Description

Technical Field

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

[0002] Showers dispense water through the outlet holes on the water outlet panel. Most showerheads have fixed-size outlet holes. As water pressure fluctuates, the force of the water spraying from the holes also varies. Especially at low water pressure, the spray force is weak, resulting in incomplete showers and prolonged showers. Furthermore, because impurities such as sediment often accumulate in water pipes, after prolonged use, these impurities can accumulate in the outlet holes, clogging them and causing water to flow obliquely or even completely blocked, resulting in a poor showering experience.

[0003] Some existing shower heads achieve descaling by adding a movable cleaning and descaling device. The cleaning and descaling device moves under the drive of a driving structure such as a knob or button, so that the descaling needle on it penetrates the water outlet hole on the water outlet panel to achieve descaling.

[0004] The existing technology has the following defects: the method of driving the cleaning and descaling device to move by means of a knob or button requires manual operation, i.e., manual descaling. If the user does not descaling regularly, scale will still accumulate at the water outlet, causing abnormal water flow from the shower head. Moreover, the user will only descaling after scale has accumulated, which will cause great resistance to descaling. There will be a sense of frustration when the descaling needle is inserted into the water outlet, and the descaling device is easily damaged and fails.

[0005] Therefore, there is an urgent need for a pressurized descaling shower head to solve the above problems existing in the prior art. Utility Model Content

[0037] Beneficial effects of the utility model:

[0038] The utility model provides a pressurized descaling shower head, which can realize pressurized water discharge and automatic descaling by setting the descaling component in a movable form under the action of water flow pressure. When the water flow pressure on the descaling component is less than the first pressure threshold, the water flow pressure at this time cannot resist the force of the reset member, and the descaling component is in a first state in contact with the inner wall of the first water outlet. When the water flow pressure on the descaling component is greater than or equal to the first pressure threshold and less than the second pressure threshold, the water flow pressure at this time can make the descaling component move relative to the water outlet component to compress the reset member and move to the second state. The descaling component in the second state is still arranged in the first water outlet but there is a gap between it and the inner wall of the first water outlet. Compared with the third state in which the descaling component is separated from the first water outlet, the water outlet area can be reduced, thereby increasing the water outlet pressure, ensuring that the water outlet has a certain force, and achieving the purpose of pressurized water discharge at low water pressure. When the water pressure acting on the descaling assembly is greater than or equal to the second pressure threshold, the water pressure causes the descaling assembly to move to the third state, disengaged from the first water outlet, and compress the reset element. Water now flows out of the first water outlet over a wide area, creating a gentle flow and preventing significant impact on the user. When the water is turned off, the water pressure acting on the descaling assembly drops below the first pressure threshold. The compressed reset element releases potential energy, driving the descaling assembly to move relative to the water outlet assembly to the first state, where it engages in sliding frictional contact with the inner wall of the first water outlet, achieving automatic descaling without the need for manual operation and enhancing the user's shower experience.

[0076] 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 in different embodiments are omitted.

[0077] like Figure 1 、 Figure 2 as well as Figure 3 As shown, this embodiment provides a pressurized descaling shower head, which can adjust the water spray pressure at the water outlet when the water pressure in the water channel is low to ensure the water output strength. At the same time, it can also achieve automatic descaling without manual operation, thereby improving the user's shower experience.

[0078] The shower head includes a water outlet assembly 1, a descaling assembly 2 and a reset member 3. The water outlet assembly 1 has a plurality of first water outlet holes 122; the descaling assembly 2 is movably arranged in the water outlet assembly 1, and has a first state in contact with the inner wall of the first water outlet hole 122, a second state in which it is spaced apart and penetrates into the first water outlet hole 122, and a third state in which it is separated from the first water outlet hole 122. Specifically, in the first state, the descaling assembly 2 at least partially penetrates the first water outlet hole 122 and is in contact with the inner wall of the first water outlet hole 122. In the second state, the descaling assembly 2 at least partially penetrates into the first water outlet hole 122, and there is a gap between it and the inner wall of the first water outlet hole 122. In the third state, the descaling assembly 2 is completely separated from the first water outlet hole 122. The descaling assembly 2 is at least partially in contact with the water flow in the water outlet assembly 1; the reset member 3 is connected between the water outlet assembly 1 and the descaling assembly 2. The descaling assembly 2 switches between the first state, the second state, and the third state as the water pressure changes. Specifically, in this embodiment, the reset member 3 is used to drive the descaling assembly 2 to the first state when the water pressure applied to the descaling assembly 2 is less than the first pressure threshold. The descaling assembly 2 moves to the second state relative to the water outlet assembly 1 when the water pressure applied to the descaling assembly 2 is greater than or equal to the first pressure threshold and less than the second pressure threshold; the descaling assembly 2 moves to the third state relative to the water outlet assembly 1 when the water pressure applied to the descaling assembly 2 is greater than or equal to the second pressure threshold; wherein the first pressure threshold is less than the second pressure threshold. The shower head provided in this embodiment achieves pressurized water discharge and automatic descaling by configuring the descaling assembly 2 to be movable under the action of water pressure.

[0079] Specifically, when the water flow pressure on the descaling component 2 is less than the first pressure threshold, the water flow pressure at this time cannot resist the force of the reset member 3, and the descaling component 2 is in the first state of contact with the inner wall of the first water outlet 122. When the water flow pressure on the descaling component 2 is greater than or equal to the first pressure threshold and less than the second pressure threshold, the water flow pressure at this time can cause the descaling component 2 to move relative to the water outlet component 1, thereby compressing the reset member 3 and moving to the second state. In the second state, the descaling component 2 is still installed in the first water outlet 122 but there is a gap between it and the inner wall of the first water outlet 122. Compared with the third state in which the descaling component 2 is separated from the first water outlet 122, the water outlet area can be reduced, thereby increasing the water outlet pressure, ensuring that the water outlet has a certain force, and achieving the purpose of pressurized water outlet at low water pressure. When the water pressure on the descaling component 2 is greater than or equal to the second pressure threshold, the descaling component 2 moves to the third state, disengaged from the first water outlet 122, and compresses the reset member 3 under the action of the water pressure. At this time, the water outlet area through the first water outlet 122 is large and the water outlet is soft, avoiding the water flow causing a large impact on the user, and realizing a large-surface water outlet mode. When the water is turned off, the water pressure on the descaling component 2 becomes less than the first pressure threshold. At this time, the compressed reset member 3 releases potential energy, driving the descaling component 2 to move relative to the water outlet component to the first state, during which time it is in sliding friction contact with the inner wall surface of the first water outlet 122, realizing automatic descaling without the need for manual descaling, and improving the user's shower experience.

[0080] Exemplarily, the reset member 3 is a spring.

[0081] In this embodiment, see Figure 6 The water outlet assembly 1 is provided with a water inlet 110 and a first water channel 20. The water inlet 110 can communicate with the first water outlet 122 through the first water channel 20. The descaling assembly 2 is at least partially movably disposed within the first water channel 20. The descaling assembly 2 moves relative to the water outlet assembly 1 under the action of the water flow pressure in the first water channel 20, so that the descaling assembly 2 switches between the first state, the second state, and the third state, thereby achieving pressurized water discharge when the water pressure is low and automatic descaling when the water is turned off.

[0082] Specifically, the water pressure in the first water channel 20 is used to move the descaling assembly 2. When the water pressure on the descaling assembly 2 is greater than or equal to the second pressure threshold, the descaling assembly 2 is separated from the first water outlet 122, and the water flowing into the water inlet 110 flows through the first water channel 20 to the first water outlet 122, increasing the water outlet area, and the shower head switches to the large-surface water outlet mode. When the water pressure on the descaling assembly 2 is greater than or equal to the first pressure threshold and less than the second pressure threshold, that is, when the water pressure is low, the descaling assembly 2 remains in the second state under the combined action of the water pressure and the reset member 3. The water flowing into the water inlet 110 flows out through the gap between the descaling assembly 2 and the inner wall of the first water outlet 122. Compared with the case where the descaling assembly 2 is completely separated from the first water outlet 122, the water outlet area is reduced and the water outlet force is increased, achieving pressurized water outlet at low water pressure. At this time, the shower head is in the pressurized water outlet mode. When the water is turned off, the water pressure on the descaling component 2 becomes zero, and the descaling component 2 moves to the first state under the action of the reset member 3, and realizes automatic descaling through sliding contact with the inner wall surface of the first water outlet 122.

[0083] The above-mentioned first pressure threshold is greater than 0. For example, the first pressure threshold is 0.2 MPa, and the second pressure threshold is 0.25 MPa. When the water flow pressure on the descaling component 2 is greater than or equal to 0.2 MPa and less than 0.25 MPa, the descaling component 2 is at least partially disposed within the first water outlet 122 and is spaced apart from the inner wall of the first water outlet 122. At this time, the shower head is in a pressurized water outlet mode. When the water flow pressure on the descaling component 2 is greater than 0.25 MPa, the descaling component 2 is separated from the first water outlet 122, and the shower head is in a wide-surface water outlet mode.

[0084] It should be noted that the first and second pressure thresholds described above are related to the elastic force of the reset member 3. Only when the water pressure is greater than or equal to the first pressure threshold can the descaling assembly 2 overcome the elastic force of the reset member 3 and thus move relative to the water outlet assembly 1. The elastic force of the reset member 3 is set based on the normal municipal water pressure. Specifically, a reset member 3 with an appropriate elastic coefficient is selected based on the normal municipal water pressure.

[0085] In this embodiment, see Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5The descaling assembly 2 includes a driving mechanism 21 and a descaling rack 22. The driving mechanism 21 is movably arranged in the water outlet assembly 1 and is at least partially located in the first water channel 20; the descaling rack 22 includes a descaling plate 221 and a plurality of descaling needles 222 arranged on the descaling plate 221. The descaling plate 221 is movably arranged in the first water channel 20 and is in transmission connection with the driving mechanism 21. The driving mechanism 21 can drive the descaling plate 221 to move under the action of water pressure. The descaling needles 222 have a state of contacting with the inner wall of the first water outlet hole 122, a state of being intermittently inserted into the first water outlet hole 122, and a state of being separated from the first water outlet hole 122. The descaling needles 222 can switch between the above three states under the drive of the descaling plate 221. The reset member 3 is arranged between the descaling plate 221 and the inner wall of the first water channel 20.

[0086] Specifically, when the water pressure applied to the driving mechanism 21 in the first water channel 20 is less than a first pressure threshold, the water pressure is insufficient to enable the driving mechanism 21 to drive the descaling rack 22 to move. When the water pressure applied to the driving mechanism 21 is greater than or equal to the first pressure threshold and less than a second pressure threshold, the water pressure can cause the driving mechanism 21 to move relative to the water outlet assembly 1. At this time, the driving mechanism 21 drives the descaling rack 22 to move in the first water channel 20 away from the first water outlet hole 122. Driven by the descaling plate 221, the descaling needle 222 moves from a state of penetrating and contacting the inner wall of the first water outlet hole 122 to a state of being spaced apart from the inner wall of the first water outlet hole 122. Water is ejected through the gap between the descaling needle 222 and the inner wall of the first water outlet hole 122, achieving pressurized water outlet at low water pressure. When the water flow pressure on the driving mechanism 21 is greater than the second pressure threshold, under the action of the water pressure, the driving mechanism 21 drives the descaling plate 221 to continue to move away from the first water outlet 122, so that the descaling needle 222 moves away from the first water outlet 122, realizing the large-surface water outlet mode. The descaling frame 22 compresses the reset member 3 in the process of moving away from the first water outlet 122, so that the reset member 3 accumulates potential energy. When the water is turned off, the water flow pressure on the driving mechanism 21 in the first water channel 20 is zero, and the reset member 3 releases potential energy, so that the descaling frame 22 drives the descaling needle 222 to move to a position that passes through the first water outlet 122 and contacts the inner wall of the first water outlet 122, and at the same time drives the driving mechanism 21 to reset. During the movement of the descaling needle 222, automatic descaling is achieved through sliding friction with the inner wall of the first water outlet 122.

[0087] like Figure 2 、 Figure 3 as well as Figure 7 As shown, a transmission shaft 223 is provided on the side of the descaling plate 221 facing away from the descaling needle 222 for transmission connection with the driving mechanism 21. The driving mechanism 21 includes a lever 211 and a movable shaft 212.

[0088] Among them, the lever 211 is swingably arranged on the water outlet component 1, and has a first end 2111 and a second end 2112. The first end 2111 and the second end 2112 are respectively arranged on both sides of the swing center of the lever 211; when the lever 211 swings around the swing center, the first end 2111 and the second end 2112 move in different directions respectively. The transmission shaft 223 is movably arranged through the water outlet component 1, and one end extends out of the first water channel 20 and is movably connected to the first end 2111; the movable shaft 212 is movably arranged through the first water channel 20 between the first position and the second position, and one end extends out of the first water channel 20 and is movably connected to the second end 2112. The movable shaft 212 is used to drive the transmission shaft 223 and the descaling rack 22 to move through the lever 211 under the action of water pressure, thereby realizing the switching of the state of the descaling needle 222. Figure 2 and Figure 3 When the lever 211 moves, the movable shaft 212 and the transmission shaft 223 move in opposite directions.

[0089] When the movable shaft 212 is in the first position, the descaling needle 222 contacts the inner wall of the first water outlet 122. When the movable shaft 212 is in the second position, the descaling needle 222 is separated from the first water outlet 122. When the movable shaft 212 is between the first position and the second position, the descaling needle 222 is located within the first water outlet 122 and spaced apart from the inner wall of the first water outlet 122. The movable shaft 212 in the first position is configured to move toward the second position when the water pressure is greater than or equal to a first pressure threshold. The movable shaft 212 then drives the lever 211 to swing relative to the water outlet assembly 1, causing the first end 2111 of the lever 211 to drive the transmission shaft 223 to move. The transmission shaft 223 then drives the descaling frame 22 to move, causing the descaling needle 222 to move away from the first water outlet 122 under the drive of the descaling frame 22. When the water is turned off, the reset member 3 moves the descaling rack 22 to a position penetrating and contacting the inner wall of the first water outlet 122, thereby driving the lever 211 to swing through the transmission shaft 223, so that the second end 2112 of the lever 211 drives the movable shaft 212 to reset to the first position and remain in the first position under the action of the reset member 3. Figure 3 and Figure 8 As shown, it is a schematic diagram when the movable shaft 212 is in the first position.

When the descaling needle 222 moves away from the first water outlet hole 122, there can be a gap between the inner wall surface of the first water outlet hole 122.

[0091] In this embodiment, the outlet assembly 1 is further provided with a second outlet hole 121. The showerhead selectively discharges water through the second outlet hole 121 or through the first outlet hole 122, thereby providing the showerhead with both a second outlet hole 121 and a first outlet hole 122 mode. Furthermore, the outlet assembly 1 is further provided with a second water channel 10, through which the water inlet 110 communicates with the second outlet hole 121.

[0092] In this embodiment, descaling needles 222 are only provided for a plurality of first water outlet holes 122 , and the number and distribution of the descaling needles 222 are consistent with the number and distribution of the first water outlet holes 122 , so that the plurality of descaling needles 222 can descaling the plurality of first water outlet holes 122 one by one.

[0093] In this embodiment, see Figure 4 The shower head further includes a housing 4 and a connecting base 5. The housing 4 is provided with a water inlet channel 42. The connecting base 5 is mounted on the housing 4 to achieve the installation and positioning of the water outlet assembly 1 on the housing 4. Specifically, the water outlet assembly 1 includes a water diverter 11 and a water outlet surface cover 12. The water diverter 11 and the water outlet surface cover 12 are snap-fitted and connected, and the water diverter 11 is sandwiched between the base 51 and the water outlet surface cover 12. The water diverter 11 and the water outlet surface cover 12 define the second water channel 10 and the first water channel 20 mentioned above. The second water outlet hole 121 and the first water outlet hole 122 are both provided on the water outlet surface cover 12.

[0094] Combine Figure 5 The connection seat 5 includes a seat body 51 and a positioning column 52 provided on the seat body 51. The seat body 51 is connected to the housing 4 and is provided with a water inlet hole. The positioning column 52 is used to position the water distribution member 11 and the water outlet cover 12. Specifically, the positioning column 52 coaxially penetrates the water distribution member 11 and the water outlet cover 12 to locate the installation position of the entire water outlet assembly 1 on the housing 4. Figure 12 FIG. 5 is a schematic diagram of the installation of the connecting seat 5 on the housing 4. The first fastener 7 passes through the seat body 51 and is threadedly connected to the housing 4 to achieve the fixation of the connecting seat 5. Figure 13 The housing 4 is provided with a water inlet channel 42, which is connected to the water inlet 511 on the base 51. The water inlet portion 110 is provided on the water diversion member 11. The water inlet channel 42 is connected to the water inlet portion 110 on the water diversion member 11 through the water inlet 511 on the connecting base 5, so as to flow water into the water diversion member 11.

[0095] See also Figure 6The first water channel 20 includes a first water diversion channel 201 provided in the water diversion member 11 and a first cavity 203 enclosed by the water diversion member 11 and the water outlet cover 12, and the first water outlet hole 122 is located on the bottom wall of the first cavity 203.

Furthermore, the water inlet portion 110 on the water diversion member 11 includes a first water diversion hole and a second water diversion hole that are not connected to each other. The second water diversion hole is connected to the second cavity 102 through the second water diversion channel 101, and the first water diversion hole is connected to the first cavity 203 through the first water diversion channel 201. The descaling plate 221 in this embodiment is movably arranged in the first cavity 203, and the reset member 3 is arranged between the descaling plate 221 and the water diversion member 11.

[0096] The water flow input into the water inlet channel 42 of the shell 4 selectively enters the second water diversion hole or the first water diversion hole through the water inlet 511 on the connecting seat 5. The water flow at the first water diversion hole can flow to the first cavity 203 and be sprayed out through the first water outlet hole 122. The water flow at the second water diversion hole flows into the second cavity 102 and flows out through the second water outlet hole 121.

[0097] See also Figure 2 and Figure 3 The lever 211 and the movable shaft 212 are both arranged on the water diversion member 11 , the lever 211 is swingably arranged outside the water diversion member 11 , and the movable shaft 212 and the transmission shaft 223 of the descaling rack 22 movably penetrate the water diversion member 11 .

[0098] See also Figure 5 The water diversion member 11 includes an upper water diversion body 111 and a lower water diversion body 112. The second water diversion hole and the first water diversion hole are provided on the upper water diversion body 111. The lower water diversion body 112 is located between the upper water diversion body 111 and the water outlet cover 12. The second water diversion path 101 and the first water diversion path 201 are defined between the upper water diversion body 111 and the lower water diversion body 112, and the second cavity 102 and the first cavity 203 are defined between the lower water diversion body 112 and the water outlet cover 12.

[0099] Furthermore, the water diversion member 11 composed of the upper water diversion body 111 and the lower water diversion body 112 can be an integrated structure or a split structure. When it is a split structure, the upper water diversion body 111 and the lower water diversion body 112 can be separately processed and then assembled together.

[0100] See also Figure 5 and Figure 7The water distribution member 11 and the water outlet cover 12 are fixedly connected by a second fastener 8. The second fastener 8 is threadedly connected to the water outlet cover 12 to ensure a stable connection and good sealing. The first fastener 7 and the second fastener 8 can both be screws.

[0101] When assembling the shower head, the connecting base 5 can be first fixed to the inner side of the shell 4 using the first fastener 7, and the water distribution piece 11, the water outlet cover 12, the descaling assembly 2, etc. can be connected together. Finally, it can be positioned by the positioning column 52 of the connecting base 5 and installed on the shell 4.

[0102] See also Figure 5 、 Figure 7 and Figure 8 A rotating seat 118 is provided on the outer wall of the water distribution member 11 , and a rotating shaft 23 is passed through the lever 211 , and the lever 211 is rotatably connected to the rotating seat 118 through the rotating shaft 23 .

[0103] In this embodiment, see Figure 2 、 Figure 3 、 Figure 8 as well as Figure 10 The first water channel 20 also includes a mounting channel 202, through which the first water channel 201 communicates with the first cavity 203. The movable shaft 212 includes a connecting shaft body 2121 and a pressure-bearing portion 2122 disposed around the connecting shaft body 2121. The pressure-bearing portion 2122 is movably disposed in the mounting channel 202 and is configured to move when subjected to a water pressure greater than or equal to a first pressure threshold. The mounting channel 202 can provide a guide for the movement of the pressure-bearing portion 2122, and the pressure-bearing portion 2122 can provide a larger pressure-bearing surface, allowing the movable shaft 212 to move under the action of water pressure. The end of the connecting shaft body 2121 away from the pressure-bearing portion 2122 extends out of the first water channel 20 and is connected to the second end 2112. The connecting shaft body 2121 is sealed and slidably engaged with the water outlet assembly 1. Specifically, the connecting shaft body 2121 passes through the water diversion component 11 and is movably connected to the second end 2112 of the lever 211 outside the water diversion component 11. On the one hand, the sliding fit between the connecting shaft 2121 and the water diversion member 11 can improve the guiding accuracy of the movable shaft 212 and improve the movement stability of the movable shaft 212. On the other hand, the sealing fit between the connecting shaft 2121 and the water diversion member 11 ensures that water will not overflow.

[0104] When the water pressure on the pressure-receiving portion 2122 in the installation channel 202 is less than the first pressure threshold, the water pressure is insufficient to move the movable shaft 212. At this time, the movable shaft 212 remains in the first position, and the descaling needle 222 penetrates and contacts the inner wall surface of the first water outlet 122. When the water pressure on the pressure-receiving portion 2122 is greater than or equal to the first pressure threshold, the water pressure drives the movable shaft 212 to move. Furthermore, when the water pressure is less than the second pressure threshold, the movable shaft 212 is between the first position and the second position, and drives the descaling frame 22 to rise, so that there is a gap between the descaling needle 222 and the first water outlet 122, achieving pressurized water discharge. When the water pressure is greater than or equal to the second pressure threshold, the movable shaft 212 moves to the second position, driving the descaling frame 22 to fully rise, so that the descaling needle 222 is separated from the first water outlet 122, that is, Figure 8 The status shown switches to Figure 10 After the water is turned off, the water pressure disappears, and the reset member 3 rebounds the descaling plate 221 to the position where it is inserted into the first water outlet 122, and descaling is achieved by sliding friction with the inner wall of the first water outlet 122. At the same time, the transmission shaft 223 drives the movable shaft 212 to move and reset to the second position through the lever 211. Figure 10 The status shown switches to Figure 8 The status shown.

[0105] See also Figure 8 The water-dividing member 11 is provided with a first through-hole for passing the movable shaft 212, and a first receiving groove 113 is provided above the first through-hole. A first sealing member 13 is provided in the first receiving groove 113. The first sealing member 13 is sleeved outside the movable shaft 212 to ensure a good seal between the movable shaft 212 and the water-dividing member 11. The water-dividing member 11 is also provided with a first annular groove on the outer periphery of the first receiving groove 113. The first annular groove is arranged outside the first receiving groove 113 and forms a first boss 114 between the first receiving groove 113. A first pressure cover 14 is provided in the first annular groove. The first pressure cover 14 is buckled on the first boss 114 and covers the first receiving groove 113, confining the first sealing member 13 in the first receiving groove 113 to prevent the first sealing member 13 from moving when the movable shaft 212 moves.

[0106] See also Figure 9The water-dividing member 11 is provided with a second through-hole for passing the transmission shaft 223. A second receiving groove 115 is provided above the second through-hole. A second sealing member 15 is provided in the second receiving groove 115. The second sealing member 15 is sleeved outside the transmission shaft 223 to ensure a good seal between the transmission shaft 223 and the water-dividing member 11. The water-dividing member 11 is also provided with a second annular groove on the outer periphery of the second receiving groove 115. The second annular groove is arranged outside the second receiving groove 115 and forms a second boss 116 between the second receiving groove 115. A second pressure cover 16 is provided in the second annular groove. The second pressure cover 16 is buckled on the second boss 116 and covers the second receiving groove 115, confining the second sealing member 15 in the second receiving groove 115 to prevent the second sealing member 15 from moving when the transmission shaft 223 moves.

[0107] like Figure 5 and Figure 10 As shown, the pressure surface of the pressure part 2122 is concavely provided with a groove 2120. The setting of the groove 2120 is used to avoid the protruding part above the groove 2120 on the one hand, and on the other hand, it can provide a larger space to accommodate water flow, ensuring that the pressure part 2122 can drive the lever 211 to move under the action of water flow pressure.

[0108] See also Figure 8 and Figure 10 A first guide structure 2123 is provided on the pressure-bearing portion 2122, and a second guide structure 123 is provided on the inner wall of the first water channel 20. The first guide structure 2123 and the second guide structure 123 are slidably engaged in the direction of movement of the movable shaft 212. Specifically, the first guide structure 2123 is provided on the side of the pressure-bearing portion 2122 facing away from the connecting shaft 2121, and the second guide structure 123 is provided on the side of the water outlet cover 12 facing the water diversion member 11. When the movable shaft 212 moves between the first position and the second position, the first guide structure 2123 and the second guide structure 123 slidably engage, further improving the movement stability of the movable shaft 212.

[0109] like Figure 11 As shown, the first end 2111 of the lever 211 is provided with a first mounting hole for installing the transmission shaft 223, and the second end 2112 of the lever 211 is provided with a second mounting hole for installing the movable shaft 212, thereby realizing the movable connection between the transmission shaft 223 and the first end 2111, and the movable connection between the movable shaft 212 and the second end 2112.

[0110] Specifically, the first mounting hole includes a first through hole 2111a and a first strip hole 2111b that are interconnected. The inner diameter of the first through hole 2111a is greater than the width of the first strip hole 2111b. The connecting shaft 2121 of the transmission shaft 223 is recessed to form a first constricted portion 2231 (see FIG. Figure 9), the width of the first strip-shaped hole 2111b is greater than the diameter of the first constricted portion 2231 and smaller than the diameter of the transmission shaft 223. The transmission shaft 223 can enter the first strip-shaped hole 2111b through the first through-hole 2111a, and the first constricted portion 2231 is engaged with the first strip-shaped hole 2111b. The first constricted portion 2231 is movable within the first strip-shaped hole 2111b to accommodate the movement of the lever 211.

[0111] The second mounting hole includes a second through hole 2112a and a second bar hole 2112b that are interconnected. The inner diameter of the second through hole 2112a is greater than the width of the second bar hole 2112b. The movable shaft 212 is recessed to form a second constricted portion 2124 (see Figure 10 ), the width of the second strip-shaped hole 2112b is greater than the diameter of the second constricted portion 2124 and smaller than the diameter of the connecting shaft 2121. The movable shaft 212 can enter the second strip-shaped hole 2112b through the second through-hole 2112a, and the second constricted portion 2124 is engaged with the second strip-shaped hole 2112b. The second constricted portion 2124 is movable within the second strip-shaped hole 2112b to accommodate the movement of the lever 211.

[0112] Furthermore, the first strip hole 2111b is located on the side of the first through hole 2111a facing away from the second through hole 2112a, and the second strip hole 2112b is located on the side of the second through hole 2112a facing away from the first through hole 2111a, so as to facilitate the connection between the lever 211 and the transmission shaft 223 and the movable shaft 212.

[0113] In this embodiment, the water outlet assembly 1 is rotatably mounted on the housing 4, and the lever 211 is located between the water outlet assembly 1 and the housing 4. Figure 3 and Figure 7 The first end 2111 and the second end 2112 of the lever 211 are connected with an inclined guide portion 2113. Along the direction from the first end 2111 to the second end 2112, the inclined guide portion 2113 gradually moves away from the second water outlet 121. Figure 3 In the middle position, the first end 2111 of the lever 211 is lower than the second end 2112, and the inclined guide portion 2113 gradually tilts upward along the direction from the first end 2111 to the second end 2112.

[0114] See also Figure 13 and Figure 14The inner wall of the housing 4 is provided with a protruding push-switch portion 41, which slidably cooperates with the inclined guide portion 2113 to implement a manual descaling function. Specifically, when manual descaling is required, the water outlet assembly 1 is rotated relative to the housing 4, and the lever 211 provided on the water outlet assembly 1 simultaneously rotates around the rotation axis of the water outlet assembly 1. During this rotation, the inclined guide portion 2113 slidably cooperates with the push-switch portion 41, so that the lever 211, under the pushing action of the push-switch portion 41, drives the movable shaft 212 to move between the first position and the second position, so that the descaling needle 222 can slide and rub against the inner wall of the first water outlet hole 122, achieving manual descaling.

[0115] When there is no water pressure in the shower or the movable shaft 212 is always under the action of water pressure less than the second pressure threshold, the shower cannot realize the automatic descaling function or the descaling effect is poor. At this time, the water outlet component 1 can be driven to rotate relative to the shell 4 for manual descaling, which is more practical.

[0116] Further, see Figure 1 and Figure 14 The water outlet assembly 1 is provided with a screwing operation part 124, which is more convenient and labor-saving to operate the water outlet assembly 1 by screwing the operation part 124. Specifically, a screwing operation part 124 is provided on the outer periphery of the water outlet surface cover 12, which is convenient for the user to operate and realize manual descaling.

[0117] In this embodiment, the switching between water discharge from the first water outlet 122 and water discharge from the second water outlet 121 is achieved by rotating the water outlet assembly 1. Specifically, when the water outlet assembly 1 is rotated, one of the second water diversion hole and the first water diversion hole on the water diversion member communicates with the water inlet channel 42, allowing water to flow from the second water outlet 121 through the second water channel 10, or from the first water outlet 122 through the first water channel 20.

[0118] In this embodiment, see Figure 5 , the housing 4 is provided with an elastic positioning component 6, see Figure 11The water outlet assembly 1 is provided with a plurality of engaging portions 117 on the side facing the housing 4. When the water outlet assembly 1 is rotated relative to the housing 4 by screwing the operating portion 124, the elastic positioning assembly 6 slides with the water outlet assembly 1 and can sequentially and detachably engage with the plurality of engaging portions 117. The plurality of engaging portions 117 correspond to a first mode in which the water inlet channel 42 is connected to the first water outlet hole 122, a second mode in which the water inlet channel 42 is connected to the second water outlet hole 121, and a third mode in which the descaling rack 22 is manually moved away from the first water outlet hole 122. By rotating the water outlet assembly 1, the elastic positioning assembly 6 can sequentially engage with the plurality of engaging portions 117 to position the water outlet assembly 1 in a position in which the water inlet channel 42 is connected to the first water outlet hole 122 (i.e., the first mode), or in a position in which the water inlet channel 42 is connected to the second water outlet hole 121 (i.e., the second mode), or to position the descaling needle 222 away from the first water outlet hole 122 (i.e., the third mode). When the elastic positioning component 6 is engaged with different engaging portions 117, the water outlet component 1 is positioned in different water outlet modes. When the water outlet component 1 is manually rotated, the water outlet component 1 is first switched to the third mode and then to other modes, manual descaling can be achieved.

[0119] At the moment when the elastic positioning component 6 is engaged with the engaging portion 117 , tactile feedback can be given to the user through vibration, so that the user knows that the water outlet component 1 has switched to a certain water outlet mode.

[0120] Specifically, the elastic positioning assembly 6 includes a bumping ball 61 and an elastic member 62, see Figure 12 and Figure 13 The housing 4 has a protruding mounting tube 43, into which the ball 61 and the elastic member 62 are mounted. The ball 61 expands and contracts under the elastic force of the elastic member 62 to engage or disengage with the engaging portion 117. The engaging portion 117 is a snap-fit groove provided on the water diverter 11, and the top end of the ball 61 engages with or disengages from the snap-fit groove.

[0121] Exemplarily, the elastic member 62 is a spring.

[0122] In this embodiment, the diameter of the second water outlet hole 121 is larger than the diameter of the first water outlet hole 122. Since only one descaling needle 222 is provided on the descaling rack 22 for each first water outlet hole 122, and the second water outlet hole 121 cannot be descaled, in order to reduce the possibility of the second water outlet hole 121 being blocked by impurities, the diameter of the second water outlet hole 121 is set to be larger than the diameter of the first water outlet hole 122, which reduces scale accumulation and is also convenient for users to clean.

[0123] Furthermore, on the water outlet surface cover 12 , a plurality of first water outlet holes 122 are arranged around the plurality of second water outlet holes 121 .

[0124] In summary, the pressurized descaling shower provided in the embodiment of the present application can automatically adjust the water spray pressure at the water outlet cover 12 when the water pressure in the water channel is low, thereby ensuring the water outlet force; at the same time, the shower has both automatic descaling and manual descaling functions, and is more practical.

[0125] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
