The lid has a receiving cavity, a spray nozzle, and a clearance channel located in the rotating part. The spray nozzle sprays water into the body. A flexible hose is installed in the receiving cavity. One end of the hose is connected to the spray nozzle, and the other end extends downward through the clearance channel out of the receiving cavity. A first clearance channel extending in a first direction and a second clearance channel extending in a second direction form an angle. When the lid is closed, at least a portion of the first clearance channel forms a horizontally extending clearance section, allowing the hose to pass through the clearance section of the first clearance channel out of the receiving cavity.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to a countertop water purifier. Background Technology

[0002] Countertop water purifiers, as smart home appliances integrating filtration and heating functions, are advantageous due to their small size, allowing them to be placed directly on a countertop. They have gradually evolved into upgraded products with an attached tea brewing compartment. The tea brewing compartment, located at the front upper part of the machine, includes the compartment body and a lid. The lid is flipped open and closed to add tea leaves and seal the container. The lid has a water spray mechanism that sprays water into the compartment. After placing tea leaves or other suitable brewing ingredients into the compartment, the heating element inside the machine, controlled by a program, delivers hot water through a steam separator to the water spray mechanism, which then sprays the water into the compartment, thus brewing the tea.

[0003] In existing technology, tea brewing chambers use a flexible hose to supply water to a spray mechanism. One end of the hose is connected to the hot water outlet of the water vapor separator, and the other end is connected to the spray mechanism. To avoid the hose interfering with the opening and closing of the chamber lid, the hose typically enters the lid through the rotating part of the lid. Therefore, as the lid rotates, the hose twists synchronously, making it susceptible to compression from the lid, resulting in tangling or bending. In severe cases, the hose may be flattened, affecting water flow and potentially breaking, leading to leakage. Some tea brewing chambers use rigid water pipes instead of flexible hoses, which improves the problems of flattening and tangling, but limits the opening angle of the lid.

[0004] Furthermore, although the water-vapor separator can separate steam, its exhaust relies mainly on external pipes or independent exhaust ports located on the side wall of the machine, affecting the aesthetics of the equipment. Moreover, the lid and body use a traditional hinge structure for rotational connection, making it impossible to keep the lid suspended; after opening, manual support is required, impacting user convenience. Utility Model Content

[0005] To address the aforementioned technical issues, this application provides a countertop water purifier whose tea brewing chamber achieves extended hose life, steam emission, and arbitrary angle suspension by optimizing the layout of the avoidance channel, integrating exhaust function, and damping suspension structure.

[0006] The technical solution adopted in this application is as follows:

[0007] A countertop water purifier includes a body and a tea brewing chamber mounted on the body. The tea brewing chamber includes a chamber body and a lid. The lid has a rotating part pivotally connected to the chamber body, allowing the chamber body to be opened or closed by rotating about an axis. The lid has a receiving cavity, a water spraying part, and a clearance channel provided in the rotating part. The water spraying part is used to spray water into the chamber body. A flexible hose for guiding water flow to the water spraying part is installed in the receiving cavity. One end of the flexible hose is connected to the water spraying part in the receiving cavity, and the other end extends out of the receiving cavity from the clearance channel and downwards. The clearance channel includes a first clearance channel extending along a first direction and a second clearance channel extending along a second direction, the first direction and the second direction forming an angle; when the cover is closed, at least a portion of the first clearance channel forms a horizontally extending clearance section, allowing the hose to pass through the clearance section of the first clearance channel out of the receiving cavity; when the cover is open, at least a portion of the second clearance channel forms a horizontally extending clearance section, allowing the hose to be horizontally offset from the first clearance channel into the clearance section of the second clearance channel.

[0008] In this technical solution, the first clearance channel extends along a first direction, and the second clearance channel extends along a second direction. By making the first and second directions form an angle, the clearance channels switch opening directions during the rotation of the lid as it opens and closes, forcing the hose to adjust its path. Specifically, when the lid is closed, at least a portion of the first clearance channel forms a horizontally extending clearance section. The hose passes through this clearance section, exits the receiving cavity, and extends downwards. The horizontally extended space of this clearance section provides relatively sufficient receiving space for the hose, preventing it from being squeezed. When the lid rotates open from the closed state... The first clearance channel rotates to a state that is biased towards verticality and is not suitable for accommodating the hose. At this time, at least part of the second clearance channel forms a horizontally extending clearance section. Driven by the cover, the hose passes through the clearance section of the second clearance channel, exits the receiving cavity, and extends downward. The horizontal extension of the clearance section also provides relatively sufficient space for the hose, avoiding excessive twisting or bending of the hose due to the rotation of the cover. This solves the problem of squeezing caused by the sudden change in the path of the hose when the cover is opened and closed, extends the life of the hose, ensures that the deformation of the hose is controllable during the opening and closing of the cover, avoids breakage or obstruction of water flow, and simplifies the structural layout.

[0009] Each end of the rotating part is provided with a pivot hole, and the pivot holes at both ends are arranged at intervals. The clearance channel is formed in the interval area between the two pivot holes. The compartment is provided with a rotating shaft corresponding to the two pivot holes, and the rotating shaft is inserted into the pivot hole from the end of the rotating part.

[0010] In this technical solution, the clearance channel is arranged in the interval area between the two pivot holes, and the end of the rotating part of the rotating shaft is inserted into the pivot hole. This avoids spatial interference between the mating structure formed by the rotating shaft and the pivot hole and the hose in the clearance channel. This ensures the stability of the cover rotation, the reliability of the hose switching position between the first clearance channel and the second clearance channel as the cover rotates, and makes full use of the internal space of the rotating part to achieve a compact design.

[0011] The hopper includes a main body and a cover plate attached to the top of the main body. The cover plate is provided with a first mating component and a second mating component that are detachable. The first mating component and the second mating component are respectively located on both sides of the rotating part. The first mating component is provided with a first rotating shaft, and the second mating component is provided with a second rotating shaft. The first rotating shaft and the second rotating shaft are respectively pivoted in two pivot holes and are arranged coaxially.

[0012] In this technical solution, by making the first and second mating parts detachable on the cover plate, it is easy to align and install the first and second rotating shafts with the pivot holes at both ends of the rotating part, avoiding structural interference during installation. During installation, the hose can be pre-passed through the rotating part and the first and second mating parts can be mated with the rotating part before being installed as a whole on the cover plate, simplifying the assembly process and reducing assembly difficulty. The separate design of the main body and the cover plate, as well as the detachable design of the first and second mating parts on the cover plate, make the cover modular, which is convenient for maintenance and replacement, and also reduces the processing difficulty.

[0013] The cavity is provided with a protruding baffle. When the cover is opened, the baffle guides the hose into the avoidance section of the second avoidance channel.

[0014] In this technical solution, the baffle restricts the hose's offset path when the cover is opened, forcibly guiding the hose into the avoidance section of the second avoidance channel. This prevents the hose from excessively deviating from the predetermined rotation trajectory of the avoidance channel when the cover is opened, ensuring that the hose is always under control, avoiding entanglement or wear with other components in the containment cavity, and reducing the risk of the cover not closing properly due to hose jamming.

[0015] The angle formed by the first direction and the second direction is set as α, where α is greater than or equal to 70° and less than or equal to 110°.

[0016] In this technical solution, the angle between the first direction and the second direction is controlled between 70° and 110°, so that the turning angle of the avoidance channel conforms to ergonomics. This not only adapts to the opening and closing angle range of the cover from the closed position to the fully open position, but also avoids the increase in water flow resistance or accelerated aging of the hose due to the excessively small bending radius of the hose.

[0017] The machine body is equipped with a heating element and a water vapor separation box. The water vapor separation box is equipped with a water vapor separation chamber and a hot water inlet, a hot water outlet and an air outlet respectively connected to the water vapor separation chamber. The hot water inlet is connected to the hot water outlet of the heating element, and the hot water outlet is connected to the hose. The cover is equipped with an exhaust port that is connected to the outside atmosphere, and the air outlet is connected to the exhaust port.

[0018] In this technical solution, steam is separated from hot water through a water-vapor separator and discharged through an exhaust port. This prevents high-temperature steam from directly entering the tea brewing chamber and affecting the brewing effect, while also preventing steam from condensing inside the machine and causing moisture damage to circuit components, thus improving equipment safety. Furthermore, integrating the exhaust port into the chamber cover reduces reliance on external pipes and separate exhaust ports located on the side wall of the machine, enhancing the aesthetics of the device.

[0019] Each of the two ends of the rotating part is provided with a pivot hole, and the pivot holes at both ends are arranged at intervals. The chamber body is provided with a rotating shaft corresponding to the two pivot holes. The rotating shaft is provided with a shaft hole that passes through the two shaft ends. The exhaust port is provided on one of the rotating parts. The exhaust port passes through the pivot hole and corresponds to the shaft hole. The air outlet is connected to the exhaust port through the shaft hole.

[0020] In this technical solution, by connecting the outlet of the water vapor separator to the shaft hole inside the rotating shaft, the steam is discharged from the exhaust port of the rotating part along the axial direction of the rotating shaft, so that the exhaust path and the rotation axis of the cover are physically coincided, eliminating the structural redundancy caused by external pipes, reducing assembly costs and the risk of water leakage.

[0021] The rotating part is provided with a pivot hole, and the compartment body is provided with a rotating shaft that pivots with the pivot hole. A damping structure is provided between the rotating shaft and the inner wall of the pivot hole. The damping structure contacts the circumferential surface of the rotating shaft or the inner wall of the pivot hole and generates friction, so that the compartment cover is suspended at any opening angle by the friction during the opening process.

[0022] In this technical solution, the damping structure allows the lid to be suspended at any position between the closed and fully open positions. Users can freely adjust the opening angle to adapt to different operational needs (such as adding tea or cleaning), solving the problem that traditional lids need to be manually supported at the required angle, thus improving operational convenience.

[0023] The damping structure consists of multiple O-rings fitted onto the rotating shaft, with the outer circumferential surface of the O-rings interfering with the inner wall of the pivot hole; when the cover rotates around the rotating shaft, the O-rings are squeezed by the inner wall of the pivot hole to form frictional damping.

[0024] In this technical solution, multiple O-rings are used as damping structures. The elastic deformation of the interference fit provides uniform frictional resistance. The structure is simple and low in cost, and it is also easy to assemble. At the same time, the redundant design of the O-rings avoids damping failure caused by single-point failure.

[0025] The cover includes an outer cover and an inner liner. The outer cover and the inner liner are detachably fitted to form the receiving cavity. The water spraying part and the rotating part are disposed on the inner liner. The outer cover and the inner liner cooperate to form a clamping part. The clamping part applies a clamping force to the hose to form a limiting force.

[0026] In this technical solution, the clamping part of the outer cover and the inner liner applies a limiting clamping force to the hose to prevent the hose from shaking and being unable to switch stably between the first and second clearance channels. At the same time, the detachable fit of the outer cover and the inner liner facilitates hose maintenance. Attached Figure Description

[0052] In the embodiments of this application, reference is made to Figures 1 to 11 As shown, a countertop water purifier is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0053] Example 1:

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the tabletop water purifier provided in this application includes a body 1 and a tea brewing chamber installed on the body 1. The tea brewing chamber includes a chamber body 2 and a chamber cover 3. The chamber cover 3 has a rotating part 31 pivotally connected to the chamber body 2, so as to open or close the chamber body 2 by rotating around an axis. The chamber cover 3 has a receiving cavity 32, a water spraying part 33, and a clearance channel 34 provided in the rotating part 31. The water spraying part 33 is used to spray water into the chamber body 2. A flexible hose 4 for guiding water flow to the water spraying part 33 is installed in the receiving cavity 32. One end of the flexible hose 4 is connected to the water spraying part 33 in the receiving cavity 32, and the other end extends downward from the receiving cavity 32 through the clearance channel 34. The clearance channel 34 includes a first clearance channel 341 extending in a first direction and a second clearance channel 342 extending in a second direction, with the first direction and the second direction forming an angle. Figure 7 and Figure 9 The diagram shows the state when the cover 3 is closed. When the cover 3 is closed, at least a portion of the first clearance channel 341 forms a horizontally extending clearance section, allowing the hose 4 to pass through the clearance section of the first clearance channel 341 and exit the receiving cavity 32; as shown Figure 5 The diagram shows the state when the cover 3 is fully open. When the cover 3 is open, at least a portion of the second clearance channel 342 forms a horizontally extending clearance section, allowing the hose 4 to be horizontally shifted from the first clearance channel 341 into the clearance section of the second clearance channel 342.

[0055] Those skilled in the art will understand that if the clearance channel is set as a traditional single-direction opening, for example, when the cover is closed, the clearance channel opening faces downwards, and when the cover is opened, the clearance channel becomes vertical. Since the hose needs to extend downwards after passing through the clearance channel, the clearance channel lacks horizontal clearance space for the hose, causing the inner wall of the clearance channel to force the hose to undergo a severe Z-shaped change, resulting in the hose being laterally squeezed and flattened. However, in this technical solution, the clearance channel 34 includes a first clearance channel 341 and a second clearance channel 342. The first clearance channel 341 extends along a first direction, and the second clearance channel 342 extends along a second direction. By making the first direction and the second direction form an angle, the first clearance channel 341 and the second clearance channel 342 switch opening directions during the rotation of the clearance channel 3 as it opens and closes, forcing the hose 4 to adjust its path. Specifically, as shown in the figure... Figure 7 As shown, when the cover 3 is closed, at least a portion of the first clearance channel 341 forms a horizontally extending clearance section. The hose 4 passes through this clearance section, exits the receiving cavity 32, and extends downward. The horizontally extended space of this clearance section provides relatively sufficient receiving space for the hose 4, preventing compression of the hose 4; Figure 6As shown, when the cover 3 rotates open from the closed state, the clearance section of the first clearance channel 341 rotates to a state that is biased towards verticality and is not suitable for accommodating the hose 4. After the hose 4 detaches from the first clearance channel 341, the inner wall of the first clearance channel 341 no longer forces the hose 4 to undergo a severe Z-shaped abrupt change. Although the hose 4 will also undergo structural changes at this time, the changes are small and gradual. At this time, at least part of the second clearance channel 342 forms a horizontally extending clearance section. Driven by the cover 3, the hose 4 passes through the clearance section of the second clearance channel 342, exits the receiving cavity 32, and extends downward. The horizontal extension space of the clearance section of the second clearance channel 342 also provides relatively sufficient accommodating space for the hose 4, avoiding excessive twisting or bending of the hose 4 due to the rotation of the cover 3, solving the squeezing problem caused by the path change of the hose 4 when the cover 3 is opened and closed, extending the service life of the hose 4, ensuring that the deformation of the hose 4 is controllable during the opening and closing of the cover 3, avoiding damage or obstruction of water flow, and simplifying the structural layout. This application does not limit the structure of the spray section 33; for example, it can adopt a shower head structure. This application also does not limit the material of the hose 4; it is preferably a silicone hose.

[0056] As a preferred example in this embodiment, such as Figure 4 and Figure 9 As shown, each end of the rotating part 31 has a pivot hole 35, which are spaced apart. A clearance channel 34 is formed in the space between the two pivot holes 35. The compartment 2 has a rotating shaft corresponding to the two pivot holes 35, which is inserted into the pivot hole 35 from the end of the rotating part 31. In this technical solution, the clearance channel 34 is arranged in the space between the two pivot holes 35, which avoids spatial interference between the pivot hole 35 and the hose 4. The rotating shaft is inserted into the pivot hole 35 from the end of the rotating part 31, which also avoids spatial interference between the rotating shaft and the hose 4. Therefore, the mating structure formed by the rotating shaft and the pivot hole 35 is prevented from causing spatial interference between the hose 4 in the clearance channel 34. This ensures the stability of the rotation of the compartment cover 3 and the reliability of the hose 4 switching positions between the first clearance channel 341 and the second clearance channel 342 as the compartment cover 3 rotates. It also makes full use of the internal space of the rotating part 31 and achieves a compact design.

[0057] Furthermore, such as Figure 3 , Figure 8 and Figure 9 As shown, the hopper 2 includes a main body 21 and a cover plate 22 that covers the top of the main body 21. The cover plate 22 has a first mating part 23 and a second mating part 24 that are respectively detachable. The first mating part 23 and the second mating part 24 are located on both sides of the rotating part 31. The first mating part 23 has a first rotating shaft 231, and the second mating part 24 has a second rotating shaft 241. The first rotating shaft 231 and the second rotating shaft 241 are respectively pivoted in two pivot holes 35 and are arranged coaxially. Figure 8The image shows the state of cover plate 22 after the first mating part 23 and the second mating part 24 have been removed from cover plate 22. Figure 3 The diagram shows the first mating component 23 and the second mating component 24 installed on the cover plate 22. In this technical solution, the detachable design of the first mating component 23 and the second mating component 24 on the cover plate 22 facilitates the alignment and installation of the first rotating shaft 231 and the second rotating shaft 241 with the pivot holes 35 at both ends of the rotating part 31, avoiding structural interference during installation. During installation, the hose 4 can be pre-passed through the clearance channel 34, and the first mating component 23 and the second mating component 24 can be mated with the rotating part 31 before being installed as a whole on the cover plate 22, simplifying the assembly process and reducing assembly difficulty. The separate design of the main body 21 and the cover plate 22, as well as the detachable design of the first mating component 23 and the second mating component 24 on the cover plate 22, modularizes the compartment cover 3, facilitating maintenance and replacement, and reducing processing difficulty. Specifically, the first mating component 23 and the second mating component 24 can be detached using screws or clips.

[0058] Example 2:

[0059] The structure and principle of this embodiment 2 are basically the same as those of embodiment 1, except that: Figure 6 As shown, the receiving cavity 32 is provided with a protruding baffle 36. When the cover 3 is opened, the baffle 36 guides the hose 4 into the clearance section of the second clearance channel 342. Those skilled in the art will understand that, due to the flexible nature of the hose 4, if it is not properly restrained, the hose 4 is prone to deviation during the rotation of the cover 3. Therefore, in this technical solution, the baffle 36 restricts the deviation path of the hose 4 when the cover 3 is opened. For example, in… Figure 6 In the open state of the cover 3 shown, the baffle 36 forces the bent portion of the hose 4 downwards, preventing it from bouncing upwards. This forcibly guides the hose 4 into the clearance section of the second clearance channel 342, preventing excessive displacement of the hose 4 from deviating from the predetermined rotation trajectory of the clearance channel 34 when the cover 3 is open. This ensures the hose 4 remains under control, preventing it from tangling or abrading with other components within the receiving cavity 32, and reducing the risk of the cover 3 not closing properly due to hose 4 jamming. Specifically, this application does not limit the structure of the baffle 36; for example, it can be... Figure 6 As shown in the annular structure, when the cover 3 is opened, the space enclosed by the baffle 36 guides the flexible hose 4 to move backward into the clearance section of the second clearance channel 342. The baffle 36 can also be configured with other suitable structures, such as a point-discontinuity structure, a crescent-shaped structure, etc.

[0060] Example 3:

[0061] The structure and principle of Embodiment 3 are basically the same as those of Embodiments 1 and 2, except that the angle between the first and second directions is set as α, which is greater than or equal to 70° and less than or equal to 110°. In this technical solution, the angle between the first and second directions is controlled between 70° and 110°, so that the turning angle of the avoidance channel 34 conforms to ergonomics. This allows it to adapt to the opening and closing angle range of the cover 3 from the closed position to the fully open position, while also avoiding excessively small bending radius of the hose 4, which could increase water flow resistance or accelerate hose 4 aging. Figure 6 In the example shown, the dashed line L1 represents the first direction and the dashed line L2 represents the second direction. The angle α between L1 and L2 is close to 90°. Based on this, it is preferable to set the opening angle of the cover 3 between the closed position and the fully open position to 90°. Therefore, when the cover 3 is closed, the first clearance channel 341 is almost horizontal, thus providing as much horizontal clearance space as possible for the hose 4, and the second clearance channel 342 is almost vertical. When the cover 3 is rotated 90° to the fully open position, the first clearance channel 341 is almost vertical, and the second clearance channel 342 is almost horizontal, thus providing as much horizontal clearance space as possible for the hose 4.

[0062] Example 4:

[0063] The structure and principle of this embodiment 4 are basically the same as those of embodiments 1-3, except that: Figures 9 to 11 As shown, the main body 1 contains a heating element 5 and a water vapor separation box 6. The water vapor separation box 6 has a water vapor separation chamber and a hot water inlet, a hot water outlet, and a vent that are respectively connected to the water vapor separation chamber. The hot water inlet is connected to the hot water outlet of the heating element 5, and the hot water outlet is connected to a flexible hose 4. The cover 3 has an exhaust port 37 that is connected to the outside atmosphere, and the vent is connected to the exhaust port 37. Specifically, the heating element 5 is used to heat the filtered room temperature water to the required temperature. When the tea brewing function is started, the heating element 5 delivers hot water to the spray section 33 through the water vapor separation box 6 and the flexible hose 4. After the hot water enters the water vapor separation box 6, water vapor separation is achieved. The hot water enters the flexible hose 4, and the steam reaches the exhaust port 37 through the flexible hose 4 and is discharged. This avoids high-temperature steam directly entering the tea brewing chamber and affecting the brewing effect, and at the same time prevents steam from condensing inside the main body 1 and causing the circuit components to become damp, thus improving the safety of the equipment. In addition, integrating the exhaust port 37 into the cover 3 reduces the reliance on external pipes and independent exhaust ports opened on the side wall of the main body 1, improving the aesthetics of the equipment.

[0064] Furthermore, a pivot hole 35 is provided at each end of the rotating part 31, and the pivot holes 35 at both ends are arranged at intervals. The chamber 2 is provided with a rotating shaft corresponding to the two pivot holes 35. The rotating shaft is provided with a shaft hole 232 passing through the two shaft ends. An exhaust port 37 is provided on one of the rotating parts 31. The exhaust port 37 passes through the pivot hole 35 and corresponds to the shaft hole 232. The exhaust port is connected to the exhaust port 37 through the shaft hole 232. Specifically, based on the structure of the aforementioned embodiment 1, the two rotating shafts are respectively a first rotating shaft 231 and a second rotating shaft 241. The shaft hole 232 passing through the two shaft ends can be provided on either the first rotating shaft 231 or the second rotating shaft 241. Figure 10 The diagram shows that the first rotating shaft 231 has shaft holes 232 penetrating both ends of the shaft. An exhaust port 37 is located on the end wall of the pivot hole 35 and corresponds to the shaft hole 232. Steam discharged from the water vapor separator 6 reaches the exhaust port 37 through the shaft hole 232. In this technical solution, by connecting the exhaust port of the water vapor separator 6 to the shaft hole 232 inside the rotating shaft, steam is discharged from the exhaust port 37 of the rotating part 31 along the axial direction of the rotating shaft. This achieves physical overlap between the exhaust path and the rotation axis of the cover 3, eliminating structural redundancy caused by external pipes and reducing assembly costs and leakage risks. Furthermore, for the scheme where the clearance channel 34 is formed in the interval area between the two pivot holes 35, the hose 4 is confined between the two pivot holes 35, allowing the steam discharged from the exhaust port 37 to flow towards the hose 4. This preheats the hose 4, reducing heat loss of hot water from the water vapor separator 6 through the hose 4 to the spray section 33.

[0065] Example 5:

[0066] The structure and principle of this embodiment 5 are basically the same as those of embodiments 1-4. The difference lies in that a damping structure is provided between the rotating shaft and the inner wall of the pivot hole 35. The damping structure contacts the circumferential surface of the rotating shaft or the inner wall of the pivot hole 35 and generates friction, allowing the lid 3 to be suspended at any opening angle during the opening process due to friction. Specifically, it can be based on the structure of the aforementioned embodiment 1, with the two rotating shafts being the first rotating shaft 231 and the second rotating shaft 241. The damping structure can be located between the first rotating shaft 231 and the pivot hole 35, or it can be located between the second rotating shaft 241 and the pivot hole 35. The damping structure allows the lid 3 to be suspended at any position between the closed position and the fully open position. Users can freely adjust the opening angle to adapt to different operational needs (such as adding tea leaves, washing, etc.), solving the problem that traditional lids need to be manually supported at the required angle, thus improving operational convenience.

[0067] Furthermore, the damping structure consists of multiple O-rings 7 fitted onto the rotating shaft, such as... Figure 10The diagram shows an example of an O-ring 7 fitted onto the first rotating shaft 231. The outer circumferential surface of the O-ring 7 is interference-fitted with the inner wall of the pivot hole 35. When the cover 3 rotates around the shaft, the O-ring 7 is compressed by the inner wall of the pivot hole 35, forming frictional damping. In this technical solution, multiple O-rings 7 are used as a damping structure. The elastic deformation of the interference fit provides uniform frictional resistance. The structure is simple and low-cost, and easy to assemble. At the same time, the redundant design of the O-rings 7 avoids damping failure due to single-point failure.

[0068] As a preferred embodiment of this application, all the foregoing embodiments can further include an outer cover 38 and an inner liner 39, with the outer cover 38 and the inner liner 39 detachably fitted to form a receiving cavity 32. A water spraying part 33 and a rotating part 31 are disposed on the inner liner 39. The outer cover 38 and the inner liner 39 cooperate to form a clamping part, which applies a clamping force to the hose 4 to form a limiting position. Specifically, as... Figure 6 As shown, at least one of the outer cover 38 and the inner liner 39 can be provided with a protrusion 391 protruding from the outside into the receiving cavity 32, forming a clamping part. In this solution, the clamping part of the outer cover 38 and the inner liner 39 applies a limiting clamping force to the hose 4, preventing the hose 4 from shaking and failing to switch stably between the first clearance channel 341 and the second clearance channel 342. At the same time, the detachable connection of the outer cover 38 and the inner liner 39 facilitates the maintenance of the hose 4. Preferably, the outer cover 38 and the inner liner 39 can be detachably connected by a snap-fit, improving the ease of assembly and disassembly.
