The first battery casing 5-1 and the second battery casing 5-2 are sealed together by a sealing ring. The first battery casing 5-1 and the second battery casing 5-2 can be fixed together by screws, or by snap-fit ​​connections. For ease of installation, the front ends of the first battery casing 5-1 and the front ends of the second battery casing 5-2 are fitted over the drive motor 3. Sealing rings are also used to seal the connection between the front ends of the first battery casing 5-1 and the drive motor 3, and between the front ends of the second battery casing 5-2 and the drive motor 3.

[0046] The front end of the outer casing 1 is provided with an external water inlet 6 opposite to the water-absorbing fan blade 4.

[0047] The outer shell 1 is also provided with a bowl-shaped water spray head 7.

[0048] The outer casing 1 is also provided with a water passage 8 for guiding water drawn in from the outer water inlet 6 to the spray head 7.

[0049] The outer casing 1 includes a front casing 9 and a rear casing 10, which are rotatable relative to each other.

[0050] The water channel 8 includes a water guide shell 11 wrapped around the water suction fan blade 4 and a water guide channel 12 extending downward from the water guide shell 11. The front end of the water guide shell 11 has an inner water inlet 13 facing the outer water inlet 6, and the rear end of the water guide shell 11 is fitted onto the drive motor 3.

[0051] The lower part of the water guiding channel 12 is adapted to the water spray head 7, and the water spray head 7 is sleeved on the lower part of the water guiding channel 12. The lower end of the water spray head 7 has a spray nozzle 17. "The lower part of the water guiding channel is adapted to the water spray head" means that the shape of the lower part of the water guiding channel 12 is adapted to the shape of the inner side of the water spray head 7, so that the water spray head 7 can swing freely.

[0052] The lower end face of the front housing 9 has an opening 15 that is adapted to the spray head 7. The spray head 7 is inserted into the opening 15 and the spray nozzle 14 is exposed. The opening is adapted to the spray head, which means that the shape of the opening 15 is adapted to the shape of the outer side of the spray head 7, so that the spray head 7 can swing freely.

[0053] When this utility model is in operation, as in the prior art, the drive motor 3 works to drive the water suction fan blade 4 to rotate, thereby drawing water from the outside into the outer casing through the outer water inlet 6, and further into the water channel 8 through the inner water inlet 13, and finally spraying it out from the spray nozzle 14 of the spray head 7 under the guidance of the water channel 8.

[0054] Unlike existing technologies, the spa machine of this invention can adjust the water flow from the nozzles in multiple directions: on the one hand, as in existing technologies, since the nozzle 7 is bowl-shaped, it can swing freely to adjust the direction of the water spray; on the other hand, since the front housing 9 and the rear housing 10 can rotate relative to each other, and the water guide shell 11 of the water channel is driven by the motor 3 at the rear end, the front housing 9 can rotate and the water channel 8 can rotate. When the front housing 9 rotates, it can drive the water channel 8 and the nozzle 7 to rotate synchronously, thereby achieving adjustment of the water spray direction in another direction.

[0055] In one embodiment, a suction cup 16 may be provided on the outer casing 1, so that the user can use the suction cup 16 to attach the spa machine to an external environment such as a bathtub.

[0056] In one embodiment, a sealing ring 17 is provided on the outer side of the lower end of the water guiding channel 12, and the sealing ring 17 abuts against the inner sidewall of the spray head 7. The presence of the sealing ring 17 has two functions: firstly, the water drawn in is sealed by the sealing ring 17, so it will not leak out from between the water guiding channel 12 and the spray head 7, and almost all of it will be sprayed out from the spray nozzle 14 of the spray head 7, ensuring the intensity of the hydrotherapy water flow; secondly, due to the presence of the sealing ring 17, the spray head 7 has a damping feel when it needs to swing to adjust the spray angle, making operation more comfortable.

[0057] In one embodiment, for ease of assembly, the water guiding channel 12 is divided into two sections: the upper water guiding channel 12-1 of the upper section is connected to the water guiding shell 11, and in a preferred embodiment, the upper water guiding channel 12-1 and the water guiding shell 11 are integrally formed; the lower water guiding channel 12-2 of the lower section is tightly fitted onto the upper water guiding channel 12-1, and the lower part of the lower water guiding channel 12-2 is formed into a shape that is adapted to the water spray head. When a sealing ring 17 is provided, the sealing ring 17 is located on the outer side of the lower end of the lower water guiding channel 12-2.

[0058] In one embodiment, the front housing 9 and the rear housing 10 are rotatable relative to each other by having a concave ring 18 at the tail end of the front housing 9 and a convex ring 19 at the head end of the rear housing 10, with the convex ring 19 fitting within the concave ring 18. Alternatively, the front housing may have a convex ring at the tail end and a concave ring at the head end of the rear housing, with the convex ring fitting within the concave ring.

[0059] In one embodiment, for ease of assembly, the front housing 9 includes a first front side shell 9-1, a second front side shell 9-2, and a third bottom shell 9-3. The first front side shell 9-1 and the second front side shell 9-2 are mated together, and the third bottom shell 9-3 is connected to the lower ends of the first front side shell 9-1 and the second front side shell 9-2. Specifically, the connection method can be as follows: the first front side shell 9-1 and the second front side shell 9-2 are snap-fitted together, and the third bottom shell 9-3 is snap-fitted together with both the first front side shell 9-1 and the second front side shell 9-2. For example, a front latch can be provided on the first front side shell 9-1, with a front latch opening on the front latch; a front latch block can be provided on the second front side shell 9-2, with the front latch block engaging in the front latch opening; a front latch hook can be provided on the third bottom shell 9-3; and a front latch edge can be provided on the first front side shell 9-1 and the second front side shell 9-2, with the front latch hook fastened to the front latch edge.

[0060] In one embodiment, the inner side of the first front shell 9-1 and the inner side of the second front shell 9-2 are both provided with forward protruding ribs. After assembly, the forward protruding ribs abut against the drive motor 3, making the first front shell 9-1 and the second front shell 9-2 more stable after assembly.

[0061] In one embodiment, for ease of assembly, the rear housing 10 includes a first rear side shell 10-1, a second rear side shell 10-2, and a third tail cover 10-3. The first rear side shell 10-1 and the second rear side shell 10-2 are mated together, and the third tail cover 10-3 is connected to the rear ends of the first rear side shell 10-1 and the second rear side shell 10-3. Specifically, the connection method can be as follows: the first rear side shell 10-1 and the second rear side shell 10-2 are snap-fitted together, and the third tail cover 10-3 is snap-fitted together with both the first rear side shell 10-1 and the second rear side shell 10-2. For example, a rear latch can be provided on the first rear side shell 10-1, with a rear latching opening on the rear latch; a rear latching block can be provided on the second rear side shell 10-2, with the rear latching block engaging in the rear latching opening; a rear latching hook can be provided on the third tail cover 10-3; and a rear latching edge can be provided on the first rear side shell 10-1 and the second rear and rear shells 10-2, with the rear latching hook fastened to the rear latching edge.

[0062] In one embodiment, the inner side of the first rear shell 10-1 and the inner side of the second rear shell 10-2 are both provided with rear ribs. After assembly, the rear ribs abut against the battery shell 5, making the first rear shell 10-1 and the second rear shell 10-2 more stable after assembly.

[0063] In one embodiment, a hanging ring 20 may be provided on the third tail cap 10-3 to facilitate the storage of the spa machine.

[0064] In one embodiment, the rear housing 10 has a raised boss 21 at its tail (on the third tail cover 10-3 in the figure). The boss 21 has an air pipe connector 22 extending into the rear housing 10. The surface of the boss 21 has an arc-shaped ventilation groove 23. The air pipe connector 22 communicates with the ventilation groove 23. An air pipe is fitted onto the air pipe connector 22, and the air pipe extends into the front housing 9. A knob 24 is fitted over the boss 21. The inner end face of the knob 24 has an inwardly protruding part 25, which abuts against the end face of the boss 21. The end face of the knob 24 has a ventilation hole 26 penetrating through the end face, and the end of the ventilation hole 26 penetrates the protruding part 25. When the knob 24 is rotated, the ventilation hole 26 can be aligned with the ventilation groove 23. The significance of this mechanism is that, due to the water-absorbing effect of the front suction fan blades 4, the interior of the outer casing 1 is relatively under low pressure. At this time, outside air can enter through the vent hole 26 on the knob 24. When the knob 24 is rotated so that its vent hole 26 aligns with the vent groove 23, outside air can enter the air pipe connector 22 through the vent groove 23 and be transmitted to the front casing 9 via the air pipe to generate bubbles, achieving a surfing effect. When the knob 24 is rotated so that its vent hole 26 is not aligned with the vent groove 23, the vent hole 26 is blocked, and no air is emitted. The air pipe preferably extends to the vicinity of the outer water inlet 6 of the front casing 9 to facilitate bubbling. In one embodiment, a clip 27 is provided on the water guide shell 11, and the air pipe can be clipped onto the clip 27 for secure fixation.

[0065] In one embodiment, the boss 25 has a central groove 28, and the knob 24 has a central pivot 29, which passes through the central groove 28 to facilitate the installation and rotation of the knob 24.

[0066] In one embodiment, the width of the ventilation groove 23 gradually increases from the head to the tail. The air pipe connector 22 communicates with the ventilation groove 23 at the tail or at the head. In this case, the air output can be adjusted by adjusting the relative position of the ventilation hole 26 and the ventilation groove 23: when the ventilation hole 26 corresponds to the narrower part of the ventilation groove 23, the air output is smaller; when the ventilation hole 26 corresponds to the wider part of the ventilation groove 23, the air output is larger.
