Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a water outlet component and a shower head. Background Technology

[0002] Water containing bubbles smaller than 100μm in diameter is called micro-nano bubble water. Human pores are generally between 80μm and 100μm in diameter. Micro-nano bubble water can penetrate into the pores, adsorbing dirt and skin metabolites and lifting them out, thus achieving deep and thorough cleansing. In addition, micro-nano bubble water also improves skin hydration, generates negative ions, breaks down stubborn oil, removes detergent residue, removes pesticide residue, and has antibacterial and bactericidal properties. Due to its advantages that ordinary water does not possess, it has attracted widespread attention and application.

[0003] When existing micro-nano bubble generators are used in combination with water-using devices such as shower heads and faucets, the gas-liquid mixture of water will all flow through the micro-nano bubble generator, achieving a single micro-nano bubble water output effect. This cannot achieve personalized water output effects, which will reduce the user's water experience. Summary of the Invention

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] The structural schematic diagrams of the water outlet component 10 and its components, the shower head 20 and its components provided in this embodiment are as follows: Figures 1 to 18 As shown.

[0064] Please see Figure 1 , Figure 3 , Figure 4as well as Figure 11 The water outlet assembly 10 of this embodiment includes a water inlet component 11, a shifting component 12, a micro-nano bubble generating component 13, and a water outlet component 14. The water inlet component 11 has a water inlet hole 1101. The shifting component 12 is movably connected to the water inlet component 11. The shifting component 12 has at least two guide holes 1201 and at least two guide grooves 1202, with the openings of the guide grooves 1202 facing away from the water inlet component 11, and each guide groove 1202 corresponding to one guide hole 1201. The micro-nano bubble generating component 13... It has an inlet 1301 and an outlet 1302, and the inlet 1301 is connected to one of the guide channels 1202; the outlet component 14 is arranged opposite to the inlet component 11 at intervals, and the outlet component 14 is provided with an outlet hole 1401, which is connected to the outlet 1302 and the other guide channel 1202 respectively; the outlet component 14 is connected to the shift component 12 to drive the shift component 12 to switch the guide hole 1201 to be connected to the inlet hole 1101 respectively. In this embodiment, the water inlet hole 1101 provided on the water inlet component 11 is connected to any one of at least two guide holes 1201, and each guide hole 1201 is connected to the guide channel 1202. Thus, gas-liquid mixed water can flow through the water inlet hole 1101 into the guide hole 1201 connected to the water inlet hole 1101, and then into the guide channel 1202 connected to the guide hole 1201. When the guide channel 1202, in which gas-liquid mixed water flows, is connected to the micro / nano bubble generating component 13, the gas-liquid mixed water in the guide channel 1202 flows into the micro / nano bubble generating component 13 from the water inlet 1301. In the micro / nano bubble generating component 13, depressurization occurs, and the water becomes micro / nano bubble water. Furthermore, because the water outlet 1302 is connected to the water outlet component 14... The water outlet 1401 is connected, so micro-nano bubble water will flow out from the water outlet 1401, thus obtaining micro-nano bubble water; when the water outlet component 14 is turned clockwise or counterclockwise, the water outlet component 14 will drive the shifting component 12 to rotate as well. The guide hole 1201 on the shifting component 12 that is connected to the water inlet 1101 will switch, switching to the water inlet 1101 being connected to another guide hole 1201, and the gas-liquid mixed water can flow in through the other guide hole 1201. In another guide channel 1202, since the other one is not connected to the micro-nano bubble generating component 13, ordinary gas-liquid mixed water can be obtained from the water outlet 1401; or switch to the water inlet 1101 spanning between the two guide channels 1201. At this time, the water inlet 1101 is connected to both guide channels 1201, so that micro-nano bubble water and gas-liquid mixed water can be obtained at the water outlet 1401 at the same time. Therefore, the water outlet component 10 of this embodiment has at least three water outlet functions.

[0065] Please see Figure 4 , Figure 7and Figure 8 In some embodiments, the guide hole 1201 includes a first hole 12011 and a second hole 12012, and the guide groove 1202 includes a first groove 12021 and a second groove 12022; wherein, the first hole 12011 communicates with the first groove 12021, the second hole 12012 communicates with the second groove 12022, and the water inlet 1301 communicates with the first groove 12021. In this embodiment, the shifting component 12 has two holes. By rotating the water outlet component 14 clockwise or counterclockwise, the shifting component 12 can be rotated to switch the water inlet 1101 back and forth between the first hole 12011 and the second hole 12012, so as to achieve communication between the water inlet 1101 and the first hole 12011 and / or the second hole 12012, thereby obtaining micro-nano bubble water, or gas-liquid mixed water, or simultaneously obtaining micro-nano bubble water and gas-liquid mixed water. Of course, in some embodiments, the flow guide hole 1201 is not limited to two holes, and the flow guide groove 1202 is not limited to two grooves. According to actual needs, the flow guide hole 1201 can be set to multiple holes and the flow guide groove 1202 can be set to multiple grooves corresponding to the number of flow guide holes 1201.

[0066] Please see Figure 3 and Figure 4 In some embodiments, the diameter of the inlet hole 1101 is greater than the distance between the two guide holes 1201 (i.e., the distance between the first hole 12011 and the second hole 12012), and less than the sum of the diameters of the two guide holes 1201 (i.e., less than the sum of the diameters of the first hole 12011 and the second hole 12012). This is beneficial for the water outlet assembly 10 to have three water outlet effects: micro-nano bubble water, gas-liquid mixed water, and simultaneously obtain micro-nano bubble water and gas-liquid mixed water.

[0067] Please see Figure 5 , Figure 6 and Figure 4 In some embodiments, the water inlet component 11 includes a main water inlet component 111 and a positioning pin 112. A water inlet hole 1101 is disposed on the main water inlet component 111, and one end of the positioning pin 112 is elastically connected to the main water inlet component 111, while the other end extends towards the shifting component 12. The shifting component 12 has shift grooves 1203, the number of which is the same as the number of guide holes 1201, and the opening of each shift groove 1203 faces the water inlet component 11 for the positioning pin 112 to be inserted into. Because the positioning pin 112 in this embodiment has an elastic function, it can elastically extend from the main water inlet component 111 into the shift groove 1203 or retract from the shift groove 1203 into the main water inlet component 111. This allows the shifting component 12 to lock when shifting is complete, thereby ensuring that the water inlet hole 1101 is fixedly connected to one of the guide holes 1201.

[0068] Please see Figure 5 , Figure 6 and Figure 4 In some embodiments, the main water inlet component 111 has a positioning protrusion 1112 and a receiving groove 1102. The positioning protrusion 1112 protrudes from the surface of the main water inlet component 111 facing away from the shifting component 12, thereby facilitating the fixation of the water inlet component 11 and providing a fulcrum for the rotation of the water outlet component 14 to achieve gear switching, so that the water inlet component 11 does not rotate while the water outlet component 14 and the shifting component 12 rotate. The opening of the receiving groove 1102 faces the shifting component 12, and the positioning pin 112 is received in the receiving groove 1102, facilitating the elastic extension and retraction of the positioning pin 112. In some embodiments, the water inlet hole 1101 is provided on the positioning protrusion 1112, so that when the water outlet component 10 is connected to the shower head 20 or faucet, the positioning protrusion 1112 can not only serve to connect to the shower head 20 or faucet, but also serve to provide a fulcrum and facilitate water inlet.

[0069] Please see Figure 5 , Figure 6 and Figure 4 In some embodiments, the water inlet component 11 further includes a first elastic seal 113, which is disposed at the end of the positioning protrusion 1112 facing the shifting component 12 and is arranged around the outer periphery of the water inlet hole 1101 and the guide hole 1201. By providing the first elastic seal 113, not only can the sealing effect of the water flow between the water inlet component 11 and the shifting component 12 be improved, but also the relative rotation between the water inlet component 11 and the shifting component 12 can be better buffered, reducing the frictional resistance between the two and improving the reliability of the connection between the water inlet component 11 and the shifting component 12.

[0070] Please see Figure 5 , Figure 6 and Figure 4 In some embodiments, the main water inlet component 111 is further provided with a first limiting protrusion 1111, which protrudes towards the shifting component 12; the shifting component 12 is provided with a limiting groove 1204, the opening of which faces the first limiting protrusion 1111 for the first limiting protrusion 1111 to be inserted. The structure of the first limiting protrusion 1111 and the limiting groove 1204 can control the rotation amplitude of the shifting component 12 relative to the water inlet component 11 within a certain range when shifting gears, without requiring the shifting component 12 to rotate significantly, thus facilitating quick gear shifting operations for the user.

[0071] In some embodiments, the limiting groove 1204 is an arc-shaped groove, and the first limiting protrusion 1111 is an arc-shaped strip protrusion that matches the arc-shaped groove. The length of the arc-shaped groove is greater than the length of the arc-shaped strip protrusion, so that when the shifting component 12 rotates to switch gears, the limiting groove 1204 and the first limiting protrusion 1111 will undergo relative displacement.

[0072] Please see Figure 7 , Figure 8 and Figure 4 In some embodiments, the shifting component 12 includes a shifting main component 121, a connecting component 122, and an elastic limiting component 123; wherein, the shifting main component 121 has a first end face 12101 and a second end face 12102, the first end face 12101 and the second end face 12102 are disposed opposite to each other; a first hole 12011 and a second hole 12012 are both formed on the shifting main component 121, a first groove 12021 and a second groove 12022 are also formed on the shifting main component 121, and the openings of the first groove 12021 and the second groove 12022 both face the second end face 12102; a water inlet component 11 is disposed on the first end face 12101, and the elastic limiting component 123 is disposed on the first end face 12101 to limit the water inlet component 11; the connecting component 122 is disposed on the second end face 12102, and the water outlet component 14 is connected to the connecting component 122. In some embodiments, the shifting main component 121 is a circular plate, and the connecting component 122 is a hollow circular frame. The connecting component 122 is connected to the outer periphery of the shifting main component 121 and extends away from the first end face 12101 to the second end face 12102 from the shifting main component 121. The water outlet component 14 is connected to the connecting component 122 at the end of the connecting component 122 away from the shifting main component 121. Thus, the shifting main component 121, the connecting component 122, and the water outlet component 14 together form a closed space that can accommodate the microbubble generating component. The shifting component 12 is designed in such a structure that it can have a good connection with both the water inlet component 11 and the water outlet component 14, thereby improving the compactness and reliability of the water assembly 10.

[0073] Please see Figure 7 , Figure 8 , Figure 6 and Figure 4In some embodiments, the shifting main component 121 is further provided with a transition groove 1206, which is located between the first groove 12021 and the second groove 12022, and the opening of the transition groove 1206 faces the second end face 12102. The transition groove 1206 facilitates the insertion and positioning of the positioning pin 112 when the shifting component 12 rotates relative to the water inlet component 11 to be between the first hole 12011 and the second hole 12012, so as to achieve the simultaneous acquisition of micro-nano bubble water and gas-liquid mixed water.

[0074] Please see Figure 2 , Figure 7 , Figure 8 and Figure 4 In some embodiments, there are multiple elastic limiting members 123, all evenly distributed on the first end face 12101 of the shift main member 121, and arranged around the side end of the water inlet member 11, thereby positioning the water inlet member 11. In some embodiments, there are six elastic limiting members 123, arranged in pairs, for a total of three groups. The distance between two elastic limiting members 123 in the same group is smaller than the distance between two adjacent groups of elastic limiting members 123, thereby improving the reliability of the limiting. Of course, in some embodiments, the number of elastic limiting members 123 is not limited to six; for example, it can be four, eight, or ten, etc.

[0075] Please see Figure 7 , Figure 8 and Figure 4 In some embodiments, each elastic limiting member 123 includes an elastic connecting arm 1231 and a limiting boss 1232. One end of the elastic connecting arm 1231 is connected to the shift main member 121, and the other end is connected to the limiting boss 1232; the limiting boss 1232 protrudes towards the central axis of the water inlet member 11. In this embodiment, because the elastic connecting arm 1231 can undergo elastic deformation, it facilitates the assembly or disassembly of the water inlet member 11 and the shift member 12. The limiting boss 1232 effectively limits the water inlet member 11 to the first end face 12101 of the shift member 12, preventing the water inlet member 11 from falling off the first end face 12101. This ensures that the water inlet member 11 and the shift member 12 have both a good connection and a certain degree of mobility, ultimately achieving a good movable connection between them.

[0076] Please see Figure 2 , Figure 7 , Figure 8 and Figure 4In some embodiments, the limiting boss 1232 has a guide surface 12321 and a limiting surface 12322; wherein, the limiting surface 12322 faces the first end face 12101 and abuts against the water inlet component 11; the guide surface 12321 is connected to the edge of the limiting surface 12322 away from the elastic connecting arm 1231, and extends away from the water inlet component 11 with a gradually decreasing distance relative to the elastic connecting arm 1231 from the connection point with the limiting surface 12322, and is connected to the elastic connecting arm 1231. In some embodiments, the elastic connecting arm 1231 has a top surface 12311, the top surface 12311 facing away from the first end face 12101, and the top surface 12311 and the limiting surface 12322 are spaced apart and opposite to each other, and the guide surface 12321 is connected between the top surface 12311 and the limiting surface 12322. The structural design of the limiting boss 1232 not only makes it easy to install the water inlet component 11 on the first end face 12101 of the shift component 12, but also allows for good fixation of the water inlet component 11. In addition, due to the presence of the elastic connecting arm 1231, the water inlet component 11 can also be easily disassembled.

[0077] Please see Figure 9 , Figure 10 and Figure 11 The micro-nano bubble generating component 13 includes a core 131 and a shell 132. The shell 132 has a channel 1320, with an inlet 1301 and an outlet 1302 respectively located on the shell 132. The channel 1320 connects the inlet 1301 and the outlet 1302, and its diameter gradually increases from the inlet 1301 to the outlet 1302. A portion of the core 131 is inserted into the channel 1320 from the outlet 1302, forming a flow channel 1300. A drain hole 1310 is provided on the core 131, communicating with the flow channel 1300 and the outlet 1401, thus connecting the outlet 1302 and the outlet 1401. As the gas-liquid mixed water flows into the micro-nano bubble generating component 13 from the water inlet 1301, it gradually depressurizes, thereby generating micro-nano bubble water. Therefore, the structural arrangement of the micro-bubble generating component enables the water output component 10 to obtain micro-nano bubble water.

[0078] Please see Figure 9 , Figure 10 and Figure 11In some embodiments, the housing 132 includes a housing body 1321 and a conical protrusion 1322. The housing body 1321 is connected to the shifting component 12 and covers the first groove 12021, thus isolating the first groove 12021 and the second groove 12022 from each other to prevent water leakage. The apex of the conical protrusion 1322 is connected to the housing body 1321, and the bottom of the conical protrusion 1322 faces away from the housing body 1321. A water inlet 1301 is located on the housing body 1321, a water outlet 1302 is located at the bottom of the conical protrusion 1322, and a channel 1320 is located within the conical protrusion 1322. Of course, the structure with channel 1320 is not limited to the conical protrusion 1322. It can also be a cylindrical protrusion. Channel 1320 can also be set in a cylindrical protrusion. In addition, it can be other shapes or other structures, as long as the diameter of channel 1320 can gradually increase from the inlet 1301 to the outlet 1302, so as to facilitate the partial insertion of core 131 in channel 1320 to form flow channel 1300.

[0079] Please see Figure 9 , Figure 10 and Figure 11 In some embodiments, the housing 132 further includes a support portion 1323, which is connected to the housing body 1321 and extends toward the core 131 to support the housing 132 and the core 131.

In some embodiments, the support portion 1323 is a support column, and there are multiple support columns spaced apart on the surface of the housing 132 facing the core 131 to further improve the structural reliability of the micro / nano bubble generating component 13. In some embodiments, there are three support columns spaced apart, which effectively improves the structural reliability of the micro / nano bubble generating component 13. Of course, the number of support columns is not limited to three; it can be set according to actual needs. For example, there can be one support column, where the support column and the conical protrusion 1322 work together to ensure the structural reliability of the micro / nano bubble generating component 13. Alternatively, the number of support columns can be two, four, or other numbers.

[0080] Please see Figure 9 , Figure 10 and Figure 11 In some embodiments, the core 131 includes a base 1311 and a cone 1312; wherein the cone 1312 is connected to the base 1311 and extends from the base 1311 toward the inlet 1301 and is inserted into the channel 1320, and the side of the cone 1312 and the wall of the channel 1320 enclose a flow channel 1300; a drain hole 1310 is provided on the base 1311 and communicates with the outlet 1302.

[0081] Please see Figure 9 , Figure 10 and Figure 11 In some embodiments, the core 131 further includes a limiting plate 1313, which is disposed on the base 1311 and surrounds the outer periphery of the cone 1312 to limit the conical protrusion 1322, and can effectively fix the annular sealing ring 133 on the annular groove 13220.

[0082] Please see Figure 9 , Figure 10 and Figure 11 In some embodiments, the core 131 further includes a diversion connection portion 1314, which is disposed between the base 1311 and the cone 1312 to connect the base 1311 and the cone 1312. In some embodiments, there are multiple diversion connection portions 1314, with adjacent diversion connection portions 1314 spaced apart, forming a drain hole 1310 by the adjacent two diversion connection portions 1314, the cone 1312, and the base 1311. By providing the diversion connection portions 1314, the micro-nano bubble water flowing out of the flow channel 1300 can be divided into multiple streams, improving the uniformity of the micro-nano bubble water output and avoiding uneven water pressure distribution. In some embodiments, there are four diversion connection portions 1314; however, the number of diversion connection portions 1314 is not limited to four, and can also be three, five, or six, etc.

[0083] Please see Figure 9 , Figure 10 and Figure 11 In some embodiments, the micro / nano bubble generating component 13 further includes an annular sealing ring 133, which is disposed between the housing 132 and the core 131 to seal the micro / nano bubble generating component 13, thereby improving the sealing performance of the flow channel 1300 and preventing water from seeping out from the connection between the housing 132 and the core 131, thus affecting the quality of the micro / nano bubble water. In some embodiments, an annular groove 13220 is provided on the side of the conical protrusion 1322, and the annular groove 13220 is disposed at the end of the conical protrusion 1322 away from the housing body 1321 for mounting the annular sealing ring 133. Of course, in some embodiments, the annular groove 13220 is not limited to being disposed on the conical protrusion 1322, but can also be disposed on the core 131, as long as it can achieve the sealing of the micro / nano bubble generating component 13.

[0084] Please see Figure 12 and Figure 4In some embodiments, the water outlet component 14 includes a water outlet element 141 and a hollow cover 142, wherein a water outlet hole 1401 is provided on the water outlet component 14, the water outlet element 141 is connected to the hollow cover 142 and covers the hollow portion of the hollow cover 142, and the hollow cover 142 is connected to the shifting component 12.

By providing the diversion section 1411, on the one hand, the water outlet 1401 is divided into two regions, such as a first region and a second region. The water outlet 1401 in the first region is connected to the drain hole 1310 of the micro-nano bubble generating component 13, so that micro-nano bubble water flows out from part of the water outlet 1401, while the water outlet 1401 in the second region is directly connected to the second tank 12022, and the gas-liquid mixed water flows out from the water outlet 1401 in the second region. On the other hand, it also ensures that there is a certain distance between the micro-nano bubble generating component 13 and the water outlet 14, which is beneficial for the micro-nano bubble water discharged from the drain hole 1310 to be stabilized before flowing out from the water outlet 1401.

[0086] Please see Figure 12 and Figure 4 In some embodiments, the water outlet component 14 further includes a water outlet seal 143, which is also an elastic seal. The water outlet seal 143 is disposed between the shift component 12 and the hollow cover 142. By providing the water outlet seal 143, a good seal can be achieved between the water outlet component 14 and the shift component 12, preventing water from overflowing from between them.

[0087] Please refer to 4. Figure 7 , Figure 11 as well as Figure 5In some embodiments, the water outlet assembly 10 further includes a fastener 15, which is used to fix the micro-nano bubble generating component 13 and the shifting component 12, thereby ensuring that the micro-nano bubble generating component 13 and the shifting component 12 do not rotate relative to each other during shifting rotation. In some embodiments, the fastener 15 is a screw or bolt. Of course, the fixation between the micro-nano bubble generating component 13 and the shifting component 12 is not limited to being achieved by the fastener 15; they can also be fixed by welding or gluing. In some embodiments, the water inlet component 11 has a clearance hole 1103 for the fastener 15 to pass through, thereby fixing the water outlet assembly 10 to the shower head 20 or faucet. In some embodiments, the shift component 12 is provided with a first mounting hole 1205, and the micro-nano bubble generating component 13 is provided with a second mounting hole 13210. The fastener 15 passes through the second mounting hole 13210 into the first mounting hole 1205 and out through the clearance hole 1103, thereby fixing the shift component 12 and the micro-nano bubble generating component 13 together.

[0088] Please see Figure 1 , Figure 4 and Figure 13 , Figure 15 , Figure 16 and Figure 17 Based on the above-mentioned water outlet component 10, this embodiment of the invention also provides a shower head 20.

[0089] Specifically, the shower head 20 includes a shower head 21 and a water outlet assembly 10. The shower head 21 has a water inlet 2110 and a water outlet 2120. The shower head 21 has a groove 2121 inside, with the groove opening facing the water outlet assembly 10. The water outlet 2120 is connected to the groove 2121. The water outlet assembly 10 is connected to the shower head 21. A portion of the water inlet component 11 is inserted into the groove 2121, and a water inlet hole 1101 is located at the part of the water inlet component 11 inserted into the groove 2121 and is connected to the water outlet 2120. In this embodiment, since the water inlet component 11 is partially inserted into the slot 2121 and the water outlet 2120 is connected to the water inlet hole 1101, the gas-liquid mixed water flowing in from the water inlet 2110 can enter the water outlet component 10 through the water outlet 2120 and the water inlet hole 1101, and finally obtain the corresponding water from the water outlet hole 1401. More importantly, since the water inlet component 11 is partially inserted into the slot 2121, the water inlet component 11 is fixed. When the water outlet component 14 is rotated clockwise or counterclockwise, the shifting component 12 rotates with the water outlet component 14, while the water inlet component 11 remains fixed, thereby enabling the switching of the water outlet position of the water outlet component 10.

[0090] Please see Figure 13 and Figure 18In some embodiments, the shower head 21 includes a handle portion 211 and a mounting portion 212, which are connected. A water inlet 2110 is located at the end of the handle portion 211 away from the mounting portion 212. A water channel 2100 is provided in the handle portion 211. A slot 2121 is located at the end of the mounting portion 212 facing the water outlet assembly 10, and a water outlet 2120 is located in the slot 2121. The water channel 2100 connects the water inlet 2110 and the water outlet 2120, thereby fixing the water inlet component 11 and improving the reliability of the shower head 20 structure.

[0091] Please see Figure 4 , Figure 5 and Figure 16 In some embodiments, the portion of the water inlet component 11 that is inserted into the slot 2121 is a positioning protrusion 1112. The shower head 20 also includes a second elastic seal 22, which is disposed in the slot 2121 and surrounds the outer periphery of the positioning protrusion 1112. The second elastic seal 22 can achieve a good seal between the shower head 21 and the water inlet component 11, preventing the gas-liquid mixture of water flowing into the water inlet hole 1101 from overflowing from the gap between the shower head 21 and the water inlet component 11.

[0092] Please see Figure 18 and Figure 16 In some embodiments, the mounting part 212 has a fastening hole 2122, the opening of which faces the water outlet assembly 10 and matches the fastener 15. By providing the fastening hole 2122, the water outlet assembly 10 can be installed on the shower head 21.

[0093] The shower head 20 provided in this embodiment of the invention can, when used in conjunction with a water heater, obtain micro-nano bubble water, gas-liquid mixed water, or a mixture of micro-nano bubble water and gas-liquid mixed water by switching the setting of the water outlet component 10 if the gas-liquid mixed water function of the water heater is activated; if the gas-liquid mixed water function is not activated, ordinary water can be obtained. It can realize multiple water outlet functions, provide users with personalized water outlet effects, and thus help improve the user's water experience.

[0094] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
