Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a water cup assembly and a dishwasher. Background Technology

[0002] In related technologies, dishwashers use a wash pump to increase water pressure and transmit it through pipes to the upper and lower spray arms. Water is sprayed from the upper and lower spray arms to clean dishes and then falls back to the bottom of the dishwasher. The wash pump then pumps the water back to the upper and lower spray arms, creating a continuous cycle. In this process, water needs to travel through two pipes to reach the upper and lower spray arms, requiring more water to meet the demand. To save water, some manufacturers currently use motors to drive a diverter valve to open or close the pipes of the upper or lower spray arms. However, because of the motor-driven method, matching circuitry and the motor itself are required, making dishwashers expensive. Utility Model Content

[0048] Please see Figure 2 and Figure 3 This utility model provides a water cup assembly 100, which includes a water cup 101, a top cover 102, a lever 103, and a guide structure 104. The top cover 102 and the lever 103 are disposed on the water cup 101. The top cover 102 has a first through hole 1021, and the lever 103 has a second through hole 1031. The guide structure 104 is connected to the top cover 102 and the lever 103.

[0049] The paddle 103 is movably connected to the upper cover 102. The paddle 103 has a mating position and a disengaged position. In the mating position, the paddle 103 is mated to the upper cover 102, and the first through hole 1021 and the second through hole 1031 are connected or not connected. In the disengaged position, the paddle 103 is separated from the upper cover 102.

[0050] The paddle 103 is used to move from the separation position to the contact position under the impact of water flow, and to move from the contact position to the separation position under its own weight.

[0051] The guide structure 104 is used to rotate the paddle 103 relative to the upper cover 102 when the paddle 103 moves between the engagement position and the disengagement position.

[0052] The aforementioned water cup assembly 100, through the guide structure 104, can be driven to rotate by the water flow when water is flowing through it, and driven to rotate by the gravity of the paddle 103 itself when water is not flowing through it. This allows the paddle 103 to rotate without the need for a motor, saving on the motor and related circuitry, and reducing costs to some extent.

[0053] Specifically, the water cup assembly 100 can be used with the dishwasher 1000. Please refer to... Figure 1 The dishwasher 1000 may include a washing tub, a spray arm, a heating element, a washing pump, and a water cup assembly 100.

[0054] The washing tank may have a washing chamber, and a support may be installed inside the washing chamber to support the tableware to be washed. The spray arm may be connected to a water source and the washing chamber to spray washing water into the washing chamber to clean the tableware.

[0055] The heating element can be used to heat the washing water sprayed into the washing chamber. The water cup assembly 100 can be located below the washing chamber to collect the washing water in the washing chamber, and the washing pump can send the washing water collected by the water cup assembly 100 back to the spray arm to recirculate the washing water sprayed into the washing chamber.

[0056] The water cup assembly 100 includes a water cup 101, a top cover 102, a lever 103, and a guide structure 104. The water cup 101 has a collection chamber 1012, where washing water can be collected under its own weight. A washing pump is connected to the collection chamber 1012 and the second through-hole 1031 of the lever 103, and a spray arm is connected to the first through-hole 1021 of the top cover 102. When there is washing water in the collection chamber 1012, the washing pump starts working, and the lever 103 moves from a separated position to a closed position under the impact of the water flow. When the first through-hole 1021 and the second through-hole 1031 are connected, the washing water in the collection chamber 1012 is sprayed into the washing chamber through the spray arm. The spray arm may include, but is not limited to, an upper spray arm 200, a lower spray arm 300, and a top spray arm 400.

[0057] The paddle 103 is movably connected to the upper cover 102. The paddle 103 has a mating position and a disengaged position. In the mating position, the paddle 103 is mated to the surface of the upper cover 102 facing the paddle 103, and the first through hole 1021 and the second through hole 1031 are connected or not connected. In the disengaged position, the paddle 103 is separated from the surface of the upper cover 102 facing the paddle 103.

[0058] Understandably, the guide structure 104 is used to rotate the paddle 103 relative to the upper cover 102 when the paddle 103 moves between the engaged and disengaged positions. This allows the first through hole 1021 and the second through hole 1031 to be connected or disconnected when the paddle 103 is in the engaged position. Specifically, in the vertical direction, when the first through hole 1021 and the second through hole 1031 have an overlapping portion, the first through hole 1021 and the second through hole 1031 are connected; when the first through hole 1021 and the second through hole 1031 do not have an overlapping portion, the first through hole 1021 and the second through hole 1031 are disconnected.

[0059] In one embodiment, the upper cover 102 includes two first through holes 1021, one of which communicates with the upper spray arm 200 and / or the top spray arm 400, and the other of which communicates with the lower spray arm 300.

[0060] In one implementation, please refer to Figure 1 , Figure 5 , Figure 6 The upper cover 102 includes two first through holes 1021, and the lever 103 includes one second through hole 1031. In the mating position, the lever 103 is mated with the upper cover 102, one first through hole 1021 and the second through hole 1031 are connected, and the other first through hole 1021 and the second through hole 1031 are not connected. When one first through hole 1021 of the upper cover 102 is connected to the upper spray arm 200 and / or the top spray arm 400, and the other first through hole 1021 is connected to the lower spray arm 300, the pipes of the upper spray arm 200 and / or the top spray arm 400, or the lower spray arm 300, can be opened or closed to achieve the purpose of water saving.

[0061] In some implementations, please refer to Figure 3 , Figure 5 and Figure 6 The rotation direction of the paddle 103 when it moves from the contact position to the separation position is the same as the rotation direction when it moves from the separation position to the contact position.

[0062] In the above embodiments, the complexity of the guide structure 104 can be reduced, wear can be reduced, and service life can be increased.

[0063] Specifically, when the paddle 103 moves between the contact position and the separation position, the guide structure 104 allows the paddle 103 to rotate relative to the top cover 102, that is, the direction of rotation of the paddle 103 is related to the guide structure 104.

[0064] In one embodiment, one of the upper cover 102 and the lever 103 is provided with a guide channel 1043, and the other includes a guide block 1044 disposed in the guide channel 1043. The guide channel 1043 includes an upper guide channel 1045 and a lower guide channel 1046. The upper guide channel 1045 includes an upper inclined sidewall 1048, and the lower guide channel 1046 includes a lower inclined sidewall 1049. In the circumferential direction of the upper cover 102, the upper inclined sidewall 1048 and the lower inclined sidewall 1049 have the same orientation, and the rotation direction of the lever 103 when moving from the contact position to the separation position is the same as the rotation direction when moving from the separation position to the contact position. Figures 2 to 8 In one embodiment, the upper cover 102 is provided with a guide channel 1043, and the paddle 103 includes a guide block 1044. The rotation direction of the paddle 103 is the same as the orientation of the upper inclined sidewall 1048 and the lower inclined sidewall 1049.

[0065] In some implementations, please refer to Figure 3 The surface of the paddle 103 away from the upper cover 102 is provided with blades 1032, which are used to drive the paddle 103 to rotate under the action of water flow impact force.

[0066] In the above embodiments, the rotation efficiency of the paddle 103 can be further improved.

[0067] Specifically, blades 1032 are provided on the side surface of the paddle 103 away from the top cover 102. The blades 1032 can extend radially along the paddle 103 and are circumferentially spaced. The water flow can directly contact the surface of the paddle 103 away from the top cover 102. Under the action of the blades 1032, the impact force of the water flow can be converted into a torque to drive the paddle 103 to rotate to a certain extent, thereby further enabling the paddle 103 to rotate relative to the top cover 102.

[0068] Optionally, the tilt angle and direction of the blade 1032 can be determined according to the water flow velocity, water flow direction and guide structure 104, so as to enable the paddle 103 to rotate quickly and reliably under the impact of water flow.

[0069] Optionally, the blade 1032 and the lever 103 are integrally formed, which helps to simplify the manufacturing process, enhance the structural strength of the lever 103, and to a certain extent prevent the blade 1032 from loosening or falling off due to long-term use or cleaning.

[0070] In some implementations, please refer to Figure 2 and Figure 2AThe water cup 101 is provided with a first limiting part 1011, and the upper cover 102 is provided with a second limiting part 1022. The first limiting part 1011 and the second limiting part 1022 cooperate with each other to restrict the rotation of the upper cover 102.

[0071] In the above embodiments, the upper cover 102 can be prevented from rotating or shifting due to external forces to a certain extent, thereby improving the stability of the upper cover 102.

[0072] Specifically, the first limiting part 1011 and the second limiting part 1022 can be a mutually cooperating protrusion and groove structure, a stop and slot structure, or other mechanical limiting and cooperating structure. After the top cover 102 is installed on the water cup 101, the first limiting part 1011 and the second limiting part 1022 can, to a certain extent, prevent the top cover 102 from being driven by the rotation of the lever 103, thereby ensuring to a certain extent that the lever 103 moves to the correct fitting position.

[0073] exist Figure 2 and Figure 2A In the embodiment, the first limiting part 1011 is a limiting notch provided on the edge of the water cup 101, and the second limiting part 1022 is a limiting protrusion provided on the edge of the upper cover 102. The limiting protrusion can be embedded in the limiting notch, and the limiting protrusion and the limiting notch cooperate to position the upper cover 102 to restrict its rotation.

[0074] In some implementations, please refer to Figure 2A The water cup 101 is provided with a water distribution cavity 115. The upper cover 102 includes a main body 1023. The main body 1023 and the lever 103 are located in the water distribution cavity 115. The main body 1023 is located above the lever 103. The main body 1023 has a first through hole 1021.

[0075] In the above embodiments, the stability of the top cover 102 and the paddle 103 can be improved to a certain extent.

[0076] Specifically, the main body 1023 is adapted to the size of the water distribution cavity of the water cup 101, so that the main body 1023 and the lever 103 can be accommodated together in the water distribution cavity 115.

[0077] The main body 1023 is provided with a first through hole 1021, which can communicate with the upper spray arm 200, the lower spray arm 300, and the top spray arm 400 respectively. A part of the guide structure 104 is provided on the upper cover 102, and another part can be provided on the lever 103, so that when the lever 103 moves in the vertical direction relative to the upper cover 102, it can rotate relative to the upper cover 102, thereby realizing the connection or disconnection of the first through hole 1021 or the second through hole 1031.

[0078] Understandably, the main body 1023 and the lever 103 are located within the water distribution cavity 115, which can, to some extent, prevent the top cover 102 and / or the lever 103 from shaking due to external forces. At the same time, it can, to some extent, reduce the impact of the external environment on the lever 103 and the top cover 102, thereby extending the service life of the water cup assembly 100.

[0079] In some implementations, please refer to Figure 2 and Figure 2A The upper cover 102 also includes a connecting tube 116, which protrudes from the main body 1023 on the side away from the lever 103 and is connected to at least one first through hole 1021.

[0080] In the above embodiments, the connecting pipe 116 can play a guiding role in the water flow process.

[0081] Specifically, the first through hole 1021 connected to the connecting pipe 116 can communicate with the water supply system, which includes, but is not limited to, the upper spray arm 200 and / or the top spray arm 400. The connecting pipe 116 can guide the water flow during the water transport process, allowing the water flow to be smoothly introduced into the water supply system, reducing water turbulence and flow resistance to a certain extent, and improving the stability and uniformity of water distribution, thereby helping to improve the spraying effect and washing performance.

[0082] In some embodiments, the water distribution chamber 115 is integrally formed on the water cup 101. The water cup assembly 100 includes a washing pump, the outlet of which is in communication with the water distribution chamber 115, and the washing pump is used to provide water flow impact to the lever 103.

[0083] In the above embodiment, water flow can be stably introduced into the water distribution chamber 115 and act on the lever 103, so that the lever 103 moves under the impact of the water flow.

[0084] Specifically, the water distribution chamber 115 and the water cup 101 can be integrally molded using an injection molding process, eliminating the need for additional connectors or seals and thus preventing leakage due to assembly gaps. Simultaneously, the integral molding structure allows for more precise relative positioning of the water distribution chamber 115 and the water cup 101, thereby improving the stability of the water cup assembly 100 during long-term operation. Furthermore, it simplifies manufacturing and assembly processes, reduces the number of parts, minimizes assembly errors, and enhances the reliability of the water cup assembly 100.

[0085] The outlet of the washing pump and the water distribution chamber 115 can be directly connected through a pipe or connector. When the washing pump starts, it pressurizes the water and sends it into the water distribution chamber 115, so that the water flow is evenly distributed and forms an impact force that acts on the lever 103, driving the lever 103 to move upward to fit against the main body 1023, so that the first through hole 1021 and the second through hole 1031 are connected or not connected.

[0086] When the washing pump stops running, the water flow impact disappears, and the lever 103 falls back to the position separated from the main body 1023 under the action of gravity.

[0087] In some embodiments, the paddle 103 is used to move upward under the impact of water flow to fit against the main body 1023, and to move downward under its own weight to separate from the main body 1023.

[0088] In the above embodiments, the lever 103 can be moved up and down by water flow and gravity to make the first through hole 1021 and the second through hole 1031 connected or disconnected.

[0089] Specifically, during the up-and-down movement, the paddle 103 can move closer to the main body 1023 to fit with the main body 1023, or move away from the main body 1023 to separate from the main body 1023.

[0090] When the paddle 103 is in contact with the main body 1023, the paddle 103 is in the contact position. When the paddle 103 is separated from the main body 1023, the paddle 103 is in the separated position.

[0091] In some implementations, please refer to Figure 5 and Figure 6 The inner diameter of the water distribution cavity 115, the diameter of the main body 1023, and the diameter of the pull plate 103 are equivalent.

[0092] In the above embodiments, the smoothness and reliability of the movement of the paddle 103 and the reliability of the main body 1023 can be improved.

[0093] Specifically, the diameters of the main body 1023 and the lever 103 are similar. When the lever 103 moves between the contact position and the separation position, the lever 103 is always located outside the main body 1023. When the lever 103 is in the contact position, it is in contact with the main body 1023; when the lever 103 is in the separation position, it is separated from the main body 1023. This effectively separates the lever 103 from the main body 1023, thereby reducing the contact friction between the lever 103 and the main body 1023 to a certain extent, reducing the resistance to movement, and improving the smoothness and reliability of the lever 103's movement.

[0094] When the paddle 103 moves between the contact position and the separation position, the inner diameter of the water separation cavity 115, the main body 1023, and the diameter of the paddle 103 are equivalent, thereby limiting the wobbling of the paddle 103 during movement and limiting the position of the main body 1023, improving the smoothness and reliability of the movement of the paddle 103 and the reliability of the main body 1023.

[0095] Optionally, the contact surface between the inner wall of the water distribution cavity 115 and the paddle 103 is smooth, which can improve the smoothness and reliability of the movement of the paddle 103 to a certain extent.

[0096] Optionally, a sealing element is provided between the inner wall of the water distribution cavity 115 and the main body 1023 to seal the gap between the main body 1023 and the water distribution cavity 115.

[0097] In some implementations, please refer to Figures 2 to 4 The guide structure 104 includes a first part 1041 and a second part 1042. The first part 1041 is disposed on the upper cover 102, and the second part 1042 is disposed on the paddle 103. One of the first part 1041 and the second part 1042 is provided with a guide channel 1043, and the other part includes a guide block 1044, which is disposed in the guide channel 1043.

[0098] The guide channel 1043 and the guide block 1044 cooperate with each other to guide the paddle 103 as it moves between the engagement position and the disengagement position.

[0099] In the above embodiments, the guide channel 1043 and the guide block 1044 can ensure to a certain extent that the paddle 103 can move to the correct fitting position, thereby realizing the connection or non-connection of the first through hole 1021 and the second through hole 1031.

[0100] Specifically, in one embodiment, the upper cover 102 is provided with a guide channel 1043, and the paddle 103 includes a guide block 1044. In another embodiment, the paddle 103 is provided with a guide channel 1043, and the upper cover 102 includes a guide block 1044.

[0101] The paddle 103 is movable relative to the upper cover 102. The paddle 103 can be rotated to a corresponding position by the cooperation of the guide channel 1043 and the guide block 1044. In one embodiment, when the paddle 103 is guided to the fitting position by the guide structure 104, one first through hole 1021 and the second through hole 1031 are connected, while the other first through hole 1021 and the second through hole 1031 are not connected.

[0102] In some implementations, please refer to Figure 3 , Figure 5 and Figure 6 The guide channel 1043 includes an upper guide channel 1045 and a lower guide channel 1046. The upper guide channel 1045 includes an upper inclined sidewall 1048, and the openings of the upper inclined sidewall 1048 and the lower guide channel 1046 are opposite each other in the vertical direction.

[0103] When the paddle 103 is in the separated position, the guide block 1044 is located in the lower guide channel 1046; when the paddle 103 is in the engaged position, the guide block 1044 is located in the upper guide channel 1045.

[0104] During the process of the paddle 103 moving from the separation position to the engagement position, after the guide block 1044 leaves the lower guide channel 1046, the upper inclined sidewall 1048 and the guide block 1044 cooperate to make the guide block 1044 enter the corresponding upper guide channel 1045 in the vertical direction.

[0105] In the above embodiments, the upper inclined sidewall 1048 and the guide block 1044 can cooperate with each other to achieve the rotation of the paddle 103 by the force of water flow impact.

[0106] Specifically, during the process of the paddle 103 moving from the separation position to the engagement position, that is, during the process of the guide block 1044 moving from a lower guide channel 1046 to an upper guide channel 1045, the guide block 1044 will only enter the upper guide channel 1045 corresponding to the lower guide channel 1046.

[0107] It should be noted that the paddle 103 moves relative to the upper cover 102. In one embodiment, the paddle 103 is provided with a guide channel 1043. During the process of the paddle 103 moving from the separated position to the engaged position, the guide channel 1043 can move relative to the guide block 1044. During the movement of the guide channel 1043, the guide block 1044 enters the upper guide channel 1045 from the lower guide channel 1046 through the guide of the upper inclined side wall 1048.

[0108] In one embodiment, the paddle 103 includes a guide block 1044. During the process of the paddle 103 moving from the separation position to the engagement position, the guide block 1044 can move relative to the guide channel 1043. During the movement of the guide block 1044, the guide block 1044 enters the upper guide channel 1045 from the lower guide channel 1046 through the guidance of the upper inclined sidewall 1048.

[0109] Understandably, under the impact of water flow, the paddle 103 will experience an upward vertical force, causing it to move upward. During this upward movement, after the guide block 1044 leaves the lower guide channel 1046, the upward-sloping sidewall 1048, opposite to the opening of the lower guide channel 1046, can guide the guide block 1044 into the corresponding upper guide channel 1045. The lower guide channel 1046 and the upper guide channel 1045 are arranged alternately in the vertical direction, allowing the paddle 103 to rotate during its movement.

[0110] In some implementations, please refer to Figure 3 , Figure 5 and Figure 6 The guide channel 1043 includes an upper guide channel 1045 and a lower guide channel 1046. The lower guide channel 1046 includes a lower inclined sidewall 1049, and the lower inclined sidewall 1049 and the opening of the upper guide channel 1045 are opposite each other in the vertical direction.

[0111] When the paddle 103 is in the separated position, the guide block 1044 is located in the lower guide channel 1046; when the paddle 103 is in the engaged position, the guide block 1044 is located in the upper guide channel 1045.

[0112] During the process of the paddle 103 moving from the contact position to the separation position, after the guide block 1044 leaves the upper guide channel 1045, the lower inclined side wall 1049 and the guide block 1044 cooperate with each other to make the guide block 1044 enter the corresponding lower guide channel 1046 in the vertical direction from the upper guide channel 1045.

[0113] In the above embodiments, the lower inclined sidewall 1049 and the guide block 1044 can cooperate with each other to achieve the rotation of the paddle 103 by gravity.

[0114] Specifically, during the process of the paddle 103 moving from the contact position to the separation position, that is, during the process of the guide block 1044 moving from an upper guide channel 1045 to a lower guide channel 1046, the guide block 1044 will only enter the lower guide channel 1046 corresponding to the upper guide channel 1045.

[0115] It should be noted that the paddle 103 moves relative to the upper cover 102. In one embodiment, the paddle 103 is provided with a guide channel 1043. During the process of the paddle 103 moving from the contact position to the separation position, the guide channel 1043 can move relative to the guide block 1044. During the movement of the guide channel 1043, the guide block 1044 enters the lower guide channel 1046 from the upper guide channel 1045 through the guide of the lower inclined side wall 1049.

[0116] In one embodiment, the paddle 103 includes a guide block 1044. During the process of the paddle 103 moving from the contact position to the separation position, the guide block 1044 can move relative to the guide channel 1043. During the movement of the guide block 1044, the guide block 1044 enters the lower guide channel 1046 from the upper guide channel 1045 through the guide of the lower inclined sidewall 1049.

[0117] Understandably, in the absence of water flow impact, the paddle 103 will be subjected to its own weight, moving downwards. During this downward movement, after the guide block 1044 leaves the upper guide channel 1045, the downward-sloping sidewall 1049, opposite the opening of the upper guide channel 1045, can guide the guide block 1044 into the corresponding lower guide channel 1046. The upper guide channel 1045 and the lower guide channel 1046 are staggered in the vertical direction, allowing the paddle 103 to rotate during its movement.

[0118] In some implementations, please refer to Figure 3 The guide channel 1043 is formed by two adjacent guide portions 1047 spaced apart in the circumferential direction of the upper cover 102 or the lever 103.

[0119] The above implementation method has a simple structure and can improve production and processing efficiency to a certain extent.

[0120] Specifically, the guide structure 104 may include a plurality of guide portions 1047, which are spaced apart on the circumferential sidewall of the upper cover 102 or the lever 103, and a guide channel 1043 is formed between two adjacent guide portions 1047.

[0121] In one embodiment, the guide portion 1047 may include an upper guide portion and a lower guide portion, with an upper guide channel 1045 formed between two adjacent upper guide portions and a lower guide channel 1046 formed between two adjacent lower guide portions.

[0122] In one implementation, please refer to Figure 3 The guide section 1047 has a trapezoidal protrusion structure, and the inclined side of one trapezoidal protrusion forms an upper inclined sidewall 1048 or a lower inclined sidewall 1049; the upper base and inclined side of one trapezoidal protrusion together with the lower base of another adjacent trapezoidal protrusion form a guide channel 1043.

[0123] Optionally, the first part 1041 or the second part 1042 of the guide channel 1043 is further provided with a transition channel, which may be located between the upper guide channel 1045 and the lower guide channel 1046.

[0124] Optionally, in one embodiment, the guide block 1044 includes a first inclined wall 10441 and a second inclined wall 10442. The first inclined wall 10441 is parallel to the upper inclined side wall 1048, and the second inclined wall 10442 is parallel to the lower inclined side wall 1049. The first inclined wall 10441 is closer to the upper cover 102 than the second inclined wall 10442. During the movement of the paddle 103 from the separated position to the engaged position, after the guide block 1044 leaves the lower guide channel 1046, the first inclined wall 10441 contacts the upper inclined side wall 1048 to allow the guide block 1044 to enter the corresponding upper guide channel 1045. During the movement of the paddle 103 from the engaged position to the separated position, after the guide block 1044 leaves the upper guide channel 1045, the second inclined wall 10442 contacts the lower inclined side wall 1049 to allow the guide block 1044 to enter the corresponding lower guide channel 1046. In one embodiment, the guide block 1044 has a triangular protruding structure.

[0125] In some implementations, please refer to Figure 2 and Figure 2A One of the top cover 102 and the lever 103 is provided with an insertion part 105, and the other is provided with an insertion hole 106.

One of the guide channel 1043 and the guide block 1044 is provided on the circumferential side of the insertion part 105, and the other is provided on the circumferential wall of the insertion hole 106.

[0126] In the above embodiments, the swivel, eccentricity or jamming of the paddle 103 during rotation can be prevented to a certain extent, thereby improving the stability and reliability of the movement of the paddle 103.

[0127] Specifically, the insertion part 105 can be a columnar structure, and the insertion hole 106 is a sleeve structure that matches it. After the insertion part 105 is inserted into the insertion hole 106, relative movement can occur between the insertion part 105 and the insertion hole 106, so that the upper cover 102 and the lever 103 can be movably connected.

[0136] The guide channel 1043 includes an upper guide channel 1045 and a lower guide channel 1046. The upper guide channel 1045 and the lower guide channel 1046 are distributed vertically, so that the paddle 103 can move up and down to move between the separation position and the engagement position.

[0137] In some implementations, please refer to Figure 3 The water distribution chamber 115 is provided with a mounting part 1151, and the lever 103 includes a hollow column 1033. The hollow column 1033 is provided with an insertion hole 106, and the bottom end of the hollow column 1033 is movably connected to the mounting part 1151.

[0138] The reliability of the movement of the paddle 103 can be improved in the above embodiments.

[0139] Specifically, the mounting part 1151 may be provided with a mounting cavity, the diameter of which is slightly larger than the outer diameter of the hollow column 1033, and the bottom end of the hollow column 1033 may be inserted into the mounting cavity. When the lever 103 moves, the bottom end of the hollow column 1033 may move up and down within the mounting cavity.

[0144] In the above embodiments, the first through hole 1021 can be opened and closed independently, thereby allowing selection of different spray arms as needed, thus improving water conservation and work efficiency.

[0145] Specifically, one first through hole 1021 can communicate with the upper spray arm 200 and / or the top spray arm 400, and the other first through hole 1021 can communicate with the lower spray arm 300. When the lever 103 moves to the contact position, the second through hole 1031 communicates with one of the two first through holes 1021, but not with the other.
