Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a water spray device and a toilet. Background Technology

[0002] Generally, the solubility of salts decreases as temperature rises. Modern smart toilets typically have a water heating function for personal washing. Therefore, limescale easily forms when this function is used. As limescale continuously builds up in the cleaning pipes, it can easily clog the nozzle's outlet, causing the smart toilet seat's cleaning function to fail. Utility Model Content

[0003] The main purpose of this invention is to provide a water spraying device and a toilet, which aims to prevent the cleaning components of the toilet using the water spraying device from becoming clogged during use.

[0004] To achieve the above objectives, the water spraying device proposed in this utility model includes:

[0005] Guiding components;

[0006] A spray boom assembly, movably mounted on a guide assembly, the spray boom assembly having a spray channel and at least one spray hole communicating with the spray channel; and

The descaling transmission component is drively connected to the spray bar assembly, and the descaling component is movably disposed within the spray hole.

[0008] The spray bar assembly can be driven to reciprocate along the guide assembly, and can drive the descaling component to reciprocate within the spray hole via the descaling transmission component.

[0009] In one embodiment, the spray bar assembly includes a spray bar and a nozzle disposed at one end of the spray bar. The spray bar is movably mounted on the guide assembly to drive the nozzle closer to or further away from the guide assembly. The spray bar has the spray channel, the nozzle has the spray hole, and the nozzle has a spray cavity that connects the spray channel and the nozzle.

[0010] In one embodiment, the descaling component has a first position inserted into the spray hole and a second position facing the spray hole. The spray rod assembly is used to drive the descaling transmission component to move during movement, thereby driving the descaling component to move along a first direction and switch between the first and second positions.

[0011] In one embodiment, the descaling component is movably disposed within the spray chamber, the descaling component including a needle portion facing the spray hole. When the descaling component is in a first position, the needle portion is inserted into the spray hole, and when the descaling component is in a second position, the needle portion is located within the spray chamber.

[0012] In one embodiment, the descaling transmission component includes a first magnetic component and a second magnetic component. The first magnetic component is disposed on the guide assembly, and the second magnetic component is disposed on the side of the descaling component away from the nozzle. When the descaling component is in a first position, the second magnetic component faces the first magnetic component and magnetically repels the first magnetic component.

[0013] In one embodiment, the descaling component further includes a sliding component, which is slidably disposed within the spray cavity. The sliding component has the needle portion on the side facing the spray hole, and the second magnetic component is disposed on the side of the sliding component away from the spray hole.

[0014] In one embodiment, the descaling transmission component further includes a reset component disposed within the spray chamber. The reset component is connected to the descaling component and is used to drive the needle portion to move toward the spray chamber when the mutual repulsion between the second magnetic component and the first magnetic component disappears, so that the descaling component is in a second position.

[0015] In one embodiment, the reset assembly includes a first guide rod and a first spring, the descaling component is slidably disposed on the first guide rod, and the first spring is sleeved on the first guide rod and located between the descaling component and the inner wall of the spray chamber.

[0016] In one embodiment, the descaling component is disposed outside the nozzle, and the descaling component also has a third position away from the nozzle. The guide assembly is also used to drive the descaling transmission component to move during movement, so as to drive the descaling component to move along the second direction and switch positions between the second position and the third position, wherein the first direction and the second direction are arranged intersectingly.

[0017] In one embodiment, the descaling transmission component includes a mounting component movably disposed on the guide assembly along a second direction. The mounting component is provided with the descaling component, and the nozzle is used to abut against the mounting component and position itself when moving toward the guide assembly, so that the descaling component is in a second position.

[0018] In one embodiment, the nozzle has a protrusion on the side away from the spray bar, and the protrusion abuts against the mounting member.

[0019] In one embodiment, the guiding assembly includes a guide member and a fixing member disposed on the guide member, the fixing member and the guide member enclosing a channel for the movement of the nozzle, and the mounting member being movably disposed in the channel along a second direction;

[0020] The descaling transmission component also includes a pressing component, which is located on the side of the fixing component facing the guide component. When the descaling component is in the second position and moves toward the channel with the nozzle, the pressing component is used to drive the descaling component to insert into the spray hole so that the descaling component is in the first position.

[0021] In one embodiment, the descaling component includes a needle and an elastic portion connected to each other, the needle facing the nozzle, and the pressing component pressing the elastic portion to drive the needle into the nozzle.

[0022] In one embodiment, the pressing member is provided with a guide slope, one end of which is connected to the fixing member and faces the descaling member, and the other end of which is connected to the side of the pressing member away from the fixing member.

[0023] In one embodiment, the descaling transmission component further includes an elastic element that connects the mounting component and the guide assembly. The elastic element is used to store force when the nozzle moves toward the guide assembly and to release force when the nozzle moves away from the guide assembly, so as to drive the mounting component to move away from the guide assembly.

[0024] In one embodiment, the elastic element includes a second guide rod and a second spring. The second guide rod is disposed on the guide assembly. The mounting member is slidably disposed on the second guide rod along a second direction. The two ends of the second guide rod are respectively provided with fixed seats that limit the movement of the mounting member. The second spring is sleeved on the second guide rod and located between the mounting member and one of the fixed seats.

[0025] In one embodiment, the nozzle is provided with two spray holes and two spray chambers are provided inside the nozzle. The two spray holes and the two spray chambers are connected one-to-one. The descaling component is provided with two components and is arranged corresponding to the two spray holes.

[0026] This utility model also proposes a toilet, including a toilet body and a water spray device as described above.

[0027] The technical solution of this utility model involves setting up a descaling transmission component, which is connected to at least one of the guide assembly and the spray bar assembly. When the spray bar assembly moves relative to the guide assembly, it can drive the spray bar descaling transmission component to move, enabling the descaling component, which is connected to the descaling transmission component, to move and achieve the through-feeding motion of the spray holes on the spray bar assembly. When this water spraying device is applied to a toilet, it can drive the descaling component to move when the spray bar assembly finishes spraying water and retracts along the guide assembly, thus mechanically descaling the spray holes. This can prevent the spray holes from becoming clogged during long-term use, thereby avoiding the problem of the toilet's cleaning function failing due to clogging of the cleaning components during use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0055] Generally, the solubility of salts decreases as temperature rises. Modern smart toilets typically have a water heating function for personal washing. Therefore, limescale easily forms when this function is used. As limescale continuously builds up in the cleaning pipes, it can easily clog the nozzle's outlet, causing the smart toilet seat's cleaning function to fail.

[0056] To address the aforementioned issues, existing technology has developed a toilet spray bar device with descaling function. The descaling component includes 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 mounted on the mounting part, and the other end of the descaling needle passes through a through hole in the nozzle body and extends into the water passage cavity, and can be inserted into the water outlet. The descaling needle and the through hole are sealed together. As the spray bar extends and retracts, the mounting part causes the descaling needle to move through the water outlet of the nozzle, thereby achieving mechanical descaling of the nozzle.

[0057] However, this descaling method has the following drawbacks: 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 through the internal pipe of the nozzle into the water spray hole. This requires a seal between the through hole and the descaling needle. Moreover, with the increase of the number of uses, the seal will suffer friction failure or aging failure, causing the nozzle to leak water downwards, resulting in insufficient cleaning water pressure.

[0058] This utility model proposes a water spraying device 100. Its purpose is to remove scale from the nozzle spray holes, preventing blockage that could cause the toilet's cleaning function to fail.

[0059] Please see Figures 1 to 20In one embodiment of this utility model, the water spraying device 100 includes a guide assembly 10, a spray bar assembly 20, and a descaling assembly 30. The spray bar assembly 20 is movably mounted on the guide assembly 10. The spray bar assembly 20 has a spray channel 201 and at least one spray hole 202 communicating with the spray channel 201. The descaling assembly 30 includes a descaling component 31 and a descaling transmission component 32 that is pulsatically connected to the descaling component 31. The descaling transmission component 32 is pulsatically connected to the spray bar assembly 20. The descaling component 31 is movably disposed within the spray hole 202. The spray bar assembly 20 can be driven to reciprocate along the guide assembly 10 and can drive the descaling component 31 to reciprocate within the spray hole 202 via the descaling transmission component 32.

[0060] This invention also includes a spray bar drive component, which drives the spray bar assembly 20 to move along the guide assembly 10. When the water spraying device 100 of this invention is applied to a toilet and assembled on the toilet body, the spray bar drive component can drive the spray bar assembly 20 to extend along the guide assembly 10. Water enters through the spray channel 201 of the spray bar assembly 20 and is then sprayed out through the spray hole 202 to clean the buttocks. When the spray bar assembly 20 retracts along the guide assembly 10, it can drive the descaling transmission component 32 to move. The movement of the descaling transmission component 32 drives the descaling component 31 to move and insert into the spray hole 202. After water is sprayed from the spray hole, the dirt adhering to the periphery of the spray hole 202 is removed by mechanical insertion. When the spray bar drive unit drives the spray bar assembly 20 to extend along the guide assembly 10 again, the spray bar assembly 20 continues to drive the descaling transmission component 32 to move, causing the descaling component 31 to move and be pulled out of the spray hole 202, completing the reciprocating insertion and withdrawal movement of the spray hole 202. Alternatively, in other embodiments, when the spray bar drive unit drives the spray bar assembly 20 to extend along the guide assembly 10, the spray bar assembly 20 can drive the descaling transmission component 32 to move, thereby driving the descaling component 31 to move, insert into the spray hole 202, and then pull out of the spray hole 202 to achieve descaling and cleaning of the spray hole 202. Alternatively, when the spray bar assembly 20 extends and retracts along the guide assembly 10, it can drive the descaling component 31 to move, insert into the spray hole 202, and then pull out of the spray hole 202 to perform descaling and cleaning. This utility model does not make specific limitations.

[0061] The descaling component 31 can be disposed in the spray chamber 203 of the spray bar assembly 20, which is connected to the spray channel 201. A part of the descaling transmission component 32 can be disposed on the descaling component 31, and the other part of the descaling transmission component 32 can be disposed on the guide assembly 10. When the guide assembly 10 moves along the spray bar assembly 20, a part of the descaling transmission component 32 and the other part can move relative to each other. When a part of the descaling transmission component 32 approaches the other part, it can apply a force to the other part, so that the other part of the descaling transmission component 32 can drive the descaling component 31 to move toward the spray hole 202, penetrate the spray hole 202, and remove the deposits attached to the inner wall of the spray hole 202, thereby achieving descaling. For example, a portion of the descaling component 31 may be configured as a first magnetic component 321, and another portion of the descaling component 31 may be configured as a second magnetic component. When the spray bar assembly 20 moves, causing the first magnetic component 321 to move, the first magnetic component 321 may move toward the second magnetic component when the spray bar assembly 20 moves to a designated position. The second magnetic component may apply a magnetic repulsive force to the first magnetic component 321, causing the first magnetic component 321 to move toward a direction away from the second magnetic component, thereby driving the descaling component 31 to move toward the spray hole 202 to insert into the spray hole 202 and remove the deposits attached to the inner wall of the spray hole 202, thus achieving descaling.

[0062] Alternatively, the descaling transmission component 32 can be disposed on the guide assembly 10, and the descaling component 31 can be disposed on the outside of the spray bar assembly 20 and located on a part of the descaling transmission component 32. When the spray bar assembly 20 moves along the guide assembly 10, a part of the descaling transmission component 32 disposed on the guide assembly 10 can be positioned on the spray bar assembly 20, so that the descaling component 31 can move toward the spray hole 202 of the spray bar assembly 20. When the spray bar assembly 20 continues to move along the guide assembly 10, it can drive a part of the descaling transmission component 32 positioned thereon to move. When the spray bar assembly 20 moves to a preset position on the guide assembly 10, the descaling component 31 can move relative to another part of the descaling transmission component 32 on the guide assembly 10, so that the other part of the descaling transmission component 32 can drive the descaling component 31 to move toward the spray hole 202 and penetrate the spray hole 202 to achieve descaling. For example, a portion of the descaling transmission component 32 can be a mounting component 324 slidably mounted on the guide assembly 10, and the movement direction of the mounting component 324 can be consistent with the movement direction of the spray bar assembly 20. Another portion of the descaling transmission component 32 can be a pressing component 325 fixedly mounted on the guide assembly 10. The pressing component 325 is located on the side of the descaling component 31 away from the spray hole 202. When the descaling component 31 moves to the position between the pressing component 325 and the spray hole 202, the pressing component 325 can press the descaling component 31, causing the descaling component 31 to move toward the spray hole 202, thereby achieving descaling through the spray hole 202.

[0063] The technical solution of this utility model is to set up a descaling transmission component 32, which is connected to at least one of the guide component 10 and the spray rod assembly 20. When the spray rod assembly 20 moves relative to the guide component 10, it can drive the spray rod descaling transmission component 32 to move, so that the descaling component 31 connected to the descaling transmission component 32 can move, realizing the insertion and removal movement of the spray hole 202 on the spray rod assembly 20. When the water spraying device 100 is applied to a toilet, when the spray rod assembly 20 finishes spraying water and moves back along the guide component 10, it can drive the descaling component 31 to move, and mechanically descaling the spray hole 202 by reciprocating insertion and removal. This can prevent the spray hole 202 from becoming blocked during long-term use of the water spraying device 100, thereby avoiding the problem of the cleaning component becoming blocked and the toilet cleaning function failing during use.

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

[0065] The spray bar 21 is used to introduce water into the spray chamber 203 inside the nozzle 22 through the spray channel 201. The nozzle 22 may include a nozzle housing 222 and a nozzle body 221. The nozzle body 221 is disposed inside the nozzle housing 222. Two spray holes 202 can be provided on the nozzle 22. Two descaling components 31 can be provided and are provided corresponding to the two spray holes 202. The spray chambers 203 inside the nozzle 22 can also be set as two independent sets. The two sets of spray chambers 203 can each be provided with independent water inlet holes 204, which are connected to the spray 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 practical applications, one of the spray holes 202 can be set as a posterior wash spray hole 202 and the other spray hole 202 can be set as a feminine wash spray hole 202. The posterior wash spray hole 202 and the feminine wash spray hole 202 can be used independently to clean different parts of the human body.

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

[0067] This configuration allows the descaling component 31 to switch positions between the first and second positions to descale the nozzle 202. The descaling component 31 can move linearly, simplifying the method of driving its movement. This also simplifies the design of the spray bar assembly 20, which in turn moves the descaling transmission component 32 to drive the descaling component 31, further reducing the design cost of the water spraying device 100. The first direction can be the direction of water spray from the nozzle 202; when the water spraying device 100 sprays water upwards, the first direction can be vertical.

[0068] The following describes how the descaling component 31 is installed within the spray chamber 203 of the spray bar assembly 20. (See reference...) Figures 2 to 7 As shown, the descaling component 31 is movably disposed within the spray cavity 203. The descaling component 31 includes a needle portion 311 facing the spray hole 202. When the descaling component 31 is in the first position, the needle portion 311 is inserted into the spray hole 202. When the descaling component 31 is in the second position, the needle portion 311 is located within the spray cavity 203.

[0069] This design eliminates the need for an additional through-hole on the nozzle 22 to install the descaling component 31 into the spray chamber 203. When the descaling component 31 is driven to move, it does not need to reciprocate through the spray hole 202 by moving along the through-hole. This ensures that the nozzle 22 has only one opening communicating with the external environment, preventing wear between the descaling component 31 and the through-hole during movement and thus avoiding leakage. Furthermore, the descaling component 31 has a needle portion 311 facing the spray hole 202. When the descaling component 31 moves towards the spray hole 202, the needle portion 311 moves towards the spray hole 202 as well. This facilitates reciprocating insertion and removal of scale through the needle portion 311 during the linear movement of the descaling component 31.

[0070] See Figure 4 , Figure 5 , Figure 6As shown, in one embodiment, the descaling transmission component 32 includes a first magnetic component 321 and a second magnetic component 322. The first magnetic component 321 is disposed on the guide assembly 10, and the second magnetic component 322 is disposed on the side of the descaling component 31 away from the nozzle 202. When the descaling component 31 is in the first position, the second magnetic component 322 faces the first magnetic component 321 and magnetically repels the first magnetic component 321.

[0071] Both the first magnetic element 321 and the second magnetic element 322 are made of magnetic materials. When the first magnetic element 321 faces the second magnetic element 322, the first magnetic element 321 and the second magnetic element 322 can be arranged opposite each other. The magnetic poles on the opposite sides of the first magnetic element 321 and the second magnetic element 322 are the same, for example, both are S poles or both are N poles. Since the first magnetic element 321 is located on the guide assembly 10, the guide assembly 10 is relatively fixed, while the second magnetic assembly is located on the side of the descaling element 31 away from the spray hole 202. The descaling element 31 is movably arranged in the spray cavity 203. Therefore, when When the spray bar assembly 20 moves, it causes the second magnetic element 322 located in the spray cavity 203 to move toward the first magnetic element 321. Under the action of magnetic repulsion, the second magnetic element 322 can drive the descaling element 31 toward the spray hole 202 and insert it into the spray hole 202 for descaling and cleaning. When the spray bar assembly 20 continues to move, and the second magnetic element 322 is no longer toward the first magnetic element 321, the magnetic repulsion between the second magnetic element 322 and the first magnetic element 321 disappears, and the descaling element 31 falls back into the spray cavity 203, causing the needle 311 to be pulled out from the spray hole 202.

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

[0073] With this configuration, the movement of the needle 311 can be guided by the sliding of the slider 312 within the spray cavity 203. Furthermore, the second magnetic element 322 is positioned on the side of the slider 312 away from the needle 311, resulting in fewer obstructions between the second magnetic element 322 and the first magnetic element 321. This allows the first magnetic element 321 to exert a greater magnetic repulsion force on the second magnetic element 322, ensuring the driving effect of the descaling transmission element 32 on the descaling element 31.

[0074] In the above embodiments, the connection between the needle 311 and the slider 312 can be an assembly connection, such as a snap-fit, threaded connection, or riveting connection, or the needle 311 and the slider 312 can be integrally formed. When the second magnetic component 322 is installed on the slider 312, a receiving groove can be provided on the side of the slider 312 away from the needle 311, and the second magnetic component 322 can be placed in the receiving groove. This makes the bottom of the slider 312 more integral after the second magnetic component 322 is installed. In addition, a magnet sealing cover 314 can be provided at the bottom of the slider 312 to seal the second magnetic component 322 in the receiving groove, preventing the second magnetic component 322 from being corroded and contaminated by water from the spray nozzle 202 when it is submerged in water for a long time.

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

[0076] When the water spray device 100 is mounted on the toilet at a certain angle, the descaling component 31 may not be able to fall back into the spray chamber 203 properly when it is inserted into the spray hole 202 due to its own tilt. Alternatively, there may be frictional resistance between the descaling component 31 and the spray hole 202, which may prevent the descaling component 31 from falling back properly. In this case, a reset component 323 can be installed in the spray chamber 203 for resetting the descaling component 31.

[0077] See Figure 8 , Figure 9 As shown, in one embodiment, the descaling transmission component 32 further includes a reset component 323 disposed within the spray chamber 203. The reset component 323 is connected to the descaling component 31. 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 component 322 and the first magnetic component 321 disappears, so that the descaling component 31 is in a second position. With this configuration, when the descaling component 31 is in the first position and the second magnetic component 322 is in a position not toward the first magnetic component 321, even if the setting angle of the descaling component 31 has a certain tilt, or there is a certain frictional resistance between the descaling component 31 and the spray hole 202, the reset component 323 can drive the descaling component 31 back into the spray chamber 203, so that the needle 311 is away from the spray hole 202.

[0078] Furthermore, when the descaling component 31 is reset to the second position by the reset assembly 323, the reset assembly 323 can also guide the movement of the descaling component 31. (See also...) Figure 8 , Figure 9 In one embodiment, the reset assembly 323 includes a first guide rod 3231 and a first spring 3232. The descaling component 31 is slidably disposed on the first guide rod 3231, and the first spring 3232 is sleeved on the first guide rod 3231 and located between the descaling component 31 and the inner wall of the spray chamber 203.

[0079] This configuration allows the descaling component 31 to be guided by the first guide rod 3231 when it moves from the first position to the second position. This prevents the descaling component 31 from failing to return to the designated position when it falls back into the spray chamber 203. Furthermore, when the descaling component 31 moves from the second position to the first position, it can also be guided by the first guide rod 3231. This allows the descaling component 31 to be driven by magnetic repulsion, enabling the needle 311 to be accurately inserted into the spray hole 202. This prevents the descaling component 31 from shifting when it moves toward the second position, which would cause the needle 311 of the descaling component 31 to interfere with the inner wall of the spray chamber 203 and prevent it from being accurately inserted into the spray hole 202.

[0080] Regarding the arrangement of the first spring 3232 on the first guide rod 3231, one end of the first spring 3232 may abut against the inner wall of the spray cavity 203 near the spray hole 202, and the other end of the first spring 3232 may abut against the side of the descaling component 31 near the spray hole 202. Alternatively, one end of the first spring 3232 may abut against the inner wall of the spray cavity 203 away from the spray hole 202, and the other end of the first spring 3232 may abut against the side of the descaling component 31 away from the spray hole 202. The specific arrangement is not limited.

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

[0082] The second direction can be the direction of movement of the spray bar assembly 20. When the spray hole 202 sprays water upward, the second direction can be left or right. Thus, when the descaling component 31 is located 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. This ensures that when the nozzle 22 sprays water outward through the spray hole 202, it will not be interfered with by the descaling component 31. While achieving descaling of the spray hole 202, the situation where the descaling component 31 is located outside the nozzle 22 and interferes with the water spraying operation of the spray hole 202 is avoided.

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

[0084] The mounting component 324 can be set on the side of the nozzle 22 facing the spray bar 21. When the nozzle 22 moves towards the guide assembly 10 in the second direction, the nozzle 22 can abut against the mounting component 324. The mounting component 324 is provided with a descaling component 31. Through the abutment between the nozzle 22 and the mounting component 324, the descaling component 31 is positioned on the nozzle 22, so that the descaling component 31 can be in the second position facing the spray hole 202 on the nozzle 22.

[0085] See Figure 16 , Figure 17 As shown, in one embodiment, the nozzle 22 has a protrusion 220 on the side away from the spray bar 21, and the protrusion 220 abuts against the mounting member 324.

[0086] With this configuration, by having the protrusion 220 on the side of the nozzle 22 away from the spray bar 21 abut against the mounting member 324, the portion of the nozzle 22 near the spray bar 21 can be at least partially located below the mounting member 324, thereby allowing the descaling member 31 on the mounting member 324 to face the spray hole 202. Two protrusions 220 can be provided, each located at the junction of the two sides of the nozzle 22 along the front-rear direction with the side of the nozzle 22 away from the spray bar 21. The cross-section of the mounting member 324 can be "gate" shaped, allowing the mounting member 324 to be positioned on the nozzle 22 by abutting against the protrusions 220 on both sides.

[0087] The following describes how the descaling component 31 moves from the second position to the first position. (See attached document.) Figure 13 , Figure 14 , Figure 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. The mounting member 324 is movably disposed in the channel along a second direction.

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

[0089] Thus, by setting the fixing member 12 and the guide member 11 to form a channel, the nozzle 22 is used for reciprocating insertion and insertion movement, and the mounting member 324 is used for reciprocating insertion and insertion movement along the second direction with the nozzle 22. 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 below the pressing member 325, the pressing member 325 and the descaling member 31 can be pressed together to make the descaling member 31 move towards the spray hole 202 under the pressing action of the pressing member 325, so that it can be inserted into the spray hole 202, and the pressing member 325 can be in the first position inserted into the spray hole 202.

[0090] Continue reading Figure 13 , Figure 14 , Figure 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. The pressing member 325 is used to press the elastic portion 313 to drive the needle portion 311 into the spray hole 202.

[0091] This design allows the descaling component 31 to be elastic. When the nozzle 22 moves away from the channel, and the pressing member 325 separates from the elastic part 313 and stops pressing the elastic part 313, the elastic part 313 can reset under its own elasticity, causing the needle part 311 to be pulled out of the spray hole 202, so that the descaling component 31 returns to the second position facing the spray hole 202. Furthermore, when the nozzle 22 continues to move away from the channel, the nozzle 22 no longer abuts against the mounting member 324, and the descaling component 31 no longer faces the spray hole 202, so that the descaling component 31 is in the third position away from the nozzle 22.

[0092] In addition, to ensure that the pressing member 325 can effectively press the descaling member 31 toward the spray nozzle 202, a guide slope 3251 can be provided on the pressing member 325. (See reference...) Figure 14As shown, in one embodiment, the pressing member 325 is provided with a guide slope 3251. One end of the guide slope 3251 is connected to the fixing member 12 and faces the descaling member 31, and the other end of the guide slope 3251 is connected to the side of the pressing member 325 away from the fixing member 12.

[0093] Thus, when the nozzle 22 moves toward the channel, the descaling component 31 can contact the guide slope 3251 from the side connected to the fixing component 12. As the nozzle 22 continues to move toward the channel, the descaling component 31 can slide along the guide slope 3251 to abut against the side of the pressing component 325 facing the descaling component 31. The pressing component 325 can gradually apply a force toward the nozzle 202 to the descaling component 31. After the elastic part 313 deforms, it can push the needle part 311 to insert into the nozzle 202, removing the deposits attached to the inner wall of the nozzle 202, thereby achieving descaling of the nozzle 202.

[0094] Furthermore, when the descaling component 31 is in the first position and the nozzle 22 moves in a direction away from the channel, the descaling component 31 can also slide along the guide slope 3251 away from the fixing component 12 towards the end of the guide slope 3251 connected to the fixing component 12, so that the descaling component 31 gradually separates from the pressing component 325, thereby gradually resetting the descaling component 31 and gradually pulling the needle part 311 of the descaling component 31 out of the spray hole 202, avoiding excessive rebound force of the descaling component 31 and the phenomenon of loosening from the mounting component 324.

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

[0096] In this utility model, in addition to mechanically descaling the nozzle 202 using the descaling component 31, the nozzle 202 can also be descaled by flushing. (See reference...) Figure 14As shown, the fixing member 12 is provided with a liquid inlet channel 121, which has a flushing outlet 122 that can face the spray hole 202. With this configuration, when the nozzle 22 moves along the channel, cleaning fluid can be sprayed into the spray hole 202 when the flushing outlet 122 faces the spray hole 202, thus cleaning the spray hole 202. The spray hole 202 can be located upstream of the nozzle 22 moving towards the channel, meaning that before the descaling component 31 removes and inserts the nozzle 202 for descaling, the nozzle 202 is first cleaned through the flushing outlet 122. Alternatively, the spray hole can be located downstream of the nozzle 22 moving towards the channel, meaning that after the descaling component 31 removes and inserts the nozzle 202 for descaling, the nozzle 202 is then cleaned through the flushing outlet 122. The specific configuration is not limited.

[0097] When the descaling component 31 is in the second position and the nozzle 22 is moving away from the guide component 11 and no longer abuts against the mounting component 324, in order to allow the mounting component 324 to continue moving away from the guide component 11 and the descaling component 31 to move to the third position, an elastic element 326 can also be provided between the descaling component 31 and the guide assembly 10. (See reference...) Figure 16 , Figure 17 , Figure 18 As shown, in one embodiment, the descaling transmission component 32 further includes an elastic element 326. The elastic element 326 connects the mounting component 324 and the guide assembly 10. The elastic element 326 is used to store force when the nozzle 22 moves toward the guide assembly 10 and to release force when the nozzle 22 moves away from the guide assembly 10, thereby driving the mounting component 324 to move away from the guide assembly 10, and causing the descaling component 31 to move to the third position. Thus, when the nozzle 22 moves away from the guide assembly 11, the mounting component 324 can continue to move away from the guide assembly 11 under the elastic force of the elastic element 326.

[0098] Furthermore, the elastic element 326 can also guide the movement of the mounting element 324. (See further...) Figure 15 , Figure 16 , Figure 17 In one embodiment, the elastic element 326 includes a second guide rod 3261 and a second spring 3262. The second guide rod 3261 is disposed on the guide assembly 10. The mounting member 324 is slidably disposed on the second guide rod 3261 along a second direction. The two ends of the second guide rod 3261 are respectively provided with fixing seats 3262a that limit the movement of the mounting member 324. The second spring 3262 is sleeved on the second guide rod 3261 and located between the mounting member 324 and one of the fixing seats 3262a.

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

[0100] Alternatively, the second spring 3262 can be disposed between the mounting member 324 and the fixed seat 3262a facing the nozzle 22, and connected to both the mounting member 324 and the fixed seat 3262a. When the mounting member 324 is pushed towards the channel by the nozzle 22, the second spring 3262 elastically stretches and stores force. When the nozzle 22 moves away from the mounting member 324, the second spring 3262 contracts and releases force, pulling the mounting member 324 back to its original position. Or, when the second spring 3262 is disposed between the mounting member 324 and the fixed seat 3262a 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 towards the channel by the nozzle 22, the second spring 3262 elastically compresses and stores force. When the nozzle 22 moves away from the mounting member 324, the second spring 3262 extends and releases force, pushing the mounting member 324 back to its original position, allowing the descaling member 31 to move to the third position.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
