Description

Technical Field

[0001] This utility model relates to the field of pool cleaning, and in particular to a variable-direction structure for a spray-type pool cleaner. Background Technology

[0002] Over time, water tanks accumulate dirt and grime, requiring regular cleaning. Currently, many users employ sink cleaners to remove this buildup. These cleaners move through the tank, scrubbing and collecting the dirt. One type of sink cleaner uses a water jet to propel itself; this is called a spray-type sink cleaner. However, existing spray-type sink cleaners primarily rely on the fluctuations in the water flow to change direction. This means they cannot actively change direction within the tank, affecting their cleaning effectiveness.

[0003] In view of the above problems, it is necessary to study a reversible structure for a water spray cleaner, which can enable the water spray cleaner to change direction and improve the cleaning effect on the pool. Utility Model Content

[0004] The purpose of this utility model is to provide a reversible structure for a water spray pool cleaner, which enables the water spray pool cleaner to change direction while moving, thereby improving the cleaning effect on the pool.

[0005] To achieve the above objectives, the solution of this utility model is: A reversing structure for a water jet pool cleaner, the water jet pool cleaner having at least one spray channel and a water jet drive device for supplying water flow to the spray channel; at least one spray channel of the water jet pool cleaner is equipped with a reversing mechanism, the reversing mechanism including a swaying reversing rudder blade disposed in the spray channel, and a reversing drive device for driving the swaying reversing rudder blade to sway, the reversing rudder blade being adjacent to the outlet of the spray channel and the swaying center axis of the reversing rudder blade being perpendicular to the forward direction of the water jet pool cleaner.

[0006] The water jet cleaner has two spray channels arranged opposite each other, and each spray channel is equipped with a one-way valve that allows water to flow out in one direction. The water jet drive device supplies water to the two spray channels alternately. The direction-changing mechanism is driven by the one-way valve of the spray channel.

[0007] The water spray type pool cleaner has a water inlet chamber, and the water outlet of the water inlet chamber is connected to the inlet of two spray channels; the water spray drive device includes a water spray impeller that is rotatably installed in the water inlet chamber, and an impeller drive device that drives the water spray impeller to perform forward and reverse rotation at regular intervals.

[0008] The outlet of the water inlet chamber is located on the side of the water inlet chamber, and the inlet of the water inlet chamber is located on one end face of the water inlet chamber; the blades of the water spray impeller are straight blades, and the blades of the water spray impeller face the side of the water inlet chamber.

[0009] The impeller drive device uses an electric motor.

[0010] The impeller drive device is housed in a waterproof housing. The impeller drive device has a connecting shaft extending out of the waterproof housing. The connecting shaft is connected to the water spray impeller and is sealed to the waterproof housing.

[0011] One end of the outlet one-way valve plate has a rotating shaft that is rotatably connected to the jet channel. The outlet one-way valve plate moves against a stop portion provided on the inner wall of the jet channel on the side facing the inlet of the jet channel. The direction-changing mechanism's direction-changing drive device includes a cam reciprocating mechanism and a one-way transmission mechanism. The cam reciprocating mechanism is connected to the direction-changing rudder and is used to drive the direction-changing rudder to oscillate intermittently. The one-way transmission mechanism is in transmission cooperation with the outlet one-way valve plate and the cam reciprocating mechanism, respectively. The one-way transmission mechanism enables the rotating shaft of the outlet one-way valve plate to be in one-way transmission cooperation with the cam reciprocating mechanism.

[0012] The cam reciprocating mechanism includes a cam and a follower. The cam is rotatably mounted on the water jet cleaner, and an inclined cam groove is provided on the side wall of the cam. The follower is connected to the directional rudder and the two rotate synchronously. The side wall of the follower is provided with a guide block that moves in conjunction with the cam groove. The one-way transmission mechanism includes a first ratchet and a first one-way engagement member with multiple first pawls. The first ratchet is rotatably mounted on the water jet cleaner and engages with the cam transmission. The first ratchet has a first internal gear ring. The first one-way engagement member is connected to the rotating shaft of the water outlet one-way valve plate and the two rotate synchronously. Each first pawl of the first one-way engagement member engages one-way with the first internal gear ring of the first ratchet.

[0013] The one-way transmission mechanism further includes a second ratchet and a second one-way engaging member with multiple second pawls. The first ratchet engages with the cam in a one-way transmission manner through the second ratchet and the second one-way engaging member. The second ratchet has a second internal gear ring and a second external gear ring. The first ratchet has a first external gear ring that meshes with the second external gear ring. The second ratchet is connected to the cam. Each second pawl of the second one-way engaging member engages in a one-way manner with the second internal gear ring of the second ratchet. The second one-way engaging member is fixedly fitted to the water spray type pool cleaner.

[0014] The water spray type pool cleaner has multiple wheels, at least one of which is a swivel wheel.

[0015] By adopting the above solution, this utility model uses a directional drive device to drive the directional rudder to swing and change the orientation of the directional rudder. The change in the orientation of the directional rudder can change the water outlet orientation of the spray channel, thereby enabling the water jet cleaner to turn. Attached Figure Description

[0027] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0028] like Figures 1 to 10 As shown, this utility model discloses a reversing structure for a water jet type pool cleaner A. The water jet type pool cleaner A has at least one spray channel 1 and a water jet drive device 2 for supplying water flow to the spray channel 1. The at least one spray channel 1 of the water jet type pool cleaner A is equipped with a reversing mechanism 3. The reversing mechanism 3 includes a reversing rudder 31 that can swing in the spray channel 1 and a reversing drive device 32 that drives the reversing rudder 31 to swing. The reversing rudder 31 is adjacent to the outlet 102 of the spray channel 1 and the swing center axis of the reversing rudder 31 is perpendicular to the forward direction of the water jet type pool cleaner A.

[0029] This utility model uses a directional drive device 32 to drive the directional rudder 31 to swing and change the orientation of the directional rudder 31. The change in the orientation of the directional rudder 31 can change the water outlet direction of the spray channel 1, thereby causing the water jet cleaner A to turn.

[0030] In an embodiment of this utility model, the water-spraying pool cleaner A may have two spray channels 1, which are arranged opposite to each other; the water-spraying drive device 2 supplies water to the two spray channels 1 in turn, so that the water-spraying pool cleaner A moves forward and backward at regular intervals; each spray channel 1 is equipped with a one-way valve 11 that allows water to flow out of the spray channel 1 in one direction, so that when water flows out of one of the two spray channels 1, the other spray channel 1 is closed, preventing the water in the pool from entering through the spray channel 1 and causing dirt mixed in with the water in the pool to affect the operation of the water-spraying drive device 2. Specifically, one end of the outlet one-way valve plate 11 is rotatably connected to the jet channel 1 (this end of the outlet one-way valve plate 11 is provided with a rotating shaft 111 rotatably connected to the jet channel 1), and the side of the outlet one-way valve plate 11 facing the inlet 101 of the jet channel 1 moves against the stop part 12 provided on the inner wall of the jet channel 1; when a certain jet channel 1 is discharging water, the outlet one-way valve plate 11 in the jet channel 1 rotates towards the outlet 102 of the jet channel 1 to open the jet channel 1; and when a certain jet channel 1 is not discharging water, the outlet one-way valve plate 11 in the jet channel 1 resets to close the jet channel 1.

[0031] In an embodiment of this utility model, the water-spraying pool cleaner A has a water inlet chamber 4, and the water outlet 42 of the water inlet chamber 4 is connected to the inlet 101 of the two spray channels 1. The water spraying drive device 2 includes a water spray impeller 21 rotatably disposed in the water inlet chamber 4, and an impeller drive device 22 that drives the water spray impeller 21 to rotate in the forward and reverse directions at regular intervals. When the water spray impeller 21 rotates forward, the water spray impeller 21 delivers the water in the water inlet chamber 4 to one of the two spray channels 1. When the water spray impeller 21 rotates in the reverse direction, the water spray impeller 21 delivers the water in the water inlet chamber 4 to the other spray channel 1.

[0032] In an embodiment of this utility model, the outlet 42 of the water inlet chamber 4 is located on the side of the water inlet chamber 4, and the inlet 41 of the water inlet chamber 4 is located on one end face of the water inlet chamber 4; the blades of the water spray impeller 21 are straight blades, and the blades of the water spray impeller 21 face the side of the water inlet chamber 4; this arrangement allows the water spray impeller 21 to transport the water flow in the water inlet chamber 4 to one of the two spray channels 1 when rotating forward, and to transport the water flow in the water inlet chamber 4 to the other spray channel 1 when rotating in reverse.

[0033] In an embodiment of this utility model, the impeller drive device 22 may be an electric motor; the impeller drive device 22 is housed in a waterproof housing 5, which provides waterproof protection for the impeller drive device 22. The impeller drive device 22 has a connecting shaft 221 extending out of the waterproof housing 5. The connecting shaft 221 is connected to the water spray impeller 21. The connecting shaft 221 and the waterproof housing 5 are sealed together to prevent the waterproof housing 5 from being damaged. The waterproof housing 5 may contain a control circuit board 6 and a battery 7 that are electrically connected to the impeller drive device 22. The battery 7 supplies power to the impeller drive device 22 and the control circuit board 6. The control circuit board 6 controls the impeller drive device 22 to rotate forward and backward at regular intervals.

[0034] In an embodiment of this utility model, the reversing drive device 32 of the reversing mechanism 3 is in transmission cooperation with the water outlet one-way valve plate 11 that cooperates with the spray channel 1 of the reversing mechanism 3, so that when the water outlet one-way valve plate 11 rotates to open the spray channel 1 (when water is discharged from the spray channel 1), the water outlet one-way valve plate 11 drives the reversing rudder 31 to swing once through the reversing drive device 32. Specifically, the directional change mechanism 3's directional change drive device 32 may include a cam reciprocating mechanism 3201 and a one-way transmission mechanism 3202. The cam reciprocating mechanism 3201 is connected to the directional change rudder 31 and is used to drive the directional change rudder 31 to oscillate intermittently. The one-way transmission mechanism 3202 is respectively connected to the outlet one-way valve plate 11 and the cam reciprocating mechanism 3201. The one-way transmission mechanism 3202 enables the outlet one-way valve plate 11 to be connected to the cam reciprocating mechanism 3201 in a one-way transmission, so that when the outlet one-way valve plate 11 rotates to open the spray channel 1, the directional change drive device 32 drives the directional change rudder 31 to oscillate once. It should be noted that this utility model is not limited to providing power to the directional change drive device 32 through the outlet one-way valve plate 11. The directional change drive device 32 may also directly use a motor to drive the directional change rudder 31 to oscillate.

[0035] In an embodiment of this utility model, the cam reciprocating mechanism 3201 may include a cam 321 and a follower 322. The cam 321 is rotatably mounted on the water spray type pool cleaner A. The side wall of the cam 321 is provided with an inclined cam groove 3211. The follower 322 is connected to the directional rudder 31 and the two rotate synchronously. The side wall of the follower 322 is provided with a guide block 3221 that is movably engaged with the cam groove 3211. When the cam 321 rotates intermittently, the guide block 3221 of the follower 322 will move intermittently in the cam groove 3211, causing the follower 322 to oscillate intermittently, thereby driving the directional rudder 31 to oscillate intermittently. The one-way transmission mechanism 3202 may include a first ratchet 323 and a first one-way engagement member 324 having multiple first pawls 3241. The first ratchet 323 is rotatably disposed in the water spray type pool cleaner A and is driven and engaged with the cam 321. The first ratchet 323 has a first internal gear ring 3231. The first one-way engagement member 324 is connected to the rotating shaft 111 of the water outlet one-way valve plate 11 and the two rotate synchronously. Each of the first pawls 3241 of the first one-way engagement member 324 engages one-way with the first internal gear ring 3231 of the first ratchet 323 to achieve one-way transmission and engagement, so that when the water outlet one-way valve plate 11 rotates to open the spray channel 1, the directional drive device 32 drives the directional rudder 31 to swing once. Furthermore, the one-way transmission mechanism 3202 may also include a second ratchet 325 and a second one-way engaging member 326 having multiple second pawls 3261. The first ratchet 323 engages with the cam 321 in a one-way transmission manner through the second ratchet 325 and the second one-way engaging member 326. The second ratchet 325 has a second internal gear ring 3251 and a second external gear ring 3252. The first ratchet 323 has a first external gear ring 3232 that meshes with the second external gear ring 3252. The second ratchet 325 is connected to the cam 321. Each of the second one-way engaging members 326... The second pawl 3261 engages unidirectionally with the second internal gear ring 3251 of the second ratchet 325 to achieve unidirectional transmission. The second unidirectional engagement member 326 is fixedly engaged with the water spray type pool cleaner A. The added second ratchet 325 and second unidirectional engagement member 326 can make the water outlet one-way valve plate 11 return to its original position smoothly. The first ratchet 323, the first unidirectional engagement member 324, the second ratchet 325, and the second unidirectional engagement member 326 can be installed on a mounting base 327, which is then fixedly installed on the water spray type pool cleaner A.

[0036] In an embodiment of this utility model, the water spray type pool cleaner A may be provided with a filter chamber A1 and a suction port A2 communicating with the filter chamber A1. The filter chamber A1 is provided with a filter device 8, which includes a filter seat 81 and a filter screen 82 that cooperates with the filter seat 81. The filter device 8 divides the filter chamber A1 into a communicating sewage chamber A11 and a clean water chamber A12. The sewage chamber A11 is communicating with the suction port A2. The spray channel 1, the water inlet chamber 4, the water spray drive device 2, and the direction changing mechanism 3 are arranged in the clean water chamber A12. When the water spray impeller 21 rotates forward or backward, the water flow in the pool will carry dirt into the sewage chamber A11 from the suction port A2. After that, the dirt is intercepted by the filter device 8 in the sewage chamber A11, and the filtered water flow enters the water inlet chamber 4 through the clean water chamber A12. In this way, the water spray drive device 2 and the direction changing mechanism 3 arranged in the clean water chamber A12 can be free from the interference of dirt.

[0037] In an embodiment of this utility model, the water spray pool cleaner A has multiple wheels 9, at least one of which is a swivel wheel 91, which facilitates smooth movement and direction changes for the water spray pool cleaner A. Specifically, the water spray pool cleaner A may have four wheels 9, which are respectively installed at the four corners of the water spray pool cleaner A. Two adjacent wheels 9 are swivel wheels 91, and the remaining two adjacent wheels 9 are directional wheels 92, so that the water spray pool cleaner A can move smoothly and change direction easily.

[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
