[0016] The water outlet direction of the lowermost said notch is set upward, and the intersection position between the straight line of the water outlet direction of the lowermost said notch and the straight line of the water outlet direction of the uppermost said notch is higher than the first wave peak height of the wave plate close to the piston chamber.

[0017] Further, the number of said notches is more than three;

[0018] The water outlet direction of the said notches other than the uppermost said notch and the lowermost said notch is set horizontally.

For a person of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] The present application discloses a wave maker.

[0041] Please refer to Figure 1 and Figure 5 An embodiment of the wave maker provided in the present application includes:

[0042] The wave chamber 200, the piston chamber 100, the piston piece 1, the blocking piece 2 and the driving assembly 300.

[0043] The piston chamber 100 is in communication with the wave chamber 200 through a plurality of notches 101 arranged from top to bottom.

[0044] The piston chamber 100 is provided with an opening for the piston piece 1 to extend into, and the wave chamber 200 is provided with a wave plate 3. As shown in Figure 5 In the present application, a plurality of wave crests with gradually decreasing height in the direction away from the notch 101 are arranged on the wave plate 3.

[0045] The driving assembly 300 is connected with the piston piece 1 and the blocking piece 2, and is used to drive the piston piece 1 and the blocking piece 2 to reciprocate together.

[0046] The piston piece 1 moves to press the water in the piston chamber 100 out of the notch 101, and the blocking piece 2 blocks the notch 101 through which the piston piece 1 passes one by one. The blocking piece 2 arranged can be used to block the notch 101, so as to prevent the water from overflowing into the notch 101 above the piston piece 1 when the piston piece 1 is pressed to the bottom, so that the piston piece 1 is not subjected to excessive pressure when it rises, thereby affecting the service life and use stability of the driving assembly 300.

[0047] The wave maker designed in the present application can make the water in the wave chamber 200 naturally overflow into the piston chamber 100 through the notch 101 when the driving assembly 300 drives the piston piece 1 and the blocking piece 2 to rise to a certain height to expose the notch 101, and can press the water in the piston chamber 100 and form a jet through the notch 101 when the driving assembly 300 drives the piston piece 1 and the blocking piece 2 to move downward, so that the water sprayed out of the process will form wave after wave. The design is simple and compact, and the driving system is simple, which only needs a driving assembly 300 to reciprocatingly drive the piston piece 1 to move, thereby continuously spraying water flow, so that the wave has good persistence.

[0048] The above is the first embodiment of the wave maker provided by the embodiment of the present application, and the second embodiment of the wave maker provided by the embodiment of the present application is as follows, please refer to Figures 1 to 6 .

[0049] Based on the scheme of the above first embodiment:

[0050] Further, as shown in Figure 1 , Figure 2 and Figure 4 , as for the arrangement of the piston chamber 100, it can be attached to one end position in the wave chamber 200.

[0051] Correspondingly, a plurality of notches 101 are arranged on the side wall of the piston chamber 100 away from the one end position in the wave chamber 200, and the wave plate 3 is arranged in the wave chamber 200 and located on one side of the piston chamber 100.

[0052] Further, as shown in Figure 4 , in order to limit the movement of the blocking piece 2 so that the blocking piece 2 can better block the notch 101, a slot is arranged in the piston chamber 100 for the blocking piece 2 to move in, and the movement of the blocking piece 2 is limited by the slot, so that the blocking piece 2 can only realize the lifting movement, and the movement in the horizontal direction is limited by the slot, thereby avoiding the situation that the notch 101 is opened by the impact of the water flow. Of course, other limiting methods can also be used, for example, two guide rail slots are arranged outside the side wall, and the blocking piece 2 is inserted into the guide rail slots, and the limiting can also be realized by the guide rail slots, which is not limited in particular.

[0053] The shape of the piston chamber 100 and the wave chamber 200 in the present application is not limited, which can be rectangular, that is, the piston chamber 100 and the wave chamber 200 can be cubic structures, the piston chamber 100 and the wave chamber 200 can be two independent container structures, of course, a large container structure can also be provided, and a partition plate can be arranged in the large container structure to separate the piston chamber 100 and the wave chamber 200, and the specific design is not limited.

[0054] Further, as shown in Figure 4 , the plurality of notches 101 gradually decrease from top to bottom. Different sizes of water flows can be obtained from several notches 101, thereby forming different waves. The water outlet ends of the notches 101 gradually decrease from top to bottom (for example, if the water outlet end is a square port, the width of the water outlet end gradually decreases from top to bottom), and this design can form a relatively stable reaction force on the bottom of the piston 1. When the piston 1 is just pressed, there is a large amount of water in the piston chamber 100, at this time, the notches 101 are not blocked by the blocking piece 2, so the water in the piston chamber 100 can be easily pressed out, as the piston 1 slowly descends, the water flow in the piston chamber 100 decreases, and at the same time, the notches 101 also decrease, so that the reaction force on the piston 1 does not change dramatically.

[0055] Further, as shown in Figure 1 and Figure 4 , the water outlet direction of the uppermost notch 101 is arranged downward, the water outlet direction of the lowermost notch 101 is arranged upward, and the intersection position between the straight line of the water outlet direction of the uppermost notch 101 and the straight line of the water outlet direction of the lowermost notch 101 is higher than the first wave peak height of the wave plate 3 close to the piston chamber 100. This design can not only reduce the energy consumption of the jet flow of the lowermost notch 101 when it hits the wave plate 3, but also can make the jet flow of the uppermost notch 101 more fully contact the wave plate 3, thereby better forming waves.

[0056] Further, taking the design of more than three notches 101 as an example, the water outlet direction of the notches 101 except the uppermost notch 101 and the lowermost notch 101 can be arranged horizontally. The middle notch 101 is arranged horizontally, so that the jet flow from the middle notch 101 directly passes over the wave plate, which can reduce the jet flow resistance. Taking the design of three notches as an example, the two jet flows of the upper notch 101 and the lower notch 101 intersect with the jet flow of the middle notch 101 to a certain extent, and both pass over the first wave peak of the wave plate 3. It can be understood that the intersection position of the three jet flows is higher than the first wave peak height of the wave plate 3.

[0057] Further, as shown in Figure 1As shown, in a specific implementation of preventing water from flowing into the piston 1, the bottom height of the baffle 2 is designed to be between the bottom height of the piston 1 and the top height of the piston 1. Therefore, when water is squeezed out, the water will first go out from the slot 101, and then the slot 101, which cannot be squeezed out, is blocked by the baffle.

[0058] Furthermore, such as Figure 3 As shown, the drive assembly 300 includes a push rod 4, a first connecting rod 51, and a rotary motor 6.

[0059] Push rod 4 extends into piston chamber 100 and is fixedly connected to piston component 1. Push rod 4 is provided with support rod 41 fixedly connected to stop component 2, so that piston component 1 and stop component 2 can move together.

[0060] The output shaft of the rotary motor 6 is connected to the first connecting rod 51, driving the first connecting rod 51 to rotate. The first connecting rod 51 is rotatably connected to the push rod 4. The rotary motor 6 drives the first connecting rod 51 to rotate, which in turn drives the piston 1 and the stop 2 to reciprocate up and down. The rotary motor 6 can rotate in only one direction to achieve reciprocating up and down motion, meaning that only one motor is needed to generate waves in this design. Moreover, since the rotational speed of the rotary motor 6 is adjustable, the wave speed it generates also has a large adjustable range; the higher the rotational speed of the rotary motor 6, the higher the frequency of the generated waves.

[0061] The first connecting rod 51 can also be replaced by a cam, and there are no specific restrictions.

[0062] Furthermore, such as Figure 6 As shown, the first connecting rod 51 has multiple spaced connecting holes 511 that can be rotatably connected to the push rod 4. Thus, by connecting the push rod 4 with different connecting holes 511, the push rod 4 can have different strokes. It can be understood that the connecting holes 511 on the first connecting rod 51 are used to adjust the different strokes of the push rod 4. The higher the connecting hole 511 is selected, the greater the stroke of the push rod 4, the more water is sprayed, and the higher the wave height is generated. The adjustable stroke design also makes the wave generator more versatile. This stroke adjustment uses a recessed design, but it is not limited to this; other limiting methods can also be used to make the push rod 4's stroke adjustable. No specific limitation is imposed.

[0063] Furthermore, such as Figure 3 As shown, to facilitate the connection of the push rod 4, the drive assembly 300 also includes a second connecting rod 52; one end of the second connecting rod 52 is rotatably connected to the first connecting rod 51, and the other end is rotatably connected to the push rod 4. The second connecting rod 52 and the first connecting rod 51 can be rotatably connected by a pin 7, and the second connecting rod 52 and the push rod 4 can also be connected by a pin 7.

[0064] In this application, the second connecting rod 52 is longer than the first connecting rod 51, forming a long rod, while the first connecting rod 51 forms a short rod. In this application, there can be two of both the first connecting rod 51 and the second connecting rod 52, forming two sets of linkage mechanisms. There are also two corresponding rotary motors 6. Of course, one rotary motor 6 can also be used to synchronously drive the two sets of first connecting rods 51 and second connecting rods 52. Those skilled in the art can make appropriate changes based on this, without limitation.

[0065] The wave generator provided in this application has been described in detail above. For those skilled in the art, there may be changes in the specific implementation and application scope based on the ideas of the embodiments of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
