[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] Generally speaking, the solubility of salt substances decreases as the temperature rises. Nowadays, smart toilets generally have a water heating function for human body cleaning. Therefore, it is easy to form scale when using this function. As scale is continuously generated during the use of the cleaning pipeline, it is easy to cause the water outlet of the nozzle to be blocked, thereby causing the cleaning function of the smart cover to fail.

[0056] In order to solve the above problems, a toilet spray rod device with a descaling function has appeared in the prior art. A descaling component is provided, including a mounting part and a descaling needle. The mounting part is movably connected to the outside of the nozzle body. One end of the descaling needle is installed on the mounting part, and the other end of the descaling needle passes through the through hole provided in the nozzle body and extends into the water flow cavity, and can be inserted into the water outlet hole, and the descaling needle is sealed with the through hole; the mounting part drives the descaling needle to penetrate the water outlet hole of the nozzle as the spray rod moves in an extension and contraction manner, thereby realizing mechanical descaling of the nozzle.

[0057] However, this descaling method has the following shortcomings: the descaling needle needs to be inserted from the outside of the nozzle into the through hole of the nozzle body and into the internal pipe of the nozzle, and then inserted from the internal pipe of the nozzle into the water spray hole. This requires sealing requirements between the through hole and the descaling needle, and as the number of uses increases, the seal will fail due to friction or aging, causing water to leak downward from the nozzle, resulting in insufficient cleaning water pressure.

[0058] The present invention provides a water spray device 100, which is intended to achieve descaling of the water spray hole of the nozzle, and to prevent the water spray hole from being blocked, which may cause the cleaning function of the toilet bowl to which the water spray device 100 is applied to fail.

[0059] See also Figures 1 to 20In one embodiment of the present invention, the water spraying device 100 includes a guide assembly 10, a spray rod assembly 20 and a descaling assembly 30. The spray rod assembly 20 can be movably mounted on the guide assembly 10. The spray rod assembly 20 has an injection channel 201 and at least one spray hole 202 connected to the injection channel 201. The descaling assembly 30 includes a descaling member 31 and a descaling transmission member 32 that is transmission-connected to the descaling member 31. The descaling transmission member 32 is transmission-connected to the spray rod assembly 20. The descaling member 31 is movably disposed in the spray hole 202. The spray rod assembly 20 can be driven to reciprocate along the guide assembly 10, and can drive the descaling member 31 to reciprocate in the spray hole 202 through the descaling transmission member 32.

[0060] In the present invention, a spray rod driving member is also included. The spray rod driving member is used to drive the spray rod assembly 20 to move along the guide assembly 10. When the water spraying device 100 of the present invention is applied to a toilet and assembled on the toilet body, the spray rod driving member can drive the spray rod assembly 20 to move and extend along the guide assembly 10, and water enters through the spray channel 201 of the spray rod assembly 20, and then sprays water through the spray hole 202 to clean the buttocks of the human body. When the spray rod assembly 20 moves and retracts along the guide assembly 10, the spray rod assembly 20 can drive the descaling transmission member 32 to move. Through the movement of the descaling transmission member 32, the descaling member 31 is driven to move and insert into the spray hole 202. After the spray hole sprays water, the dirt attached to the periphery of the spray hole 202 is removed by mechanical insertion. When the spray rod driving member drives the spray rod assembly 20 to move and extend along the guide assembly 10 again, the spray rod assembly 20 continues to drive the descaling transmission member 32 to move, drive the descaling member 31 to move, and withdraw from the spray hole 202, completing the reciprocating interlacing movement of the spray hole 202. Alternatively, in other embodiments, when the spray rod driving member drives the spray rod assembly 20 to move and extend along the guide assembly 10, the spray rod assembly 20 can drive the descaling transmission member 32 to move, and then drive the descaling member 31 to move, insert into the spray hole 202, and then withdraw from the spray hole 202, so as to achieve descaling and cleaning of the spray hole 202, or when the spray rod assembly 20 moves and extends and retracts along the guide assembly 10, it drives the descaling member 31 to move, insert into the spray hole 202, and then withdraw from the spray hole 202, so as to perform descaling and cleaning, which is not specifically limited in the present invention.

[0061] Among them, the descaling member 31 can be arranged in the spray chamber 203 of the spray rod assembly 20, the spray chamber 203 is connected to the injection channel 201, a part of the descaling transmission member 32 can be arranged on the descaling member 31, and the other part of the descaling transmission member 32 can be arranged on the guide assembly 10. When the guide assembly 10 moves along the spray rod assembly 20, one part of the descaling transmission member 32 and the other part can move relative to each other. When one part of the descaling transmission member 32 approaches the other part thereof, a force can be applied to the other part, so that the other part of the descaling transmission member 32 can drive the descaling member 31 to move toward the spray hole 202, penetrate the spray hole 202, remove the sediment attached to the inner wall of the spray hole 202, and achieve descaling. Exemplarily, a part of the descaling component 31 can be set as a first magnetic component 321, and the other part of the descaling component 31 can be set as a second magnetic component. When the spray rod assembly 20 moves and drives the first magnetic component 321 to move, the first magnetic component 321 can be oriented toward the second magnetic component when the spray rod assembly 20 moves to a specified position. The second magnetic component can exert a magnetic repulsive force on the first magnetic component 321, so that the first magnetic component 321 moves in a direction away from the second magnetic component, driving the descaling component 31 to move toward the spray hole 202 to insert into the spray hole 202, thereby removing the sediment attached to the inner wall of the spray hole 202 and achieving descaling.

[0062] Alternatively, the descaling transmission member 32 can be provided on the guide assembly 10, and the descaling member 31 can be provided on the outside of the spray rod assembly 20 and located on a portion of the descaling transmission member 32. When the spray rod assembly 20 moves along the guide assembly 10, a portion of the descaling transmission member 32 provided on the guide assembly 10 can be positioned on the spray rod assembly 20, so that the descaling member 31 can be directed toward the spray hole 202 of the spray rod assembly 20. When the spray rod assembly 20 continues to move along the guide assembly 10, it can drive a portion of the descaling transmission member 32 positioned thereon to move. When the spray rod assembly 20 moves to a preset position on the guide assembly 10, the descaling member 31 can move relative to another portion of the descaling transmission member 32 on the guide assembly 10, so that the other portion of the descaling transmission member 32 can drive the descaling member 31 to move toward the spray hole 202, and descaling is achieved by interspersing the spray hole 202. Exemplarily, a part of the descaling transmission member 32 can be a mounting member 324 slidably mounted on the guide assembly 10, and the movement direction of the mounting member 324 can be consistent with the movement direction of the spray rod assembly 20. Another part of the descaling transmission member 32 can be a pressing member 325 fixedly arranged on the guide assembly 10. The pressing member 325 is located on the side of the descaling member 31 away from the spray hole 202. When the descaling member 31 moves to a position between the pressing member 325 and the spray hole 202, the pressing member 325 can press the descaling member 31 to move the descaling member 31 toward the spray hole 202, thereby realizing descaling through the spray hole 202.

[0063] The technical solution of the present invention is to set a descaling transmission member 32, which is connected to at least one of the guide assembly 10 and the spray rod assembly 20. When the spray rod assembly 20 moves relative to the guide assembly 10, it can drive the spray rod descaling transmission member 32 to move, so that the descaling member 31 connected to the descaling transmission member 32 can move, and the spray hole 202 on the spray rod assembly 20 can be plugged in and out. When the water spraying device 100 is applied to a toilet, when the spray rod assembly 20 finishes spraying water and moves and retracts along the guide assembly 10, it can drive the descaling member 31 to move, and mechanically descaling the spray hole 202 by reciprocating. In this way, the spray hole 202 of the water spraying device 100 can be prevented from being blocked when the water spraying device 100 is used for a long time, thereby avoiding the problem that the cleaning components of the toilet using the water spraying device 100 are blocked during use, causing the cleaning function of the toilet to fail.

[0064] See also Figure 3 , Figure 4 , Figure 7 As shown, in one embodiment, the spray rod assembly 20 includes a spray rod 21 and a nozzle 22 disposed at one end of the spray rod 21, the spray rod 21 can be movably mounted on the guide assembly 10 to drive the nozzle 22 to approach or move away from the guide assembly 10, the spray rod 21 is provided with the injection channel 201, the nozzle 22 is provided with the spray hole 202, the nozzle 22 is provided with a spray cavity 203, and the spray cavity 203 connects the injection channel 201 and the nozzle 22.

[0065] Among them, the spray rod 21 is used to let water into the spray chamber 203 in the nozzle 22 through the injection channel 201. The nozzle 22 may include a nozzle housing 222 and a nozzle body 221. The nozzle body 221 is arranged in the nozzle housing 222. Two spray holes 202 arranged on the nozzle 22 can be set, and two descaling parts 31 can be set and corresponding to the two spray holes 202. The spray chamber 203 arranged in the nozzle 22 can also be set as two independent groups. The two groups of spray chambers 203 can be respectively provided with independent water inlet holes 204, which are connected to the injection channel 201. Each water inlet hole 204 can be provided with a switch valve to control the opening and closing of the water inlet hole 204. In actual application, one of the spray holes 202 can be set as a buttocks washing spray hole 202, and the other spray hole 202 can be set as a women's washing spray hole 202. The buttocks washing spray hole 202 and the women's washing spray hole 202 can be used independently to clean different parts of the human body.

[0066] See also Figure 5 , Fig. 20As shown, in one embodiment, the descaling member 31 has a first position inserted into the spray hole 202 and a second position facing the spray hole 202, and the spray rod assembly 20 is used to drive the descaling transmission member 32 to move during movement, so as to drive the descaling member 31 to move along the first direction and switch between the first position and the second position.

[0067] In this arrangement, the descaling member 31 can be switched between the first position and the second position to descale the spray hole 202. The descaling member 31 can be implemented in a linear motion, making the method of driving the descaling member 31 to move simpler. In this way, when the spray bar assembly 20 is designed to move to drive the descaling transmission member 32 to move, the descaling transmission member 32 can be driven to move, and the design cost of the water spray device 100 of the present invention is lower. The first direction can be the direction of the spray hole 202 spraying. When the water spray device 100 of the present invention sprays water upward, the first direction can be the up and down direction.

[0068] The following is an introduction to the method of arranging the descaling member 31 in the spray chamber 203 of the spray bar assembly 20. Figures 2 to 7 As shown, the descaling member 31 is movably disposed in the spray chamber 203, and the descaling member 31 includes a needle portion 311 facing the spray hole 202. When the descaling member 31 is in a first position, the needle portion 311 is inserted into the spray hole 202. When the descaling member 31 is in a second position, the needle portion 311 is located in the spray chamber 203.

[0069] Such a configuration makes it unnecessary to set an additional through hole on the nozzle 22 for installing the descaling member 31 from the through hole into the spray chamber 203. When the descaling member 31 is driven to move, it is unnecessary to drive the descaling member 31 to move along the through hole to reciprocate the spray hole 202, so that the nozzle 22 has only one hole connected to the external environment, which can avoid the descaling member 31 and the through hole being worn when the descaling member 31 is driven to move, causing leakage from the through hole. In addition, the descaling member 31 is provided with a needle portion 311 facing the spray hole 202, so that when the descaling member 31 is driven to move toward the spray hole 202, the needle portion 311 can be driven to move toward the spray hole 202, so that when the descaling member 31 moves linearly, it is convenient to reciprocate the spray hole 202 through the needle portion 311 to achieve descaling.

[0070] See also Figure 4 , Figure 5 , Figure 6As shown, in one embodiment, the descaling transmission member 32 includes a first magnetic member 321 and a second magnetic member 322, the first magnetic member 321 is arranged on the guide assembly 10, and the second magnetic member 322 is arranged on the side of the descaling member 31 away from the spray hole 202, when the descaling member 31 is in the first position, the second magnetic member 322 faces the first magnetic member 321, and magnetically repels the first magnetic member 321.

[0071] Among them, the first magnetic member 321 and the second magnetic member 322 are both magnetic materials. When the first magnetic member 321 faces the second magnetic member 322, the first magnetic member 321 and the second magnetic member 322 can be arranged relative to each other. The first magnetic member 321 and the second magnetic member 322 have the same magnetic poles on one side that are arranged relative to each other, for example, the same S pole or the same N pole. Since the first magnetic member 321 is arranged on the guide component 10, the guide component 10 is relatively fixed, and the second magnetic component is arranged on the side of the descaling member 31 away from the spray hole 202, the descaling member 31 can be movably arranged in the spray chamber 203. Therefore, when When the spray rod assembly 20 moves, driving the second magnetic component 322 located in the spray chamber 203 to move toward the first magnetic component 321, under the action of the magnetic repulsive force, the second magnetic component 322 can drive the descaling component 31 to move toward the spray hole 202 and insert it into the spray hole 202 for descaling and cleaning. When the spray rod assembly 20 continues to move, so that the second magnetic component 322 is no longer facing the first magnetic component 321, the magnetic repulsive force between the second magnetic component 322 and the first magnetic component 321 disappears, and the descaling component 31 falls back into the spray chamber 203, so that the needle portion 311 is pulled out of the spray hole 202.

[0072] Continue reading Figure 4 , Figure 5 , Figure 6 In one embodiment, the descaling member 31 further includes a sliding member 312, which is slidably disposed in the spray chamber 203, and the needle portion 311 is disposed on the side of the sliding member 312 facing the spray hole 202, and the second magnetic member 322 is disposed on the side of the sliding member 312 away from the spray hole 202.

[0073] With such arrangement, the movement of the needle portion 311 can be guided by the sliding of the sliding member 312 in the spray chamber 203, and the second magnetic member 322 is arranged on the side of the sliding member 312 away from the needle portion 311, so that there are fewer obstructions between the second magnetic member 322 and the first magnetic member 321, and the first magnetic member 321 can exert a greater magnetic repulsive force on the second magnetic member 322, thereby ensuring the driving effect of the descaling transmission member 32 on the descaling member 31.

[0074] In the above-mentioned embodiment, the connection between the needle portion 311 and the sliding member 312 may be an assembled connection, such as a connection method such as a snap connection, a threaded connection, a riveting connection, or the needle portion 311 and the sliding member 312 may be integrally formed. When the sliding member 312 is provided to install the second magnetic member 322, a receiving groove may be provided on the side of the sliding member 312 away from the needle portion 311, and the second magnetic member 322 may be provided in the receiving groove, so that after the second magnetic member 322 is installed, the bottom of the sliding member 312 has better integrity, and a magnet sealing cover 314 may be provided at the bottom of the sliding member 312 to seal the second magnetic member 322 in the receiving groove to prevent the second magnetic member 322 from being in the water for a long time and being corroded and contaminating the water outlet of the spray hole 202.

[0075] When the water spray device 100 of the present invention is actually assembled on a toilet, the spray hole 202 of the spray rod assembly 20 can be set upward to achieve water spraying and cleaning towards the buttocks of the human body. In this way, when the second magnetic part 322 is in a position not facing the first magnetic part 321, the descaling part 31 can fall back into the spray chamber 203 under the action of its own gravity to achieve resetting.

[0076] When the water spray device 100 is installed on the toilet and is tilted at a certain angle, the descaling component 31 may not be able to fall back into the spray chamber 203 when inserted into the spray hole 202 due to its own tilted state, or there is friction resistance between the descaling component 31 and the spray hole 202, resulting in the descaling component 31 not being able to fall back well. In this case, a reset component 323 may be provided in the spray chamber 203 to reset the descaling component 31.

[0077] See also Figure 8 , Fig. 9 As shown, in one embodiment, the descaling transmission member 32 further includes a reset component 323 disposed in the spray chamber 203, the reset component 323 is connected to the descaling member 31, and the reset component 323 is used to drive the needle 311 to move toward the spray chamber 203 when the mutual repulsion between the second magnetic member 322 and the first magnetic member 321 disappears, so that the descaling member 31 is in the second position. In this way, when the descaling member 31 is in the first position and the second magnetic member 322 is in a position not facing the first magnetic member 321, even if the setting angle of the descaling member 31 is tilted to a certain extent, or there is a certain friction resistance between the descaling member 31 and the spray hole 202, the descaling member 31 can be driven back to the spray chamber 203 by the reset component 323, so that the needle 311 is away from the spray hole 202.

[0078] In addition, when the descaling member 31 is reset to the second position by the reset assembly 323, the descaling member 31 can also be guided to move by the reset assembly 323. Figure 8 , Fig. 9 In one embodiment, the reset assembly 323 includes a first guide rod 3231 and a first spring 3232, the descaling member 31 is slidably disposed on the first guide rod 3231, the first spring 3232 is sleeved on the first guide rod 3231, and is located between the descaling member 31 and the inner wall of the spray chamber 203.

[0079] By such arrangement, when the descaling member 31 moves from the first position to the second position, it can also be guided by the first guide rod 3231 for movement, so as to prevent the descaling member 31 from being unable to return to the designated position when the descaling member 31 falls back into the spray chamber 203, and when the descaling member 31 moves from the second position to the first position, it can also be guided by the first guide rod 3231, so that the descaling member 31 can accurately insert the needle portion 311 into the spray hole 202 under the drive of the magnetic repulsive force, so as to prevent the descaling member 31 from deviating when moving toward the second position, causing the needle portion 311 of the descaling member 31 to interfere with the inner wall of the spray chamber 203 and fail to accurately insert into the spray hole 202.

[0080] Regarding the setting of the first spring 3232 on the first guide rod 3231, one end of the first spring 3232 can be in contact with the inner wall of the spray chamber 203 on the side close to the spray hole 202, and the other end of the first spring 3232 can be in contact with the side of the descaling component 31 close to the spray hole 202. Alternatively, one end of the first spring 3232 can be in contact with the inner wall of the spray chamber 203 on the side away from the spray hole 202, and the other end of the first spring 3232 can be in contact with the side of the descaling component 31 away from the spray hole 202. There is no specific limitation.

[0081] The following describes how the descaling member 31 is disposed outside the spray chamber 203 of the spray bar assembly 20. Figures 10 to 20 As shown, the descaling member 31 is arranged outside the nozzle 22, and the descaling member 31 also has a third position away from the nozzle 22. The guide assembly 10 is also used to drive the descaling transmission member 32 to move during movement, so as to drive the descaling member 31 to move along the second direction and switch positions between the second position and the third position, wherein the second direction is arranged crosswise with the first direction.

[0082] Among them, the second direction can be the movement direction of the spray rod assembly 20. When the spray hole 202 sprays water upward, the second direction can be the left and right direction. In this way, when the descaling component 31 is arranged outside the nozzle 22, when the descaling component is in the second position, the descaling component 31 is outside the spray chamber 203 and faces the spray hole 202. When the descaling component is in the third position, the descaling component 31 can be in a state away from the nozzle 22 and not facing the spray hole 202, so that when the nozzle 22 sprays water outward through the spray hole 202, it will not be interfered by the descaling component 31. While achieving descaling of the spray hole 202, it avoids the situation where the descaling component 31 is arranged outside the nozzle 22, which interferes with the water spraying work of the spray hole 202.

[0083] See also Fig.13 , Fig.16 , Fig.17 As shown, in one embodiment, the descaling transmission member 32 includes a mounting member 324, the mounting member 324 is disposed on the guide assembly 10, the mounting member 324 is provided with the descaling member 31, and the nozzle 22 is used to abut and position with the mounting member 324 when moving toward the guide assembly 10, so that the descaling member 31 is in the second position.

[0084] Among them, the mounting member 324 can be arranged on the side of the nozzle 22 facing the spray rod 21. When the nozzle 22 moves along the second direction toward the guide assembly 10, the nozzle 22 can abut against the mounting member 324, and the mounting member 324 is provided with a descaling member 31. Through the abutment between the nozzle 22 and the mounting member 324, the descaling member 31 is positioned on the nozzle 22, so that the descaling member 31 can be in the second position facing the spray hole 202 on the nozzle 22.

[0085] See also Fig.16 , Fig.17 As shown, in one embodiment, a convex portion 220 is provided on a side of the nozzle 22 away from the spray rod 21 , and the convex portion 220 is in abutment with the mounting member 324 .

[0086] In this way, by making the convex part 220 on the side of the nozzle 22 away from the spray bar 21 abut against the mounting part 324, the part of the nozzle 22 close to the spray bar 21 can be at least partially located under the mounting part 324, so that the descaling member 31 provided on the mounting part 324 can face the spray hole 202. Among them, there can be two convex parts 220, which are respectively provided at the intersection of the two sides of the nozzle 22 along the front-back direction and the side of the nozzle 22 away from the spray bar 21. The cross section of the mounting part 324 can be set to a "door" shape, and the mounting part 324 can be abutted against the convex parts 220 through the two side edges to achieve positioning on the nozzle 22.

[0087] The following describes how the descaling member 31 moves from the second position to the first position. Fig.13 , Fig.14 , Fig. 20 As shown, in one embodiment, the guide assembly 10 includes a guide member 11 and a fixing member 12 disposed on the guide member 11, the fixing member 12 and the guide member 11 enclose a channel for the nozzle 22 to move, and the mounting member 324 is movably disposed on the channel along the second direction;

[0088] The descaling transmission member 32 also includes a pressing member 325, which is arranged on the side of the fixing member 12 facing the guide member 11. When the descaling member 31 is in the second position and moves toward the channel along with the nozzle 22, the pressing member 325 is used to drive the descaling member 31 to be inserted into the spray hole 202 so that the descaling member 31 is in the first position.

[0089] In this way, a channel is formed by setting the fixing member 12 and the guide member 11 to be enclosed, which is used for the reciprocating movement of the nozzle 22 and for the mounting member 324 to reciprocate and move along the second direction with the nozzle 22, and a pressing member 325 is set on the side of the fixing member 12 facing the guide member 11. When the nozzle 22 moves into the channel and the descaling member 31 is under the pressing member 325, the pressing member 325 can be extruded with the descaling member 31 to make the descaling member 31 move toward the spray hole 202 under the extrusion of the pressing member 325, so as to be inserted into the spray hole 202, so that the pressing member 325 can be in the first position inserted into the spray hole 202.

[0090] Continue reading Fig.13 , Fig.14 , Fig. 20 In one embodiment, the descaling member 31 includes a needle portion 311 and an elastic portion 313 connected to each other, the needle portion 311 faces the spray hole 202, and the pressing member 325 is used to press the elastic portion 313 to drive the needle portion 311 to insert into the spray hole 202.

[0091] Such arrangement makes the descaling member 31 itself elastic. When the nozzle 22 moves in a direction away from the channel and the pressing member 325 separates from the elastic portion 313 and no longer presses the elastic portion 313, the elastic portion 313 can be reset under the action of its own elasticity, driving the needle portion 311 to be withdrawn from the spray hole 202, so that the descaling member 31 returns to the second position toward the spray hole 202, and when the nozzle 22 continues to move in a direction away from the channel, the nozzle 22 no longer abuts against the mounting member 324, and the descaling member 31 no longer faces the spray hole 202, so that the descaling member 31 is in the third position away from the nozzle 22.

[0092] In addition, in order to enable the pressing member 325 to effectively press the descaling member 31 toward the spray hole 202, a guiding inclined surface 3251 may be provided on the pressing member 325. Fig.14As shown, in one embodiment, the pressing member 325 is provided with a guiding slope 3251, one end of the guiding slope 3251 is connected to the fixing member 12 and faces the descaling member 31, and the other end of the guiding slope 3251 is connected to a side of the pressing member 325 away from the fixing member 12.

[0093] In this way, when the nozzle 22 moves toward the channel, the descaling member 31 can be made to contact the guide bevel 3251 from the side where the guide bevel 3251 is connected to the fixing member 12, and when the nozzle 22 continues to move toward the channel, the descaling member 31 can slide along the guide bevel 3251 until it abuts against the side of the pressing member 325 facing the descaling member 31, so that the pressing member 325 can gradually apply a force to the descaling member 31 toward the spray hole 202, so that the elastic part 313, after being deformed, can push the needle part 311 to insert into the spray hole 202, thereby removing the sediment attached to the inner wall of the spray hole 202, thereby achieving descaling of the spray hole 202.

[0094] Furthermore, when the descaling member 31 is in the first position and the nozzle 22 moves in a direction away from the channel, the descaling member 31 can also slide along the end of the guide slope 3251 away from the fixing member 12 toward the end of the guide slope 3251 connected to the fixing member 12, so that the descaling member 31 is gradually separated from the pressing member 325, thereby gradually restoring the descaling member 31 and gradually withdrawing the needle portion 311 of the descaling member 31 from the spray hole 202, thereby preventing the descaling member 31 from having too large a rebound force and coming loose from the mounting member 324.

[0095] In addition, the descaling component 31 may further include a mounting portion 315, and the mounting portion 315, the elastic portion 313 and the needle portion 311 are connected in sequence. When the descaling component 31 is installed on the mounting component 324, a mounting seat 3242 may be provided on the mounting component 324, and the mounting portion 315 of the descaling component 31 may be mounted and fixed on the mounting seat 3242, so that the descaling component 31 is mounted and fixed on the mounting component 324.

[0096] In the present invention, in addition to the method of mechanically descaling the spray hole 202 by using the descaling member 31, the spray hole 202 can also be flushed for descaling, see Fig.14As shown, the fixing member 12 is provided with a liquid inlet channel 121, and the liquid inlet channel 121 has a flushing water outlet 122 that can face the spray hole 202. With such a configuration, when the nozzle 22 moves along the channel, it can also spray cleaning liquid into the spray hole 202 when the flushing water outlet 122 faces the spray hole 202 to clean the spray hole 202. The spray hole 202 can be arranged upstream of the movement of the nozzle 22 toward the channel, that is, before the descaling member 31 removes scale from the spray hole 202, the spray hole 202 is first cleaned by flushing the water outlet 122, or the spray hole can be arranged downstream of the movement of the nozzle 22 toward the channel, that is, after the descaling member 31 removes scale from the spray hole 202, the spray hole 202 is cleaned by flushing the water outlet 122. The specific details are not limited.

[0097] When the descaling member 31 is in the second position and the nozzle 22 moves away from the guide member 11 and no longer abuts against the mounting member 324, in order to enable the mounting member 324 to continue to move away from the guide member 11 and enable the descaling member 31 to move to the third position, an elastic member 326 may be further provided between the descaling member 31 and the guide assembly 10. Fig.16 , Fig.17 , Fig.18 As shown, in one embodiment, the descaling transmission member 32 further includes an elastic member 326, the elastic member 326 connects the mounting member 324 and the guide assembly 10, the elastic member 326 is used to store force when the nozzle 22 moves toward the guide assembly 10, and is used to release force when the nozzle 22 moves away from the guide assembly 10, so as to drive the mounting member 324 to move in a direction away from the guide assembly 10, and drive the descaling member 31 to move to the third position. In this way, when the nozzle 22 moves in a direction away from the guide member 11, the mounting member 324 can continue to move in a direction away from the guide member 11 under the elastic force of the elastic member 326.

[0098] Furthermore, the setting of the elastic member 326 can also guide the movement of the mounting member 324. Fig.15 , Fig.16 , Fig.17 In one embodiment, the elastic member 326 includes a second guide rod 3261 and a second spring 3262, the second guide rod 3261 is arranged on the guide assembly 10, the mounting member 324 is slidably arranged on the second guide rod 3261 along the second direction, and both ends of the second guide rod 3261 are respectively provided with fixed seats 3262a for limiting the movement of the mounting member 324, and the second spring 3262 is sleeved on the second guide rod 3261 and is located between the mounting member 324 and one of the fixed seats 3262a.

[0099] In the above embodiment, a sliding seat 3241 can be set on both sides of the mounting member 324, and two second guide rods 3261 can be set, and are respectively set on both sides of the mounting member 324. The two sliding seats 3241 can be respectively slidably connected to the two second guide rods 3261, so that when the mounting member 324 moves, it can be guided by the second guide rods 3261, ensuring that the movement path of the mounting member 324 is more precise.

[0100] In addition, the second spring 3262 can be arranged between the mounting member 324 and the fixed seat 3262a on the side facing the nozzle 22, and connected to the mounting member 324 and the fixed seat 3262a respectively. When the mounting member 324 is pushed by the nozzle 22 to move toward the channel, the second spring 3262 elastically stretches and stores force. When the nozzle 22 moves in a direction away from the mounting member 324, the second spring 3262 contracts and releases force, pulling the mounting member 324 to return to its original position; or, when the second spring 3262 is arranged between the mounting member 324 and the fixed seat 3262a on the side away from the nozzle 22, the second spring 3262 may not be connected to the mounting member 324 and the fixed seat 3262a. When the mounting member 324 is pushed by the nozzle 22 to move toward the channel, the second spring 3262 elastically compresses and stores force. When the nozzle 22 moves in a direction away from the mounting member 324, the second spring 3262 stretches and releases force, pushing the mounting member 324 to return to its original position, so that the descaling member 31 can move to the third position.

[0101] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
