Description

Technical Field

[0001] This application relates to the field of liquid dispensing devices in kitchen and bathroom appliances, and more specifically, to a liquid dispensing device. Background Technology

[0002] Currently, water dispensing devices such as shower heads typically have multiple nozzles distributed in different areas of the faceplate. Each nozzle can only dispense a single spray of water, and users can switch between dispensing functions using a function switch. This design restricts the dispensing areas of different dispensing modes, resulting in insufficient spray coverage for some functions and negatively impacting the user experience. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a liquid dispensing device that is not limited by the liquid dispensing area of ​​different liquid dispensing functions, which is conducive to expanding the liquid dispensing range of different liquid dispensing functions and improving the user experience.

[0004] This application provides a liquid dispensing device, including: a liquid dispensing device body, the liquid dispensing device body having an installation cavity and a liquid inlet communicating with the installation cavity; and a liquid dispensing cover assembly, at least partially located within the installation cavity, and enclosing a liquid dispensing area communicating with the liquid inlet together with the liquid dispensing device body, the liquid dispensing cover assembly having a liquid dispensing cavity, the two end walls of the liquid dispensing cavity in the thickness direction having a first liquid passage and a second liquid passage communicating with the liquid dispensing cavity; the liquid dispensing cavity is located downstream of the liquid dispensing area of ​​the liquid inlet, and is configured to allow liquid to enter through one of the first liquid passage and the second liquid passage and to exit through the other of the first liquid passage and the second liquid passage; and the first liquid passage and the second liquid passage have different liquid dispensing forms, the liquid dispensing cover assembly being configured to be able to flip relative to the liquid dispensing device body to switch the liquid dispensing form of the liquid dispensing device.

[0005] The liquid dispensing device provided in this application embodiment has two different liquid dispensing functions, and the switching between the two functions can be achieved by flipping the liquid dispensing cover assembly. Furthermore, the two liquid dispensing functions share the same dispensing chamber, and are not limited by the dispensing area. Therefore, both the first and second liquid outlets can be designed as large-area dispensing nozzles, and their shape and distribution can be arbitrarily designed. This allows both liquid dispensing functions of the device to achieve large-area dispensing and a relatively full dispensing range, thereby improving the user experience.

[0037] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0038] In the embodiments of this application, the liquid dispensing device can be a water dispensing device (i.e., the liquid flowing out is water), or it can be other types of liquid dispensing devices (such as the liquid flowing out is detergent, disinfectant, etc.). The water dispensing device can be a faucet with an aerator function, or it can be a faucet aerator or other types of liquid dispensing devices. The following is a detailed description using a shower head (the liquid flowing out is water) as an example.

[0039] like Figures 1 to 23 As shown in the figure, this application provides a liquid dispensing device.

[0040] The liquid dispensing device includes: a liquid dispensing device body 1 and a liquid dispensing surface cover assembly 2.

[0041] The liquid dispensing device body 1 is provided with a mounting cavity 121 (e.g. Figure 3 (as shown) and the liquid inlet 122 communicating with the mounting cavity 121 (as shown) Figure 7 (As shown).

[0042] The liquid outlet cover assembly 2 is at least partially located within the mounting cavity 121, and together with the liquid outlet device body 1, it encloses a liquid outlet area 1212 that communicates with the liquid inlet 122 (e.g., Figure 7 (As shown). The liquid outlet cover assembly 2 is provided with a liquid outlet cavity, and the two end walls of the liquid outlet cavity in the thickness direction are respectively provided with a first liquid passage 21 and a second liquid passage 22 communicating with the liquid outlet cavity, as shown. Figures 1 to 3 As shown. The liquid outlet chamber is located downstream of the liquid outlet area 1212 and is configured to allow liquid to enter through one of the first liquid outlet 21 and the second liquid outlet 22, and to exit through the other of the first liquid outlet 21 and the second liquid outlet 22.

[0043] Furthermore, the first liquid outlet 21 and the second liquid outlet 22 have different liquid discharge forms, and the liquid outlet cover assembly 2 is configured to be able to flip and switch relative to the liquid outlet device body 1 to switch the liquid discharge form of the liquid outlet device.

[0044] Among them, the liquid outlet device is a water-discharging shower head, the liquid outlet device body 1 is the shower head body, and the liquid flowing out of the water-discharging shower head is water.

[0045] When the outlet chamber is connected to the inlet 122 via the first outlet port 21 to allow water to enter and exit via the second outlet port 22, the water flows through the inlet 122, the outlet area 1212, and the first outlet port 21 into the outlet chamber, and is discharged through the second outlet port 22. Figure 8 As shown, the liquid discharge form of the liquid discharge device is determined by the structural form of the second liquid outlet 22.

[0046] When the outlet chamber is connected to the inlet 122 via the second outlet port 22 to allow water to enter and exit via the first outlet port 21, the water flows through the inlet 122, the outlet area 1212, and the second outlet port 22 into the outlet chamber, and is discharged through the first outlet port 21. Figure 5 and Figure 6 As shown, the liquid discharge form of the liquid discharge device is determined by the structural form of the first liquid outlet 21.

[0047] Therefore, the liquid dispensing device provided in this application embodiment has two different liquid dispensing functions, and the switching between the two functions can be achieved by flipping the liquid dispensing cover assembly 2. Furthermore, since the two liquid dispensing functions share the same liquid dispensing chamber and are not limited by the liquid dispensing area, both the first liquid outlet 21 and the second liquid outlet 22 can be configured as large-area water nozzles, and their shape and distribution can be arbitrarily designed. This allows both liquid dispensing functions of the device to achieve large-area liquid dispensing and have a relatively full liquid dispensing range, thereby improving the user experience.

[0048] In some exemplary embodiments, such as Figure 6 As shown, the liquid outlet cover assembly 2 includes a first cover 24 and a second cover 25 that are connected to each other, forming a liquid outlet chamber. The first cover 24 has a first liquid outlet 21 and a second liquid outlet 22. The first cover 24 and the second cover 25 can be threaded together. The liquid outlet cover assembly 2 may also include a partition 26 located inside the liquid outlet chamber, and the partition 26 has a liquid distribution hole 261, such as... Figure 6 As shown. The number of dispensing holes 261 can be multiple, and these holes 261 can be evenly distributed to facilitate uniform liquid distribution within the outlet chamber, thereby promoting uniform liquid discharge from the first outlet 21 / second outlet 22. The first cover 24 and the second cover 25 can be separately manufactured and then assembled, allowing for the reasonable setting of the size, structure, and distribution of the first outlet 21 and the second outlet 22 as needed, and also facilitating the assembly of the partition 26.

[0049] In some exemplary embodiments, such as Figure 3 , Figure 6 , Figure 17 and Figure 18 As shown, the first liquid outlet 21 includes multiple first liquid outlet holes 211, and the second liquid outlet 22 includes multiple second liquid outlet holes 221. The flow area of ​​the first liquid outlet holes 211 is smaller than the flow area of ​​the second liquid outlet holes 221. The multiple first liquid outlet holes 211 can be evenly distributed on one end wall of the liquid outlet cover assembly 2. The multiple second liquid outlet holes 221 can be evenly distributed on the other end wall of the liquid outlet cover assembly 2.

[0050] Thus, the shower head has two water outlet functions: large-hole water outlet (water inlet at the first liquid passage hole 211, water outlet at the second liquid passage hole 221) and small-hole water outlet (water inlet at the second liquid passage hole 221, water outlet at the first liquid passage hole 211). The large-hole water outlet function (such as...) Figure 8 As shown), dirt flows out easily and is not easily clogged; while the small-hole water outlet function (such as...) Figure 5 and Figure 6As shown, dirt is not easily discharged and is prone to clogging. Therefore, when the small hole is blocked, the liquid outlet cover assembly 2 can be flipped and switched to the large hole liquid outlet function. The water will then flow from the small hole to the large hole, and the water inlet and outlet functions at both ends of the small hole can be switched to achieve the backwashing function. The blocked material flushed out can also easily flow out from the large hole, thereby achieving the effect of backwashing and descaling, solving the pain points of users during use.

[0051] Of course, the first liquid outlet 21 and the second liquid outlet 22 can also adopt other structural forms, such as having the same water flow area but different distribution patterns to form different liquid outlet patterns.

[0052] In some exemplary embodiments, the liquid outlet cover assembly 2 is detachably coupled to the liquid outlet device body 1.

[0053] In this way, by disassembling the liquid outlet cover assembly 2, flipping it over on the outside of the liquid outlet device body 1, and then reinstalling it, the flipping and switching function of the liquid outlet cover assembly 2 can be realized. This is beneficial for reducing the thickness of the liquid outlet device body 1, achieving a thinning effect; it also helps to simplify the structure of the liquid outlet device, reduce production costs; and it also facilitates thorough cleaning after disassembly.

[0054] Furthermore, the liquid outlet cover assembly 2 is detachable, which facilitates modular customization. Multiple liquid outlet cover assemblies 2 with different liquid outlet forms can also be equipped. By replacing the liquid outlet cover assembly 2, a new liquid outlet device can be formed, realizing more liquid outlet functions. Moreover, each liquid outlet function can be designed to have a full liquid outlet range.

[0055] For example, the liquid outlet cover assembly 2 can be threaded or snapped to the liquid outlet device body 1, making it convenient for users to disassemble and assemble the liquid outlet cover assembly 2.

[0056] Of course, the liquid outlet cover assembly 2 and the liquid outlet device body 1 may not be detachable. For example, they may be rotatably connected, so that the liquid outlet cover assembly 2 can be rotated to achieve flipping and switching without disassembling it; or the liquid outlet cover assembly 2 can be pulled out and flipped before being put back without disassembling it.

[0057] In some exemplary embodiments, the liquid dispensing device further includes a locking mechanism that cooperates with the liquid dispensing cover assembly 2 and is configured to switch between a locked state of locking the liquid dispensing cover assembly 2 and an unlocked state of unlocking the liquid dispensing cover assembly 2, so that the liquid dispensing cover assembly 2 can be flipped relative to the liquid dispensing device body 1.

[0058] When the locking mechanism switches to the locked state, the liquid outlet cover assembly 2 is locked and relatively fixed to the liquid outlet device body 1. When the locking mechanism switches to the unlocked state, the liquid outlet cover assembly 2 is unlocked and can move freely relative to the liquid outlet device body 1, allowing for disassembly. The locking mechanism helps improve the stability of the liquid outlet cover assembly 2 during use.

[0059] In some exemplary embodiments, the liquid outlet cover assembly 2 is provided with a locking engagement portion. The locking mechanism includes: a locking element 31 (e.g., Figure 3 (as shown) and the first drive mechanism. The locking member 31 is movably connected to the liquid dispensing device body 1 and is configured to be in a locking position relative to the liquid dispensing device body 1 that engages with the locking mating part (as shown). Figure 10 (as shown) and the unlocked position of the disengaged locking part (as shown) Figure 12 The first drive mechanism is connected to the locking member 31 and is configured to drive the locking member 31 to move between the locked position and the unlocked position.

[0060] When the first driving member drives the locking member 31 to the locking position, the locking mechanism switches to the locking state. At this time, the locking member 31 cooperates with the locking part of the liquid outlet cover assembly 2, and the liquid outlet cover assembly 2 is locked to the liquid outlet device body 1, so the liquid outlet device can be used normally.

[0061] When the first driving member drives the locking member 31 to the unlock position, the locking mechanism switches to the unlock state. At this time, the locking member 31 separates from the locking engagement part of the liquid outlet cover assembly 2, the lock between the liquid outlet cover assembly 2 and the liquid outlet device body 1 is unlocked, and the liquid outlet cover assembly 2 can be removed from the liquid outlet device body 1.

[0062] The first drive mechanism can be either a manual drive mechanism or an electric drive mechanism.

[0063] In some exemplary embodiments, the first driving mechanism includes a first driving member and a first transmission assembly. The first transmission assembly is connected to the first driving member and the locking member 31, and is configured to drive the locking member 31 to move under the drive of the first driving member. The structural forms of the first driving member and the first transmission assembly are not limited and can be configured as needed.

[0064] Alternatively, the first drive mechanism may not include the first transmission assembly, and the first drive member may be directly connected to the locking member 31.

[0065] In some exemplary embodiments, the locking part includes a limiting groove 23 provided on the outer side wall of the liquid outlet cover assembly 2, such as... Figure 12 As shown. The locking element 31 includes a slider. The slider is slidably connected to the liquid dispensing device body 1 and is configured to slide relative to the liquid dispensing device body 1 along the depth direction of the limiting groove 23.

[0066] When the slider slides into the limiting groove 23, it supports and limits the liquid outlet cover assembly 2, preventing it from detaching from the liquid outlet device body 1 and thus locking the liquid outlet cover assembly 2. When the slider disengages from the limiting groove 23, the liquid outlet cover assembly 2 is unlocked and can then freely detach from the liquid outlet device body 1.

[0067] In some embodiments, such as Figure 17 and Figure 18 As shown, the limiting groove 23 is provided on the outer wall of the liquid outlet cover assembly 2. The depth direction of the limiting groove 23 is perpendicular to the thickness direction of the liquid outlet cover assembly 2. The liquid outlet cover assembly 2 is configured to enter and exit the mounting cavity 121 along its thickness direction. For example, when the liquid outlet cover assembly 2 is approximately cylindrical, the thickness direction of the liquid outlet cover assembly 2 is its axial direction, and the depth direction of the limiting groove is its radial direction.

[0068] Of course, the liquid outlet cover assembly 2 is not limited to a cylindrical shape; it can also be a quadrangular prism or other shapes. The liquid outlet cover assembly 2 is configured to enter and exit the mounting cavity 121 in a direction perpendicular to its thickness direction, i.e., side entry and side exit. The depth direction of the limiting groove 23 can also be parallel to the thickness direction of the liquid outlet cover assembly 2, as long as the limiting block can provide support and limiting for the liquid outlet cover assembly 2.

[0069] In some exemplary embodiments, such as Figure 3 , Figure 9 and Figure 11 As shown, the first transmission assembly includes a swing rod 32 and a pin 33. The swing rod 32 is oscillatingly connected to the liquid dispensing device body 1 via the pin 33. One end of the swing rod 32 engages with a slider to limit its movement, thereby causing the slider to slide relative to the liquid dispensing device body 1. The slider can reciprocate along the depth direction of the liquid dispensing cover assembly 2. The extension direction of the pin 33 can be perpendicular to the sliding direction of the slider.

[0070] The specific shape of the swing rod 32 is not limited; for example, it can be roughly straight, with a bushing 321 protruding in the middle. The pin 33 passes through the bushing 321 and is rotatably connected to the liquid dispensing device body 1. The limiting and matching method between the swing rod 32 and the slider is also not limited, as long as the swing of the swing rod 32 can drive the slider to slide.

[0071] In some embodiments, such as Figure 6 As shown, the slider has a first insertion hole 311, and one end of the swing rod 32 is inserted into the first insertion hole 311 and can swing relative to the first insertion hole 311. One end of the swing rod 32 can be smaller than the size of the first insertion hole 311 (clearance fit) so that the swing rod 32 is inserted into the first insertion hole 311 and can swing relative to the slider within a certain angle.

[0072] In some exemplary embodiments, such as Figure 3 As shown, the first transmission assembly also includes a push rod 34. The push rod 34 is slidably connected to the liquid dispensing device body 1, and one end of the push rod 34 is in a limiting engagement with the other end of the swing rod 32, configured to drive the swing rod 32 to swing relative to the liquid dispensing device body 1. The push rod 34 can slide reciprocally along the radial direction of the liquid dispensing cover assembly 2. The sliding direction of the push rod 34 can be consistent with the sliding direction of the linked slider.

[0073] The specific shape of the push rod 34 is not limited; for example, it can be roughly straight. The limiting and engagement method between the swing rod 32 and the push rod 34 is also not limited, as long as the sliding of the push rod 34 can drive the swing rod 32 to swing.

[0074] In some embodiments, such as Figure 6 As shown, one end of the push rod 34 is provided with a second insertion hole 341, and the other end of the swing rod 32 is inserted into the second insertion hole 341 and can swing relative to the second insertion hole 341. The other end of the swing rod 32 can be smaller than the size of the second insertion hole 341 (clearance fit) so that the swing rod 32 is inserted into the second insertion hole 341 and can swing relative to the push rod 34 within a certain angle.

[0075] In some exemplary embodiments, such as Figure 3 As shown, the first actuator includes a button 35. Figure 4 As shown, button 35 is provided with a drive block 351, drive block 351 is provided with a drive ramp 3511, and push rod 34 is provided with a mating ramp 3421, as... Figure 6 As shown. The driving ramp 3511 and the mating ramp 3421 engage to stop the movement of the push rod 34, so that the button 35 can drive the push rod 34 to slide, and the direction of movement of the button 35 is perpendicular to the direction of movement of the push rod 34. The mating ramp 3421 can be located at the other end of the push rod 34, or at other parts of the push rod, as long as it can reliably engage with the driving ramp 3511 to drive the push rod 34 to move.

[0076] Button 35 can be configured to move along the thickness direction of the liquid outlet cover assembly 2. Push rod 34 can be configured to slide along the depth direction of the limiting groove 23 of the liquid outlet cover assembly. Through the cooperation of the driving inclined surface 3511 and the mating inclined surface 3421, the pressing motion of button 35 in the thickness direction of the liquid outlet cover assembly 2 can be converted into the linear sliding motion of push rod 34 along the depth direction of the limiting groove 23. Furthermore, the cooperation of the two inclined surfaces (i.e., driving inclined surface 3511 and mating inclined surface 3421) helps to improve the reliability of the cooperation.

[0077] In other embodiments, the drive block 351 is provided with a drive ramp 3511, which engages with the push rod 34 to stop and make the button 35 able to drive the push rod 34 to slide, and the movement direction of the button 35 is perpendicular to the sliding direction of the push rod 34.

[0078] Alternatively, the push rod 34 is provided with a mating inclined surface 3421, and the drive block 351 is mated with the mating inclined surface 3421 to prevent it from moving, so that the button 35 can drive the push rod 34 to slide and the movement direction of the button 35 is perpendicular to the sliding direction of the push rod 34.

[0079] In other words, either the driving ramp 3511 or the mating ramp 3421 can be omitted; that is, by retaining only one of the driving ramp 3511 and the mating ramp 3421, the axial pressing motion of the button 35 can be converted into the radial linear sliding motion of the push rod 34. A single ramp simplifies the structure of the button 35 or the push rod 34, thereby reducing production costs.

[0080] In some embodiments, such as Figure 4 and Figure 6 As shown, the other end of the push rod 34 is provided with a third insertion hole 342, and a beveled surface 3421 is provided on the wall of the third insertion hole 342. At least a portion of the drive block 351 is inserted into the third insertion hole 342. This helps to prevent the drive block 351 from disengaging from the push rod 34 and improves the reliability of the fit between the button 35 and the push rod 34.

[0081] Of course, the first driving component is not limited to the structure of button 35. For example, it can also be operated by push button 54, knob, toggle, etc. By appropriately adjusting the first transmission component, the driving function of the first driving mechanism can also be achieved. Similarly, the locking component 31 is not limited to the structure of slider. For example, it can also be operated by snap-fit, etc. By appropriately adjusting the first driving mechanism, the locking function can also be achieved.

[0082] In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, there are multiple first transmission components, which are spaced apart circumferentially along the liquid outlet cover assembly 2. The button 35 has multiple drive blocks 351, each corresponding to a push rod 34. This facilitates balanced force distribution on the liquid outlet cover assembly 2, thereby improving its stability. The limiting groove 23 can be an annular groove, facilitating cooperation with multiple sliders. Compared to using multiple limiting grooves 23, this design reduces the precision requirements for the processing of the liquid outlet cover assembly 2.

[0083] In one embodiment, such as Figure 3 and Figure 4As shown, there are five first transmission components, which are evenly spaced along the circumference of the liquid outlet cover assembly 2. Five push rods 34 are arranged radially, and a button 35 is located in the middle of the five push rods 34 and is linked to them. The five push rods 34 are linked to five swing rods 32, and the five swing rods 32 are linked to five sliders. Therefore, by pressing the button 35, the five push rods 34 slide radially inward along the liquid outlet cover assembly 2. The five push rods 34 cause the ends of the five swing rods furthest from the sliders to swing inward, causing the ends of the five swing rods closest to the sliders to slide outward and disengage from the limiting groove 23 of the liquid outlet cover assembly 2. Thus, the liquid outlet cover assembly 2 can be freely detached from the liquid outlet device body 1, achieving disassembly.

[0084] In some exemplary embodiments, such as Figure 4 and Figure 6 As shown, the push rod 34 has a limiting protrusion 343 in the middle, and the liquid dispensing device body 1 has a stop portion 127. The limiting protrusion 343 and the stop portion 127 are arranged at intervals relative to each other. The first driving mechanism also includes a first elastic member 36 located between the limiting protrusion 343 and the stop portion 127. The first elastic member 36 is configured to store elastic potential energy during the process of the push rod 34 being pressed and slid by the button 35, so as to use its reset elastic force to drive the push rod 34 to reset. The first elastic member 36 can be, but is not limited to, a spring.

[0085] Thus, when button 35 is released, push rod 34 automatically resets under the reset force of the first elastic element 36. Since push rod 34 is linked to button 35 and swing rod 32, push rod 34 can also reset button 35 and swing rod 32; and since swing rod 32 is linked to slider, swing rod 32 can also reset slider. This achieves automatic reset of the first transmission assembly and button 35, i.e., the locking mechanism automatically resets to the locked state. Therefore, when it is necessary to disassemble the liquid outlet cover assembly 2, pressing button 35 unlocks it, and then the liquid outlet cover assembly 2 can be removed. Figures 12 to 14 As shown. Releasing button 35 will automatically reset the locking mechanism to the locked state. Alternatively, when installing the liquid outlet cover assembly 2, button 35 can be pressed to unlock it. After installing the liquid outlet cover assembly 2 in place, releasing button 35 will automatically reset the locking mechanism to the locked state, locking the liquid outlet cover assembly. Figures 15 to 16 As shown.

[0086] The number of first elastic elements 36 is equal to the number of push rods 34 and they correspond one-to-one. The limiting protrusion 343 can be a plate-shaped structure, and the limiting protrusion 343 can also be provided with a positioning post 3431. One end of the first elastic element 36 can be sleeved on the positioning post 3431 to avoid the first elastic element 36 from tilting or shifting, which helps to improve the reliability of the first elastic element 36.

[0087] Alternatively, the position of the first elastic element 36 can be changed. For example, the first elastic element 36 can cooperate with the button 35, thereby automatically resetting the locking mechanism by driving the button 35 to reset. Alternatively, the first elastic element 36 can cooperate with the swing lever 32 (using a torsion spring), thereby automatically resetting the locking mechanism by driving the swing lever 32 to reset. Alternatively, the first elastic element 36 can cooperate with the slider, thereby automatically resetting the locking mechanism by driving the slider to reset.

[0088] In some exemplary embodiments, the end of the slider near the liquid outlet cover assembly 2 is provided with a clearance ramp 312, such as... Figure 14 As shown, the avoidance slope 312 is configured to avoid the liquid outlet cover assembly 2 during the process of inserting the liquid outlet cover assembly 2 into the mounting cavity 121.

[0089] Thus, during the installation of the liquid outlet cover assembly 2, pressing the liquid outlet cover assembly 2 will move the slider to the unlocked position, as shown below. Figures 14 to 15 As shown, without needing to operate the first drive component, when the liquid outlet cover assembly 2 is installed in place, the slider can automatically reset to the locked position under the action of the first elastic element 36, as shown. Figure 16 As shown, the liquid outlet cover assembly 2 is locked. Therefore, the installation process of the liquid outlet cover assembly 2 only requires pressing it, greatly improving the ease of installation and enhancing the user's operating experience.

[0090] In some exemplary embodiments, the dispensing device further includes a release mechanism. The release mechanism is configured to apply a force to the dispensing cover assembly 2 after the locking mechanism is switched to the unlocked state, so as to drive the dispensing cover assembly 2 to release from the dispensing device body 1.

[0091] This helps reduce the difficulty of disassembling the liquid outlet cover assembly 2, improves the ease of disassembly of the liquid outlet cover assembly 2, and enhances the user's operating experience.

[0092] In some exemplary embodiments, the release mechanism is located upstream of the liquid outlet cover assembly 2. For example... Figure 3 As shown, the ejection mechanism includes a top cover 41 and a second elastic member 42. The top cover 41 is engaged with the liquid outlet cover assembly 2 for a stop-fitting action. Figure 6 As shown. The second elastic element 42 is confined within the body 1 of the liquid outlet device and cooperates with the top cover 41 so that the top cover 41 can exert a pushing force on the liquid outlet cover assembly 2 by utilizing its restoring elastic force.

[0093] In this way, when in use, the top cover 41 can firmly hold the liquid outlet cover assembly 2, which helps to prevent the liquid outlet cover assembly 2 from loosening, thereby improving the reliability of the liquid outlet device. When it is necessary to disassemble the liquid outlet cover assembly 2, after switching the locking mechanism to the unlocked state, the second elastic element 42 releases its elastic potential energy, which can assist in pushing the liquid outlet cover assembly 2 out without the user having to pull it out forcefully, thus improving the convenience of disassembling the liquid outlet cover assembly 2 and enhancing the user's operating experience.

[0094] In addition, with the assistance of the release mechanism, users can remove the liquid outlet cover assembly 2 by looking upwards. When the liquid outlet cover assembly 2 pops upwards, it can be removed. This helps to prevent the liquid outlet cover assembly 2 from falling directly to the ground and breaking or injuring the user when it is removed downwards.

[0095] like Figure 3 As shown, there can be multiple second elastic elements 42. Multiple second elastic elements 42 are arranged at intervals, which helps to balance the force on the top cover 41 and prevent tilting.

[0096] In some exemplary embodiments, such as Figure 6 As shown, the top cover 41 and the body 1 of the liquid outlet device enclose a first liquid flow channel 43 that communicates with the liquid inlet 122. The top cover 41 and the liquid outlet cover assembly 2 enclose a second liquid flow channel 44. The top cover 41 is provided with a through hole 411 that connects the first liquid flow channel 43 and the second liquid flow channel 44. The second liquid flow channel 44 communicates with the liquid outlet cavity through the first liquid outlet 21 or the second liquid outlet 22. The second elastic member 42 is located inside the first liquid flow channel 43 and abuts against the top cover 41. The first liquid flow channel 43 can be, but is not limited to, a circular channel, and the second liquid flow channel 44 can be, but is not limited to, a circular channel. This facilitates uniform liquid entry into the liquid outlet cavity, and thus facilitates uniform liquid exit.

[0097] In some embodiments, such as Figure 6 As shown, the circumferential edge of the top cover 41 is provided with a through flange 412, which abuts against the circumferential end of the liquid outlet cover assembly 2 and together with the liquid outlet cover assembly 2 forms a second liquid flow channel 44.

[0098] In some embodiments, such as Figure 13 As shown, the liquid dispensing device body 1 is provided with a limiting protrusion 1213, the top cover 41 is provided with a limiting groove 413, one end of the second elastic member 42 is sleeved on the limiting protrusion 1213 and tightly fitted with the limiting protrusion 1213, and the other end of the second elastic member 42 is limited in the limiting groove 413 and tightly fitted with the limiting groove 413.

[0099] In this way, the second elastic element 42 can be well limited, which is beneficial to improving the reliability of the second elastic element 42. Furthermore, the limitation imposed by the second elastic element 42 also helps to prevent the top cover 41 from falling out of the liquid outlet device body 1 after the liquid outlet cover assembly 2 is disassembled.

[0100] Of course, after the liquid outlet cover assembly 2 is disassembled, the top cover 41 can also be pulled out forcefully to clean it.

[0101] In some exemplary embodiments, such as Figure 3 and Figure 19 As shown, the liquid dispensing device body 1 includes: an outer shell 11 and an inner frame assembly. The inner frame assembly is fixed inside the outer shell 11. The inner frame assembly is provided with a mounting cavity 121 and a liquid inlet 122.

[0102] In some exemplary embodiments, such as Figure 3 As shown, the inner frame assembly includes an inner frame 12 and a fixing plate 13. The inner frame 12 has a mounting cavity 121, and one end of the inner frame 12 is open, forming a mounting opening 1211 of the mounting cavity 121 (e.g., Figure 4 (As shown). The liquid outlet cover assembly 2 is configured to enter and exit the mounting cavity 121 through the mounting port 1211.

[0103] The side wall of the mounting cavity 121 is provided with a liquid inlet 122. A fixing plate 13 is located on the side of the inner frame 12 opposite to the mounting inlet 1211 and is fixedly connected to the inner frame 12. The fixing plate 13 can be fixedly connected to the inner frame 12 using fasteners such as screws. Figure 3 As shown. There can be multiple fasteners, spaced circumferentially along the liquid outlet cover assembly 2. These fasteners can be staggered with the multiple push rods 34 of the locking mechanism.

[0104] The locking mechanism of the liquid dispensing device body 1 is installed on the inner frame assembly.

[0105] In some embodiments, such as Figure 9 As shown, a clearance space 126 is provided between the fixed plate 13 and the inner frame 12. A sliding groove 1261 is provided within the clearance space 126. The sliding groove 1261 is configured to guide the push rod 34 of the locking mechanism, which helps improve the sliding reliability of the push rod 34. Furthermore, the fixed plate 13 can limit the push rod 34, helping to prevent it from disengaging. The number of sliding grooves 1261 is equal to the number of push rods 34 and they correspond one-to-one.

[0106] In some embodiments, such as Figure 4 and Figure 6As shown, the fixing plate 13 is provided with an avoidance opening 131, which is configured to avoid the button 35 and the push rod 34 of the locking mechanism near the end of the button 35, so as to ensure that the button 35 and the push rod 34 can reliably cooperate. The housing 11 is provided with an operating notch 114 that corresponds to and communicates with the avoidance opening 131, such as Figure 6 As shown, the operating notch 114 is designed to avoid the button 35, ensuring that the button 35 can be exposed for easy user operation. The avoidance opening 131 can be a circular opening. The operating notch 114 can be a circular opening, and the area of ​​the operating notch 114 can be smaller than the area of ​​the avoidance opening 131.

[0107] In some embodiments, the outer side wall of the inner frame 12 is provided with a pin hole 125, such as Figure 3 As shown, the pin holes 125 are configured to mount the pins 33 of the locking mechanism. The number of pin holes 125 is equal to the number of pins 33 and they correspond one-to-one.

[0108] In some embodiments, such as Figure 3 As shown, the outer wall of the inner frame 12 is provided with a swing groove 124, which is configured to accommodate the swing rod 32 of the locking mechanism. The number of swing grooves 124 is equal to the number of swing rods 32 and they correspond one-to-one. The swing grooves 124 are connected to the pin holes 125 and the bushings 321 of the swing rods 32. One end of the swing groove 124 near the slide groove 1261 is connected to the slide groove 1261 to facilitate the limiting engagement between the push rod 34 and the swing rod 32.

[0109] In some embodiments, such as Figure 3 As shown, the outer wall of the inner frame 12 is provided with a first sliding hole 123 that connects to the mounting cavity 121. The first sliding hole 123 is configured to accommodate the slider of the locking mechanism. The number of first sliding holes 123 is equal to the number of sliders and corresponds one-to-one. The first sliding hole 123 is connected to the end of the swing groove 124 near the slider to facilitate the limiting engagement between the slider and the swing rod 32.

[0110] In some embodiments, such as Figure 13 As shown, the inner frame 12 is provided with a limiting protrusion 1213, which is configured to tightly fit with the second elastic element 42 of the release mechanism.

[0111] exist Figure 10 , Figure 12 , Figure 14 , Figure 15 , Figure 16 In the diagram, arrows indicate the movement directions of the locking mechanism components during the disassembly and installation of the liquid outlet cover assembly 2. The disassembly process of the liquid outlet cover assembly 2 begins from... Figure 10 The state begins, through Figure 12 state to Figure 13The disassembly is completed in the state 14. The installation process of the liquid outlet cover assembly 2 begins in state 14 and proceeds through... Figures 15 to 16 The installation is complete.

[0112] In some exemplary embodiments, such as Figure 3 and Figure 6 As shown, the liquid dispensing device also includes a first sealing ring 15, which is located between the liquid dispensing cover assembly 2 and the side wall of the mounting cavity 121 to prevent leakage from the outer circumferential side of the liquid dispensing cover assembly 2.

[0113] In some exemplary embodiments, such as Figure 6 As shown, the cross-section of the first sealing ring 15 is V-shaped, and the V-shaped opening of the first sealing ring 15 faces away from the liquid outlet end of the liquid outlet cover assembly 2. This helps to prevent the liquid outlet cover assembly 2 from detaching from the liquid outlet device body 1, thereby improving the stability of the liquid outlet cover assembly 2, and also helps to reduce the installation resistance of the liquid outlet cover assembly 2, making it easier to install the liquid outlet cover assembly 2 quickly and smoothly.

[0114] In some exemplary embodiments, such as Figure 3 As shown, the outer shell 11 is provided with a receiving cavity 111 with one end open. The liquid dispensing device body 1 also includes a decorative ring 14 provided at the opening end of the receiving cavity 111. The inner frame 12 is provided in the receiving cavity 111. The decorative ring 14 and the inner frame 12 are in a stop-fitting cooperation to restrict the inner frame assembly from coming out of the receiving cavity 111.

[0115] In some exemplary embodiments, such as Figure 7 As shown, the liquid dispensing device body 1 also includes a flow regulating zone 1284 connected to the liquid inlet 122, located upstream of the liquid inlet 122. The liquid dispensing device further includes a flow regulating mechanism configured to adjust the flow rate of the flow regulating zone 1284, thereby regulating the inlet and outlet flow rates of the liquid dispensing chamber. In this way, the liquid dispensing flow rate of the device is adjustable, easily meeting different user needs and improving the user experience.

[0116] In some exemplary embodiments, such as Figure 7 and Figure 21 As shown, the flow regulation zone 1284 is provided with a flow regulation port 1285. The flow regulation mechanism includes: a flow regulation component 51 and a second drive mechanism.

[0117] The flow regulating component 51 is movably connected to the liquid outlet device body 1. The flow regulating component 51 is provided with a liquid-blocking part 511, such as... Figure 7 and Figure 21 As shown, the liquid-blocking part 511 is located at the flow regulating port 1285 and is configured to adjust the opening of the flow regulating port 1285 to regulate the inlet flow rate and outlet flow rate of the outlet chamber. The second drive mechanism is connected to the flow regulating member 51 and is configured to drive the flow regulating member 51 to move relative to the outlet device body 1.

[0118] This allows for stepless adjustment of the opening of the flow control port 1285 (i.e., continuous adjustment), enabling continuous variation of the liquid flow rate from 0 to 100%, which improves the user experience.

[0119] The second drive mechanism can be either a manual drive mechanism or an electric drive mechanism.

[0120] In some exemplary embodiments, the second driving mechanism includes a second driving member and a second transmission assembly. The second transmission assembly is connected to the second driving member and the flow regulating member 51, and is configured to drive the flow regulating member 51 to move under the drive of the second driving member. The structural forms of the second driving member and the second transmission assembly are not limited and can be configured as needed.

[0121] Alternatively, the second drive mechanism may not include the second transmission assembly, and the second drive component may be directly connected to the flow regulating component 51.

[0122] In some exemplary embodiments, the flow regulating member 51 is rotatably connected to the liquid dispensing device body 1, and the second transmission assembly includes: a rotating plate 52 and a pusher plate 53, such as... Figure 3 , Figure 7 , Figure 22 and Figure 23 As shown.

[0123] One end of the rotating plate 52 is fixedly connected to or tightly fitted with the flow regulating component 51, configured to drive the flow regulating component 51 to rotate, and the other end of the rotating plate 52 is provided with a mating hole 521 (e.g. Figure 23 As shown). The push plate 53 is provided with a limiting shaft 531 (as shown). Figure 9 and Figure 23 As shown, the limiting shaft 531 is inserted into the mating hole 521 and can rotate and slide relative to the mating hole 521. The push plate 53 is slidably connected to the liquid dispensing device body 1 and is configured to drive the rotating plate 52 to rotate under the drive of the second driving member.

[0124] The rotating plate 52 and the push plate 53 form a crank-connecting rod mechanism, which can convert the linear motion of the push plate 53 into the rotational motion of the rotating plate 52, and then drive the flow regulating component 51 to rotate.

[0125] In some exemplary embodiments, the second driving component includes a push button 54 that is slidably connected to the liquid dispensing device body 1. The push button 54 is tightly fitted or fixedly connected to the push plate 53, which has a simple structure and is easy and convenient to operate.

[0126] Alternatively, the second transmission component can be omitted, and the second driving component can be set as a knob. The knob is rotatably connected to the liquid outlet device body 1, and the knob is directly fixedly connected to or tightly fitted to the flow regulating component 51, directly driving the flow regulating component 51 to rotate.

[0127] Alternatively, the second drive mechanism can also adopt other structural forms, as long as it can drive the flow regulating component 51 to adjust the flow rate.

[0128] In some exemplary embodiments, the liquid dispensing device body 1 is provided with a handle, and the flow regulating area 1284 is disposed within the handle. The handle includes a handle body 128 and a rear cover 129, as shown below. Figure 7 As shown. The handle body 128 is provided with a first mounting groove 1281, as... Figure 20 and Figure 21 As shown. The rear cover 129 is placed over the opening end of the first mounting groove 1281, and together with the first mounting groove 1281, forms the flow adjustment area 1284. This facilitates the installation of the flow adjustment component 51.

[0129] like Figure 7 As shown, the bottom wall of the first mounting groove 1281 is recessed with a rotating groove 1282. The flow regulating component 51 is provided with a rotating part 512, which is rotatably limited in the rotating groove 1282. This helps to prevent the flow regulating component 51 from tilting during rotation and improves the reliability of the flow regulating component 51.

[0130] like Figure 21 As shown, the first mounting groove 1281 has a flow regulating port 1285 on its side wall near the liquid outlet cover assembly 2. The bottom wall of the rotating groove 1282 has a fourth insertion hole 1283, as shown. Figure 7 As shown, the bottom of the rotating part 512 is provided with an insertion part 513, which is inserted into the fourth insertion hole 1283 and is fixedly connected or tightly fitted with the rotating plate 52.

[0131] The insertion part 513 can be, but is not limited to, an elastic snap-fit ​​arranged opposite each other. The rotating part 512 can be, but is not limited to, a stepped cylinder. The liquid-retaining part 511 can be, but is not limited to, an arc-shaped plate structure.

[0132] In some exemplary embodiments, such as Figure 3 As shown, the handle also includes a handle housing 112 and a decorative cover 113. The handle body 128 and the rear cover 129 are fitted into the handle housing 112. The handle housing 112 and the handle body 128 together form a second mounting groove 1122, as shown. Figure 7 As shown. The handle housing 112 is provided with a mounting notch 1121 that communicates with the second mounting groove 1122, as shown. Figure 4 As shown. The rotating plate 52 and the push plate 53 are disposed within the second mounting groove 1122. The decorative cover 113 is disposed at the mounting notch 1121, and the decorative cover 113 has a second sliding hole 1131, as shown. Figure 4 As shown. The push button 54 is equipped with a push shaft 541, as... Figure 7 As shown, the push shaft 541 passes through the second sliding hole 1131 and the mounting notch 1121 and is fixedly connected to or tightly fitted with the push plate 53.

[0133] This facilitates the assembly of the push plate 53 and the rotating plate 52, and also helps to improve the aesthetics of the liquid outlet device.

[0134] In some exemplary embodiments, such as Figure 3 As shown, the handle also includes a liquid inlet pipe 16, which is inserted into the handle housing 112 and connected to the flow control area 1284.

[0135] In some embodiments, such as Figure 3 As shown, the handle housing 112 is disposed on the outer shell 11 of the liquid dispensing device body 1. The handle body 128 can be disposed on the inner frame 12 of the liquid dispensing device body 1. By reasonably controlling the length of the handle body 128, the handle body 128 of the inner frame 12 can be inserted obliquely into the handle housing 112, and then the cylindrical part of the inner frame 12 can be inserted into the receiving cavity 111 of the outer shell 11. Alternatively, the mounting notch 1121 of the handle housing 112 can also communicate with the receiving cavity 111, so that the handle body 128 of the inner frame 12 can enter the handle housing 112 through the mounting notch 1121 of the handle housing 112, thereby reducing the assembly difficulty of the inner frame 12 and the outer shell 11.

[0136] Alternatively, the handle body 128 can also be located in the liquid inlet pipe 16, in which case the relevant components of the flow regulating mechanism are installed in the liquid inlet pipe 16 to reduce the assembly difficulty of the inner frame 12 and the outer shell 11.

[0137] In some exemplary embodiments, such as Figure 7 As shown, a second sealing ring 55 is provided between the rotating part 512 and the wall of the rotating groove 1282. This helps to prevent water in the flow regulating area 1284 from leaking out through the rotating groove 1282 and the fourth insertion hole 1283, thus improving the sealing performance of the liquid outlet device.

[0138] In some exemplary embodiments, such as Figure 3 and Figure 7 As shown, the rear cover 129 is provided with guide ribs 1291, which are configured to guide the rotation of the liquid-blocking part 511. The guide ribs 1291 can be arc-shaped. This helps to prevent the flow regulating component 51 from tilting during rotation and improves the reliability of the flow regulating component 51.

[0139] In summary, the working principle of the shower head provided in this application embodiment is as follows: During operation, water flows into the flow adjustment zone 1284 through the inlet pipe 16. The push button 54 pushes the push plate 53, causing the rotating plate 52 to rotate, thereby driving the flow adjustment component 51 to rotate accordingly. The rotation of the flow adjustment component 51 can adjust the opening degree of the flow adjustment port 1285 (e.g., ...). Figure 20 and Figure 21 As shown in the figure, the water inlet flow rate can be adjusted, and the water outlet flow rate of each water outlet function can be adjusted from 0 to 100%.

[0140] exist Figures 5 to 8 In the diagram, arrows indicate the direction of water flow. Water flows through the regulating zone 1284 and then into the first flow channel via the inlet 122. It then enters the second flow channel through the through-hole 411 of the top cover 41, and finally flows into the outlet chamber via the first or second outlet 21 or the second outlet 22 of the outlet cover assembly 2, ultimately being discharged. The outlet cover assembly 2 is designed as a double-sided, fully covered water outlet assembly, allowing for switching between different water outlet functions. Both sides of the outlet cover assembly 2 can be designed with any different water spray patterns, and both can fully cover the water outlet without area limitations. One side can be designed with small holes for water outlet, and the other with large holes. With large holes, dirt flows out easily and is less prone to clogging. With small holes, dirt does not flow out easily and is prone to clogging. When the small hole is clogged, the outlet cover assembly 2 can be flipped to perform backwashing, allowing water to flow into the small hole from the front, dislodging the blockage and allowing it to flow out through the large hole, achieving a backwashing descaling effect.

[0141] Therefore, the shower head provided in this application embodiment has the following advantages: 1) The flow rate can be adjusted by pushing the push button to rotate the flow regulating component, thereby adjusting the opening size of the flow regulating port. The structure is simple and reliable, stepless adjustment is possible, operation is simple and convenient, and the feel is light; 2) The liquid outlet cover assembly can be easily disassembled and installed by pressing the button, which is convenient for switching and cleaning; 3) The liquid outlet assembly is fully covered on both sides, and both sides can be designed with any different water spray, and both can fully cover the water spray, without area restriction, to meet the user's need for a large area of ​​water spray; 4) The liquid outlet cover assembly can be flipped and switched for backwashing, so that the water flow backwashes the water outlet hole from the front, so that the blockage in the water outlet hole is removed from the water outlet hole and can flow out from the other side, achieving the backwashing descaling effect; 5) The liquid outlet cover assembly is detachable and can be modularly customized. Different liquid outlet cover designs and water spray functions can be configured to become different shower heads to meet the needs of different customers and save costs; 6) Different water spray functions can be switched, and the water flow rate of each water spray function can be adjusted.
