[0053] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] like Figures 1 to 7 As shown in the figure, a spray mechanism includes: a spray arm seat 200 and a spray arm 100; one end of the spray arm 100 is rotatably connected to the spray arm seat 200, and a water flow channel 110 is provided in the spray arm 100, and a first water spray port 111 and a second water spray port 112 connected to the water flow channel 110 are provided on the spray arm 100; the first water spray port 111 drives the spray arm 100 to move in a first direction, and the second water spray port 112 drives the spray arm 100 to move in a second direction, and the first direction and the second direction are opposite directions; a magnetic component is provided in the water flow channel 110, and the magnetic component can generate magnetic force, and the magnetic force changes according to the temperature of the water in the water flow channel 110, when the magnetic force is greater than a first threshold value, the magnetic component closes the first water spray port 111 and opens the second water spray port 112; when the magnetic force is less than the first threshold value, the magnetic component opens the first water spray port 111 and closes the second water spray port 112.

[0055] The spray mechanism provided in this embodiment includes a spray arm 100 and a spray arm base 200. One end of the spray arm 100 is connected to the spray arm base 200 and can rotate on the spray arm base 200 to increase the spray angle and improve the cleaning effect. The liquid in the water flow channel 110 is sprayed out by the first water spray port 111 and the second water spray port 112. When the liquid is sprayed out, it can generate a certain thrust to push the spray arm 100 to rotate on the spray arm base 200, eliminating the need for a motor and other structures, avoiding occupying space in the equipment and saving costs. The spray direction of the first water spray port 111 and the spray direction of the second water spray port 112 are opposite, so that the spray arm 100 can rotate in different directions. For example, when water is sprayed out from the first water spray port 111, it can drive the spray arm 100 to rotate in the first direction; when water is sprayed out from the second water spray port 112, it can drive the spray arm 100 to rotate in the second direction. By changing the rotation direction of the spray arm 100, the spray mechanism can achieve a more comprehensive cleaning angle, thereby achieving a better washing effect. Furthermore, by providing a magnetic component, the first water spray port 111 is opened and the second water spray port 112 is closed, or the first water spray port 111 is closed and the second water spray port 112 is opened, based on the principle that the magnetic force between the magnetic components changes with temperature, thereby changing the rotation direction of the spray arm 100. This eliminates the need for motors, valves, and other equipment, thus saving costs.

[0056] like Figure 6 and Figure 7 As shown, the magnetic component includes a first magnetic part 120 and a second magnetic part 130 that are arranged opposite to each other above and below, and there is magnetic force between the first magnetic part 120 and the second magnetic part 130; the second magnetic part 130 is connected to the inner wall of the water flow channel 110, and the first magnetic part 120 is arranged in the water flow channel 110 and can move in the water flow channel 110.

[0057] In this embodiment, there may be an attractive force or a repulsive force between the first magnetic member 120 and the second magnetic member 130 . The first magnetic member 120 moves in the water flow channel 110 , specifically, along the direction of the magnetic force between the first magnetic member 120 and the second magnetic member 130 .

[0058] In actual use, such as Figure 6 and Figure 7As shown, the inner wall of the water flow channel 110 is provided with a groove, and the second magnetic member 130 is arranged in the groove; at the same time, the first magnetic member 120 and the second magnetic member 130 are arranged up and down, and the first magnetic member 120 moves in the vertical direction in the water flow channel 110; when the magnetic force is greater than the gravity of the first magnetic member 120, the first water spray port 111 is closed and the second water spray port 112 is opened; when the magnetic force is less than the gravity of the first magnetic member 120, the first water spray port 111 is opened and the second water spray port 112 is closed.

[0059] The spray mechanism provided in this embodiment utilizes the combination of magnetic force and gravity. The first magnetic part 120 is arranged in the water flow channel 110 and moves in the vertical direction in the water flow channel 110. There is a magnetic force between the first magnetic part 120 and the second magnetic part 130, wherein the magnetic force is a kind of interaction force, which is the result of the interaction between two magnets and can be expressed as attraction and repulsion. The second magnetic part 130 uses magnetic force to control the first magnetic part 120 to move up and down in the water flow channel 110. When the magnetic force is greater than the gravity of the first magnetic part 120, the first water outlet 111 is closed and the second water outlet 112 is opened; when the magnetic force is less than the gravity of the first magnetic part 120, the first water outlet 111 is opened and the second water outlet 112 is closed.

[0060] like Figures 1 to 7 As shown, the inner wall of the water flow channel 110 is provided with a first through hole 113 and a second through hole 114 arranged up and down, and the first through hole 113 and the second through hole 114 are arranged opposite to each other, the first through hole 113 is connected to the first water spray port 111, and the second through hole 114 is connected to the second water spray port 112; the first magnetic part 120 is arranged between the first through hole 113 and the second through hole 114, and the first magnetic part 120 can move up and down in the water flow channel 110 to close the first through hole 113, open the second through hole 114, or close the second through hole 114 and open the first through hole 113.

[0061] The spray mechanism provided in this embodiment is specifically provided with a first through hole 113 in communication with the first water spray port 111, and a second through hole 114 in communication with the second water spray port 112 in the water flow channel 110. Water in the water flow channel 110 is drawn out through the first through hole 113 and the second through hole 114. At the same time, since the first magnetic member 120 and the second magnetic member 130 utilize magnetic force and gravity, the first through hole 113 and the second through hole 114 are arranged vertically. When the magnetic force between the first magnetic member 120 and the second magnetic member 130 is greater than or equal to the gravity of the first magnetic member 120, one surface of the first magnetic member 120 connects to the outer edge of the first through hole 113, covering the first through hole 113 and closing the first through hole 113. At this time, water flows in from the second through hole 114 and is sprayed out through the second water spray port 112, driving the spray arm 100 to rotate in the second direction. The water temperature in the water flow channel 110 will gradually increase. Under the influence of the water temperature, the magnetic force between the first magnetic part 120 and the second magnetic part 130 will weaken. When the magnetic force is less than the gravity of the first magnetic part 120, one surface of the first magnetic part 120 is connected to the outer edge of the second through hole 114, covering the second through hole 114. At this time, water flows in from the first through hole 113 and is sprayed out through the first water spray port 111, driving the spray arm 100 to rotate in the first direction.

[0062] It is understandable that the axes of the first through hole 113 and the through holes can also be arranged parallel to the axis of the water flow channel 110. The first through hole 113 and the second through hole 114 are blocked by the side surface of the first magnetic member 120.

[0063] In the spray mechanism provided in this embodiment, the configuration of the second magnetic member 130 is determined by the materials of the first magnetic member 120 and the second magnetic member 130 .

[0064] Example 1

[0065] like Figure 4 and Figure 5 As shown, the second magnetic member 130 is disposed at the outer edge of the first through-hole 113. At this point, the force between the first magnetic member 120 and the second magnetic member 130 is an attractive force. The second magnetic member 130 attracts the first magnetic member 120 to the outer edge of the first through-hole 113. The upper surface of the first magnetic member 120 connects to the outer edge of the first through-hole 113, closing the first through-hole 113 and opening the second through-hole 114.

[0066] In this embodiment, when the water temperature in the water flow channel 110 increases, the attraction between the first magnetic member 120 and the second magnetic member 130 gradually decreases. When the attraction between the first magnetic member 120 and the second magnetic member 130 is less than the weight of the first magnetic member 120, the first magnetic member 120 falls, and the lower surface is connected to the outer edge of the second through hole 114. The second through hole 114 is closed, and the first through hole 113 is opened.

[0067] The spray mechanism provided in this embodiment arranges the second magnetic member 130 at the outer edge of the first through hole 113 . At this time, the suction force between the first magnetic member 120 and the second magnetic member 130 is maximum, and the second magnetic member 130 is prevented from occupying too much space in the water flow channel 110 .

[0068] In actual use, the first magnetic member 120 is a cubic structure.

[0069] It is understandable that, in this embodiment, the second magnetic member 130 can be arranged in a variety of forms.

[0070] The second magnetic member 130 may be an annular member and is disposed at the outer edge of the first through hole 113 by welding, gluing, or the like.

[0071] The second magnetic member 130 may also be a block structure, and is disposed at the outer edge of the first through hole 113 by welding, gluing, etc., and is spaced apart at the outer edge of the first through hole 113 .

[0072] A groove for cooperating with the second magnetic member 130 may be further provided at the outer edge of the first through hole 113 , and the second magnetic member 130 may be installed in the installation groove. Alternatively, the second magnetic member 130 may be directly connected to the inner wall of the water flow channel 110 .

[0073] The spray mechanism provided in this embodiment further includes a water tank connected to the water flow channel 110. A heater is provided within the water tank. The heater heats the water within the water tank to increase the water temperature within the water flow channel 110. A booster pump is also provided between the water tank and the water flow channel 110 to increase the pressure of the water when it is sprayed from the first and second water spray ports 111, 112, thereby generating greater thrust.

[0074] In this embodiment, in actual use, the first magnetic member 120 is an iron block, and the second magnetic member 130 is a magnet provided at the outer edge of the first through hole 113 .

[0075] It is understandable that the second magnetic member 130 may be an iron block and the first magnetic member 120 may be a magnet.

[0076] It is also possible that the second magnetic component 130 and the first magnetic component 120 are both magnets, and the different magnetic poles of the first magnetic component 120 and the second magnetic component 130 are arranged relative to each other. For example, when the N pole of the second magnetic component 130 points into the water flow channel 110, the S pole of the first magnetic component 120 is arranged relative to the second magnetic component 130.

[0077] Example 2

[0078] The second magnetic member 130 is disposed at the outer edge of the second through-hole 114. At this point, the force between the first magnetic member 120 and the second magnetic member 130 is a repulsive force. The second magnetic member 130 repels the first magnetic member 120 from the outer edge of the first through-hole 113. The upper surface of the first magnetic member 120 connects to the outer edge of the first through-hole 113, closing the first through-hole 113 and opening the second through-hole 114.

[0079] In this embodiment, when the water temperature in the water flow channel 110 increases, the repulsive force between the first magnetic member 120 and the second magnetic member 130 gradually decreases. When the repulsive force between the first magnetic member 120 and the second magnetic member 130 is less than the weight of the first magnetic member 120, the first magnetic member 120 falls, and the lower surface is connected to the outer edge of the second through hole 114. The second through hole 114 is closed, and the first through hole 113 is opened.

[0080] The structure and installation form of the first magnetic member 120 and the second magnetic member 130 are the same as those in the first embodiment and will not be described again here.

[0081] In this embodiment, the first magnetic member 120 and the second magnetic member 130 are both magnets, and the same magnetic poles of the first magnetic member 120 and the second magnetic member 130 are arranged relative to each other. For example, the second magnetic member 130 points to the inside of the water flow channel 110, and the N pole of the first magnetic member 120 is arranged relative to the second magnetic member 130.

[0082] like Figure 6 and Figure 7 As shown, a limiting assembly is provided in the water flow channel 110; a limiting cavity is provided in the limiting assembly, and the first magnetic component 120 moves in the limiting cavity; the two ends of the limiting cavity are respectively connected to the outer edge of the first through hole 113 and the outer edge of the second through hole 114, and the side wall of the limiting cavity is also connected to the water flow channel 110.

[0083] In the spray mechanism provided in this embodiment, since the first through hole 113 and the second through hole 114 are arranged vertically opposite each other, and the water in the water flow channel 110 has a certain pressure, a limiting assembly is required within the water flow channel 110 to prevent the first magnetic member 120 from being swept away by the water flow when it moves up and down within the water flow channel 110. Furthermore, the sidewalls of the limiting cavity are in communication with the water flow channel 110, allowing the water in the water flow channel 110 to flow through the limiting cavity into the first through hole 113 or the second through hole 114 without affecting the rotation of the spray arm 100.

[0084] like Figure 6 and Figure 7 As shown, specifically, the limiting assembly includes a first limiting rib 115 and a second limiting rib 116 arranged relatively to each other; the two ends of the first limiting rib 115 are respectively connected to the outer edge of the first through hole 113 and the outer edge of the second through hole 114; the two ends of the second limiting rib 116 are respectively connected to the outer edge of the first through hole 113 and the outer edge of the second through hole 114; the first magnetic part 120 is arranged between the first limiting rib 115 and the second limiting rib 116.

[0085] In actual use, the cross-sections of the first limiting rib 115 and the second limiting rib 116 are arc-shaped, and the first magnetic part 120 is between the first limiting rib 115 and the second limiting rib 116, which can prevent the water flow from washing away the first magnetic part 120 and affecting the first magnetic part 120 controlling the opening and closing of the first through hole 113 and the second through hole 114.

[0086] like Figures 1 to 7 As shown, the spray arm 100 includes an upper cover 140 and a lower cover 150 ; the upper cover 140 and the lower cover 150 are respectively provided with oppositely arranged sinking grooves, and the upper cover 140 and the lower cover 150 are connected to form the water flow channel 110 .

[0087] In the spray mechanism provided in this embodiment, the spray arm 100 is formed by welding an upper cover 140 and a lower cover 150 , which facilitates the production and manufacture of the spray arm 100 .

[0088] In this embodiment, the first limiting rib 115 and the second limiting rib 116 can be arranged in a variety of ways.

[0089] The first limiting rib 115 and the second limiting rib 116 can be arranged on the upper cover 140 at the same time, or can be arranged on the lower cover 150 at the same time; or the first limiting rib 115 and the second limiting rib 116 can be arranged in sections, that is, the upper cover 140 and the lower cover 150 are both provided with relatively set limiting protrusions. When the upper cover 140 and the lower cover 150 are connected, the limiting protrusions located on the upper cover 140 and the lower cover 150 are correspondingly connected to form the first limiting rib 115 and the second limiting rib 116.

[0090] like Figure 6 and Figure 7 As shown, in actual use, the first through hole 113 and the first water spray port 111 are located on the upper cover 140 , and the second through hole 114 and the second water spray port 112 are located on the lower cover 150 .

[0091] like Figure 1 As shown, the upper cover 140 is provided with at least one spray hole 141 ; one end of the spray hole 141 is communicated with the water flow channel 110 , and the other end is communicated with the outside.

[0092] The spray mechanism provided in this embodiment has the spray holes 141 for cleaning the dishes in the inner pot. In actual use, the spray arm 100 is provided with multiple spray holes 141 at intervals, and the water outlet direction of each spray hole 141 can be different, so as to clean all the blind spots of the dishes, thereby achieving a better cleaning effect.
