Detailed Implementation
[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0029] This utility model relates to a water outlet structure with adjustable pulse frequency, including a main body 100.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the main body 100 is provided with a water cavity 110, which has a water inlet 111, a first water-blocking part 112, a second water-blocking part 113, a first water outlet 116, and a second water outlet 117. The first water-blocking part 112 and the second water-blocking part 113 can be symmetrically arranged in the water cavity 110. A first channel 121 is formed between the first water-blocking part 112 and the second water-blocking part 113. A second channel 122 is formed between the side wall of the first water-blocking part 112 away from the first channel 121 and the cavity wall of the water cavity 110. A third channel 123 is formed between the side wall of the second water-blocking part 113 away from the first channel 121 and the cavity wall of the water cavity 110. Figure 3As shown, the inlet 111 is located on the upper side of the water cavity 110, and the first water-blocking part 112 and the second water-blocking part 113 are symmetrically distributed on the left and right sides of the water cavity 110. The upper end of the first channel 121 is directly connected to the inlet 111, the upper ends of the second channel 122 and the third channel 123 are both connected to the upper end of the first channel 121, and the lower ends of the second channel 122 and the third channel 123 are both connected to the lower end of the first channel 121. The first channel 121 and the second channel 122 form an annular channel surrounding the first water-blocking part 112, and the first channel 121 and the third channel 123 form an annular channel surrounding the second water-blocking part 113. The first stop block 114 and the second stop block 115 are both located downstream of the first channel 121, the first stop block 114 is located below the first water-blocking part 112, and the second stop block 115 is located below the second water-blocking part 113. Both the first outlet 116 and the second outlet 117 are located downstream of the first channel 121. The first outlet 116 is located below the first water-blocking part 112, and the second outlet 117 is located below the second water-blocking part 113. The first baffle 114 is located between the first water-blocking part 112 and the first outlet 116, and the second baffle 115 is located between the second water-blocking part 113 and the second outlet 117. A partition can be installed between the first outlet 116 and the second outlet 117 for separation. When water is supplied, external water is injected into the first channel 121 through the inlet 111. According to the Coanda effect, the water randomly flows along the side wall of one of the first water-blocking parts 112 and the second water-blocking part 113. The following explanation takes the initial flow of water along the first water-blocking part 112 in the first channel 121 as an example. Most of the water in the first channel 121 flows along the side wall of the first water-blocking part 112. The water is blocked by the first baffle 114 and flows back into the second channel 122. Then, it flows back to the upper end of the first channel 121 through the second channel 122, increasing the water pressure on the side where the first water-blocking part 112 is located. Part of the water flowing along the side wall of the first water-blocking part 112 flows back into the second channel 122, while some is sprayed out through the first outlet 116. A small portion of the water initially flowing into the first channel 121 flows towards the second outlet 117 and the third channel 123. Because the water pressure on the side where the first water-blocking part 112 is located is higher than the water pressure on the side where the second water-blocking part 113 is located, water on the side where the first water-blocking part 112 is drawn towards the first water-blocking part 112. The water pressure in the third channel 123 is lower than the water pressure in the second channel 122. Due to the pressure difference, the water injected into the first channel 121 flows towards the side with lower pressure. This means that after the water enters the first channel 121, it flows along the side wall of the second water-blocking part 113. Under the obstruction of the second baffle 115, the water flows back into the third channel 123. The water in the third channel 123 flows back to the upper end of the first channel 121, and at this time, the water will be discharged to the outside from the second outlet 117.At this time, the water pressure on the side where the second water-blocking part 113 is located increases, drawing water from the side where the first water-blocking part 112 is located toward the second water-blocking part 113. The water injected into the first channel 121 then changes to flow along the first water-blocking part 112, and so on, so that the water is circulated and discharged from the first outlet 116 and the second outlet 117 to achieve the pulse water discharge effect.
[0031] like Figure 2 , Figure 4 and Figure 5As shown, the pulse frequency adjustable water outlet structure also includes a first regulating element 200 and / or a second regulating element 300. That is, the water outlet structure can have either the first regulating element 200 or the second regulating element 300 alone, or both simultaneously. When the first regulating element 200 is provided, it is movably inserted into the second channel 122. A portion of the first regulating element 200 is located outside the main body 100, and a portion is inserted into the second channel 122 perpendicular to the water flow direction, effectively intercepting the second channel 122. The first regulating element 200 can move relative to the second channel 122, changing its insertion depth and thus the interception area. The greater the insertion depth of the first regulating element 200 relative to the second channel 122, the larger the interception area, resulting in a smaller maximum flow rate through the second channel 122. The smaller the insertion depth of the first adjusting member 200 relative to the second channel 122, the smaller the interception area of the second channel 122, thus increasing the maximum water flow rate of the second channel 122. Specifically, based on the insertion depth of the first adjusting member 200, its two extreme positions are defined as the first position and the second position. When the first adjusting member 200 moves to the first position, its insertion depth is at its maximum, and it completely intercepts the second channel 122. At this point, the water flow rate of the second channel 122 is zero, meaning that water cannot pass through the second channel 122. When the first adjusting member 200 moves to the second position, it is not inserted into the second channel 122, and its interception area is zero. Therefore, the first adjusting member 200 has no interception effect on the second channel 122, and the water flow rate of the second channel 122 is at its maximum. Correspondingly, the second adjusting member 300 is similar to the first adjusting member 200. When the second adjusting member 300 is provided, it is movably inserted into the third channel 123. A portion of the second adjusting member 300 is located outside the main body 100, while a portion is inserted into the third channel 123 perpendicular to the water flow direction, effectively intercepting the water in the third channel 123. The second adjusting member 300 can move relative to the third channel 123, changing its insertion depth and thus the interception area. A greater insertion depth results in a larger interception area, thus reducing the maximum flow rate of the third channel 123. Conversely, a smaller insertion depth results in a smaller interception area, increasing the maximum flow rate. Specifically, based on the insertion depth of the second adjusting member 300, its two extreme positions are defined as the third position and the fourth position, respectively.When the second adjusting member 300 moves to the third position, its insertion depth is at its maximum, completely blocking the third channel 123. At this point, the water flow rate of the third channel 123 is zero, meaning water cannot pass through it. When the second adjusting member 300 moves to the fourth position, it is not inserted into the third channel 123, and its interception area is zero. Therefore, the second adjusting member 300 has no intercepting effect on the third channel 123, and the water flow rate of the third channel 123 is at its maximum.
[0032] When both the first adjusting member 200 and the second adjusting member 300 are provided, the first adjusting member 200 and the second adjusting member 300 can move synchronously or asynchronously relative to the main body 100. When the first adjusting member 200 and the second adjusting member 300 move synchronously, the interception areas of the first adjusting member 200 and the second adjusting member 300 on the second channel 122 and the third channel 123 simultaneously increase or decrease, and the change in the interception area of the two can be the same. For example... Figure 4 As shown, when the first adjusting member 200 is in the second position and the second adjusting member 300 is in the fourth position, the water flow rate of the second channel 122 and the third channel 123 is at its maximum. Water flows from the inlet 111 into the water chamber 110, achieving the pulse water output function, and the pulse frequency reaches its maximum value. When the first adjusting member 200 moves to the first position, the second adjusting member 300 simultaneously moves to the third position, and the water flow rate of the second channel 122 and the third channel 123 gradually decreases, causing the pulse water output frequency to gradually decrease. Figure 2 As shown, until the second channel 122 and the third channel 123 are completely intercepted, the main body 100 will not have a pulse water output effect, but will simply spray water synchronously from the first outlet 116 and the second outlet 117. When the first adjusting member 200 and the second adjusting member 300 move asynchronously, the change in the interception area of the first adjusting member 200 on the second channel 122 and the change in the interception area of the second adjusting member 300 on the third channel 123 can be opposite, that is, the interception area of the first adjusting member 200 on the second channel 122 increases, while the interception area of the second adjusting member 300 on the third channel 123 decreases, or the interception area of the first adjusting member 200 on the second channel 122 decreases, while the interception area of the second adjusting member 300 on the third channel 123 increases; it can also be that the interception areas of the first adjusting member 200 on the second channel 122 and the interception areas of the second adjusting member 300 on the third channel 123 both increase or decrease, but the amount of change is different. If the second channel 122 and the third channel 123 are not completely blocked, the channel with a larger blocked area will have a shorter spray time than the channel with a smaller blocked area, resulting in a difference in the spray time and spray volume of the first outlet 116 and the second outlet 117 under pulsed conditions.
[0033] When only the first adjusting member 200 is provided and the second adjusting member 300 is not provided, the first adjusting member 200 can adjust the interception area of the second channel 122 according to its own insertion position relative to the second channel 122. When the first adjusting member 200 moves to the first position, the second channel 122 is completely intercepted, and the third channel 123 is not intercepted at all. At this time, the above-mentioned water pressure difference circulation effect will not occur between the first water-blocking part 112 and the second water-blocking part 113. After the water passes through the first channel 121, it will be diverted to the first outlet 116 and the second outlet 117 for discharge. As the first adjusting member 200 gradually moves from the first position to the second position, the interception area of the first adjusting member 200 on the second channel 122 gradually decreases. The aforementioned water pressure difference cyclically changes between the first water-blocking part 112 and the second water-blocking part 113, achieving the effect of pulsed water output. Furthermore, as the intercepted area of the second channel 122 decreases, the water ejection time from the first outlet 116 gradually increases, and the pulsed water output frequency alternately ejected from the first outlet 116 and the second outlet 117 becomes faster. When only the second adjusting member 300 is provided without the first adjusting member 200, the water output adjustment principle is the same as when only the first adjusting member 200 is provided. In this case, the second channel 122 is not intercepted at all. When the second adjusting member 300 moves from the third position to the fourth position relative to the third channel 123, the interception area of the second adjusting member 300 on the third channel 123 gradually decreases from complete interception. When in the third position, water flows through the first channel 121 and is diverted to the first outlet 116 and the second outlet 117 for discharge. As it gradually moves to the fourth position, the water pressure difference between the first water-blocking part 112 and the second water-blocking part 113 gradually changes, achieving the effect of pulsed water discharge. Furthermore, as the intercepted area of the third channel 123 decreases, the time for water to spray from the second outlet 117 gradually increases, and the frequency of the pulsed water discharge from the first outlet 116 and the second outlet 117 alternately increases.
[0034] By utilizing the interception effect of the first regulating element 200 and the second regulating element 300, the main body 100 can achieve stepless adjustment of pulse water output, change the pulse frequency, and select pulse function and no pulse function to meet the different pulse water needs of users. The overall structure is simple and easy to use and adjust.
[0035] like Figure 1 and Figure 7As shown, this utility model also relates to a water outlet device, which can be a shower head, spray nozzle, spray gun, etc. The water outlet device utilizes the aforementioned pulse frequency adjustable water outlet structure to achieve stepless adjustment of different pulse water outlet effects. The water outlet device further includes a first flow channel 610 and a second flow channel 620. The first flow channel 610 is provided with a plurality of first water nozzles 611, and the second flow channel 620 is provided with a plurality of second water nozzles 621. The water spray patterns of the first water nozzles 611 and the second water nozzles 621 can be set to be the same or different. The first flow channel 610 is connected to the first water outlet 116, and the second flow channel 620 is connected to the second water outlet 117. When the main body 100 pulses water, the first water nozzles 611 and the second water nozzles 621 pulse water alternately. When the first adjusting member 200 and the second adjusting member 300 completely block the second channel 122 and the third channel 123, the first water nozzles 611 and the second water nozzles 621 discharge water synchronously.
[0036] The movement of the first adjusting member 200 and the second adjusting member 300 can be achieved by manually adjusting their positions using a mechanical structure, or by using an electronically controlled structure, such as a servo controller, to control their positions. In one embodiment, as shown... Figure 2 , Figure 4 and Figure 5 As shown, it also includes a linkage 400. The linkage 400 is mounted on the main body 100. The first adjusting member 200 and the second adjusting member 300 are both connected to the linkage 400. The linkage 400 can move relative to the main body 100. When the linkage 400 moves, it drives the first adjusting member 200 and the second adjusting member 300 to move synchronously, thereby simultaneously adjusting the interception area of the first adjusting member 200 on the second channel 122 and the interception area of the second adjusting member 300 on the third channel 123.
[0037] Furthermore, the first adjusting member 200 includes a first support portion 210 and a first insertion portion 220 connected to each other. The first support portion 210 and the first insertion portion 220 may be integrally formed. The second adjusting member 300 includes a second support portion 310 and a second insertion portion 320 connected to each other. The second support portion 310 and the second insertion portion 320 may be integrally formed. Both the first insertion portion 220 and the second insertion portion 320 may be configured as cylindrical structures. The first insertion portion 220 is movably inserted along a first direction into the second channel 122, thereby intercepting the second channel 122. The second insertion portion 320 is movably inserted along the first direction into the third channel 123, thereby intercepting the third channel 123. Both the first support portion 210 and the second support portion 310 are provided with inclined extending first guide grooves 501. The first support portion 210 and the second support portion 310 are located outside the main body 100. The linkage 400 passes through the first guide groove 501 on the first support portion 210 and the first guide groove 501 on the second support portion 310. The linkage 400 slides relative to the main body 100 along a second direction. The first and second directions are perpendicular to each other, and the extension directions of the first guide grooves 501 are inclined to both the first and second directions. Figure 2 and Figure 4 The directions are indicated as follows: the first direction is up and down, and the second direction is left and right. The first guide groove 501 is inclined from the upper left to the lower right. When the linkage 400 moves from left to right, the part of the linkage 400 that passes through the first guide groove 501 slides from the upper left end to the lower right end of the first guide groove 501, causing the first insertion part 220 and the second insertion part 320 to move from bottom to top. That is, it causes the first adjusting part 200 to move from the second position to the first position and simultaneously causes the second adjusting part 300 to move from the fourth position to the third position. Conversely, when the linkage 400 moves from right to left, it causes the first adjusting part 200 to move from the first position to the second position and simultaneously causes the second adjusting part 300 to move from the third position to the fourth position, thereby achieving synchronous movement of the first adjusting part 200 and the second adjusting part 300.
[0038] Based on the above embodiments, such as Figure 4 , Figure 5 and Figure 6As shown, the main body 100 is provided with two spaced-apart guide seats 130. In the direction shown, the two guide seats 130 extend downwards in a frame shape from the lower side of the main body 100. Each guide seat 130 has a guide cavity 131. The guide cavity 131 extends vertically along a first direction. There is a certain gap between the two guide seats 130. A second guide groove 132 is formed on the side wall of the guide cavity 131, extending horizontally in a second direction. A first support part 210 is installed in one of the guide cavities 131, and a second support part 310 is installed in the other guide cavity 131. The first support part 210 and the second support part 310 slide vertically up and down relative to their respective guide cavities 131 in the first direction. The linkage 400 includes a pushing part 410, a connecting rod part 420, and a guide rod part 430 connected in sequence. The pushing part 410 overlaps the lower side of the guide seat 130 and can move horizontally along the guide seat 130. The connecting rod portion 420 extends upward from the upper side of the pushing portion 410 and passes through the gap between the two guide seats 130. The guide rod portion 430 is connected to the upper end of the connecting rod portion 420 and passes through the first guide groove 501 and the second guide groove 132 on both sides in the front-back direction. By driving the pushing portion 410 to move, the connecting rod portion 420 and the guide rod portion 430 are moved in the front-back direction, and the first adjusting member 200 and the second adjusting member 300 are moved up and down in the first direction through the first guide groove 501.
