enabling the water flow to smoothly push the moving seat 31 to move. Since the second sliding portion 313 is in sealed sliding contact with the inner wall of the second channel 1112, it can prevent the water flow from flowing to the side of the second sliding portion 313 away from the pressure-bearing surface 310 through the gap between the two, avoiding the movement of the moving seat 31 from being blocked. Exemplarily, the inner diameter of the first channel 1111 is smaller than the inner diameter of the second channel 1112.

[0120] In this embodiment, when the water inlet flow pressure is greater than or equal to 0.1 MPa, it can drive the moving seat 31 to move. The water pressure of municipal water supply to ordinary households is generally between 0.2 MPa and 0.3 MPa, which is sufficient to meet the water pressure requirement of being greater than or equal to 0.1 MPa.

[0121] As Figure 6 , Figure 7 and Figure 8 shown, at least one support column 314 protrudes from the bearing surface 310, and a baffle 18 is provided at one end of the first channel 1111 far from the second channel 1112. When the shower head is not in use, the moving seat 31 remains in the reset state under the elastic force of the first reset member 4. At this time, the support column 314 abuts against the baffle 18, so that a gap H is maintained between the bearing surface 310 and the baffle 18, and this gap communicates with the second opening 113. When the shower head is turned on to let water enter the moving channel 111 through the second opening 113, due to the existence of this gap, the water inlet pressure can act on the bearing surface 310 of the first sliding portion 311, so as to smoothly drive the moving seat 31 to move, and prevent the bearing surface 310 from directly abutting against the baffle 18 under the elastic force of the first reset member 4, resulting in the moving seat 31 not being able to be driven by the water flow. Exemplarily, a plurality of support columns 314 are arranged at intervals to ensure sufficient support strength for the moving seat 31.

[0122] Combined with Figure 7 and Figure 13 , a third opening 114 is provided at one end of the second channel 1112 far from the first channel 1111. The moving seat 31 penetrates into the moving 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 provided on the second sliding portion 313, and a fixing column is provided 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 penetrates into the groove on the second sliding portion 313. The moving seat 31 and the first reset member 4 are sequentially placed into the moving channel 111 through the third opening 114, and then the sealing end cover 17 is installed and blocked at the third opening 114. After installation, the support column 314 can abut against the baffle 18 under the elastic force of the first reset member 4.

[0123] Exemplarily, referring to Figure 10 and Figure 13 , two L-shaped hooks 119 are arranged at intervals outside the third opening 114, and limiting protrusions are convexly provided on both sides of the outer wall of the sealing end cover 17. After the sealing end cover 17 is capped on the third opening 114, the sealing end cover 17 is rotated so that the limiting protrusions on both sides of it are respectively snapped into the L-shaped hooks 119 one by one, and the hooks 119 hook and hold the sealing end cover 17, realizing the detachable installation of the sealing end cover 17 at the third opening 114.

[0124] See Figure 7 and Figure 8 As shown in FIGS. and, a first sealing groove 3111 is provided around the first sliding part 311, and a first sealing ring 33 is arranged in the first sealing groove 3111. The first sealing ring 33 is in sealing and sliding contact with the inner wall of the first channel 1111, realizing the sealing sliding fit between the first sliding part 311 and the inner wall of the first channel 1111. A second sealing groove 3131 is provided around the second sliding part 313, and a second sealing ring 34 is arranged in the second sealing groove 3131. The second sealing ring 34 is in sealing and sliding contact with the inner wall of the second channel 1112, realizing the sealing sliding fit between the second sliding part 313 and the inner wall of the second channel 1112.

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

[0126] In this embodiment, see Figure 8 and Figure 9 As shown in FIGS. and, the pushing member 32 further includes a mounting plate 322 and a first buckle 323. The first buckle 323 and the second pushing part 321 are respectively arranged on both sides of the mounting plate 322. An installation groove 3121 is provided on the installation part 312 of the moving seat 31, and a second buckle 3122 protrudes from the inner wall of the installation groove 3121. The first opening 112 allows the mounting plate 322 and the first buckle 323 to pass through. When installing the pushing member 32, the mounting plate 322 and the first buckle 323 of the pushing member 32 are inserted into the moving channel 111 through the first opening 112 and enter the installation groove 3121 of the moving seat 31 until the first buckle 323 is hooked with the second buckle 3122 on the inner wall of the installation groove 3121, and at this time, the mounting plate 322 abuts against the moving seat 31 along the direction in which the first buckle 323 is inserted into the installation groove 3121. At this time, due to the hooking cooperation between the first buckle 323 and the second buckle 3122, the pushing member 32 can be blocked from disengaging from the installation groove 3121 at the first opening 112; due to the abutment between the mounting plate 322 and the moving seat 31, the pushing member 32 can be blocked from continuing to move along the insertion direction (i.e., the direction in which the pushing member 32 is inserted into the installation groove 3121). That is, the mounting plate 322 and the first buckle 323 limit the pushing member 32 in two opposite directions respectively.

[0127] Specifically, at least one group of first buckles 323 are distributed at intervals along the axial direction of the moving seat 31 on the mounting plate 322. Each group includes two first buckles 323 arranged at intervals. Second buckles 3122 are arranged on the opposite inner walls of the installation groove 3121, and the two first buckles 323 are respectively hooked on the second buckles 3122 on the opposite inner walls of the installation groove 3121 to ensure firm connection and no detachment.

[0128] See Figure 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, as Figure 4 and Figure 11 shown, the water outlet assembly 1 includes a water distribution member 11, a water inlet cover 12, and a water outlet cover 13. Among them, the water inlet cover 12 and the water outlet cover 13 are buckled with each other and define a first water passage space 14. The first water outlet hole 1321 is provided on the water outlet cover 13. The moving plate 21 is movably arranged in the first water passage space 14. The water distribution member 11 is arranged on the side of the water inlet cover 12 facing away from the water outlet cover 13 and is provided with the aforementioned moving passage 111, the first opening 112, the second opening 113, and the third opening 114, as Figure 13 shown. Combining Figure 3 and Figure 7 , a first water passage hole 121 and a fourth opening 122 are provided through the water inlet cover 12. The fourth opening 122 is directly opposite and communicated with the first opening 112. The first pushing portion 23 passes through the fourth opening 122 so as to be in sliding contact with the second pushing portion 321 arranged in the first opening 112. The water distribution member 11 is provided with a first water distribution port 115. The water inlet hole 161 is communicated with both the moving passage 111 and the first water passage hole 121 through the first water distribution port 115. The water flow introduced from the first water distribution port 115 enters the flow passage defined between the water distribution member 11 and the water inlet cover 12. Then, a part of the water flow enters the moving passage 111 through the second opening 113 and contacts the pressure-bearing surface 310 to drive the moving seat 31 to move, and the other part enters the first water passage space 14 through the first water passage hole 121 on the water inlet cover 12 and is then output through the first water outlet hole 1321.

[0135] Furthermore, referring to Figure 11 , the water outlet cover 13 includes a cover plate 131 and a water outlet sleeve 132 which are stacked. 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 arranged on the rubber pad. Each rubber sleeve is provided with the aforementioned first water outlet hole 1321. The plurality of rubber sleeves respectively penetrate through the plurality of through holes on the cover plate 131. The rubber pad is located between the cover plate 131 and the moving 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 opened on the cover plate 131.

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

[0137] In this embodiment, through the cooperation of the driving component 3 and the descaling needle plate 2, automatic descaling can be realized under the action of water flow pressure. To improve the descaling flexibility of this 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 through the water flow pressure, the manual descaling function can be started to achieve descaling, improving the user experience.

[0138] Specifically, as shown in Figure 4 , Figure 10 and Figure 11 , the scale removal and pressure increasing shower head further includes a scale removal button 6, a transmission member 7 and a push plate 8. The scale removal button 6 is movably inserted through the water outlet assembly 1, and specifically, in this embodiment, it is inserted through the central part of the water outlet assembly 1. The transmission member 7 is movably connected to the scale removal 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 scale removal needle 22 and is fixedly connected to the moving plate 21. When the scale removal button 6 is manually pressed, the scale removal button 6 can move relative to the water outlet assembly 1. When the scale removal button 6 moves, it drives the push plate 8 to move through the transmission member 7, and then the push plate 8 drives the moving plate 21 to move to the first position, so that the scale removal needle 22 penetrates the first water outlet hole 1321. When the push plate 8 is driven to move by the scale removal button 6. The moving direction of the push plate 8 is the same as the moving direction of the scale removal needle plate 2 and opposite to the moving direction of the scale removal button 6. In this way, when the scale removal button 6 is inserted at the center of the water outlet surface cover 13 and is pressed and moved along the axis direction of the water outlet surface cover 13 towards the back of the shower head, it can drive the scale removal needle plate 2 to move towards the water outlet surface of the shower head (i.e., the side of the water outlet surface cover 13 facing away from the water inlet surface cover 12) to penetrate the first water outlet hole 1321. Referring to Figure 4 for the orientation in, when the scale removal button 6 is pressed upward, the push plate 8 can be driven by the transmission member 7 to move downward, so as to drive the scale removal 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 distribution member 11. When the scale removal needle plate 2 moves in the direction of penetrating the first water outlet hole 1321, it compresses the second reset member 5 through the push plate 8. When the water flow pressure disappears or the scale removal button 6 stops being pressed, the second reset member 5 releases its elastic potential energy, so that the scale removal needle plate 2 is reset under the elastic force of the second reset member 5.

[0140] As shown in Figure 14 , Figure 15 and Figure 16 , the scale removal button 6 includes a pressing portion 61 and a push post 62 protruding from the pressing portion 61. The pressing portion 61 is used to receive the pressing force of the user, and the push post 62 is movably connected to the transmission member 7 to drive the push plate 8 to move through the transmission member 7.

[0141] Specifically, a third pushing portion 621 is convexly provided on the outer wall of the push post 62 of the descaling button 6. The third pushing portion 621 is slidably abutted against the transmission member 7, so that the descaling button 6 drives the transmission member 7 to move when being pressed. The transmission member 7 includes a rotating cylinder 71 sleeved on the push post 62, a fourth pushing portion 72 convexly provided on the inner wall of the rotating cylinder 71, and a fifth pushing portion 73 convexly provided on the outer wall of the rotating cylinder 71. The axial direction of the rotating cylinder 71 is consistent with the moving direction of the descaling button 6, both being the axial direction of the water outlet cover 13. The fourth pushing portion 72 is provided with a first inclined surface 721, and the fifth pushing portion 73 is provided with a second inclined surface 731. Both the first inclined surface 721 and the second inclined surface 731 are inclined relative to the axial direction of the rotating cylinder 71. The push plate 8 is provided with a transmission groove 83. The transmission member 7 is rotatably arranged in the transmission groove 83 around its own axis; a sixth pushing portion 84 is convexly provided on the inner wall of the transmission groove 83, and the sixth pushing portion 84 is provided with a third inclined surface 841 which is inclined relative to the axial direction of the rotating cylinder 71. The third pushing 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 pushing portion 621 and is in sliding cooperation with the first inclined surface 721 to drive the rotating cylinder 71 of the transmission member 7 to rotate around its own axis. When the rotating cylinder 71 rotates around its own axis, the fifth pushing portion 73 on its outer wall moves synchronously. The fifth pushing portion 73 pushes the third inclined surface 841 through the second inclined surface 731 and is in sliding cooperation with the third inclined surface 841, thereby driving the push plate 8 to move. The push plate 8 drives the descaling needle plate 2 to move to realize the descaling and pressure boosting function.

[0143] Further, a plurality of third pushing portions 621 are evenly convexly provided on the push post 62 in the circumferential direction. A plurality of fourth pushing portions 72 are evenly convexly provided on the inner wall of the rotating cylinder 71 to form a plurality of first inclined surfaces 721. A plurality of fifth pushing portions 73 are evenly convexly provided on the outer wall of the rotating cylinder 71 to form a plurality of second inclined surfaces 731. A plurality of sixth pushing portions 84 are evenly convexly provided on the inner wall of the transmission groove 83 to form a plurality of third inclined surfaces 841. The plurality of third pushing portions 621 are slidably abutted and cooperated with the plurality of first inclined surfaces 721 one by one, and the plurality of second inclined surfaces 731 are slidably abutted and cooperated with the plurality of third inclined surfaces 841 one by one, improving the force balance of the transmission member 7 and the push plate 8 during the process of pressing the descaling button 6 and making the transmission process more stable.

[0144] Specifically, referring to Figure 14 and Figure 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 the same as the axial direction of the cylinder body 82, and the inner hole of the cylinder body 82 is the above-mentioned transmission groove 83.

[0145] AsFigure 4 As shown, a sliding hole 1312 is provided at the center position of the cover plate 131 of the water outlet cover 13. Through holes that are aligned with and communicate with the sliding hole 1312 are provided on both the water inlet cover 12 and the water distribution member 11. The push plate 8 is located on the side of the water distribution member 11 facing away from the water inlet cover 12. The pressing portion 61 of the descaling button 6 is slidably engaged with the sliding hole 1312, and the push column 62 passes through the through holes on both the water inlet cover 12 and the water distribution member 11 and enters the rotating cylinder 71 in the transmission groove 83. Moreover, the through holes on both the water inlet cover 12 and the water distribution member 11 can avoid the cylinder body 82 of the push plate 8 to prevent interference with the two when the push plate 8 moves.

[0146] Further, one of the inner wall of the sliding hole 1312 and the pressing portion 61 is provided with a guiding protrusion 611, and the other is provided with a sliding groove 1313. The guiding protrusion 611 is slidably disposed in the sliding groove 1313 to guide the sliding of the pressing portion 61 in the sliding hole 1312. Exemplarily, the above-mentioned sliding groove 1313 is recessed on the inner wall of the sliding hole 1312. Figure 15 Combined with, the above-mentioned guiding protrusion 611 protrudes from the outer wall of the pressing portion 61. A plurality of guiding protrusions 611 and sliding grooves 1313 can be provided in one-to-one correspondence.

[0147] See Figure 4 , the water outlet assembly 1 is provided with a stop portion 1314. The stop portion 1314 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 stop portion 1314 is disposed at one end of the sliding groove 1313 and is used to abut against the guiding protrusion 611 to block the guiding protrusion 611 from sliding out of the sliding groove 1313 and avoid the descaling button 6 from falling off.

[0148] See Figure 10 and Figure 11 , an installation column 24 is connected to the moving plate 21. The installation column 24 is movably penetrated through the water inlet cover 12 and the water distribution member 11 and is connected to the push plate 8 through a first fastener 9 to realize the fixed connection between the push plate 8 and the descaling needle plate 2 and make the two move synchronously. Exemplarily, the first fastener 9 is a screw.

[0149] See Figure 10 , a limiting plate 10 is provided on the side of the push plate 8 facing away from the water distribution member 11. The limiting plate 10 is connected to the water distribution member 11 so that the push plate 8 can only move between the limiting plate 10 and the water distribution member 11 to limit the moving stroke of the push plate 8. Further, a guiding column 85 is provided on one of the limiting plate 10 and the push plate 8, and a guiding hole 101 is provided on the other. The guiding column 85 penetrates through the guiding hole 101 and is slidably engaged with the guiding hole 101 to guide the movement of the push plate 8 and prevent the push plate 8 from moving out of position. In this embodiment, at least one guiding column 85 protrudes from the push plate 8, and guiding holes 101 corresponding to the guiding columns 85 one by one are provided on the limiting plate 10.

[0150] More specifically, refer to Figure 10 and Figure 12 . On the water distribution member 11, a first connecting post 1110 is convexly provided. The limiting plate 10 is placed on the first connecting post 1110 and is fixedly connected to the first connecting post 1110 through a second fastener 20. Exemplarily, the second fastener 20 is a screw.

[0151] In this embodiment, as Figure 1 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 circle of the second water outlet hole 1311. The water inlet hole 161 is selectively communicated 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 to discharge water or use the second water outlet hole 1311 to discharge water. Specifically, the second water outlet hole 1311 is directly provided on the cover plate 131.
