Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a spa massage chair. Background Technology

[0002] With the fast pace of modern life, prolonged periods of working with heads down at desks have become the norm, leading to a gradual increase in the incidence of chronic diseases such as lumbar muscle strain, lumbar disc herniation, and cervical spondylosis. As the demand for massage devices increases, people also have higher expectations for product performance and user experience. Current massage devices generally include roller massage, airbag massage, pulse massage, and hydrotherapy massage. Among these, hydrotherapy massage combines multiple factors such as water flow, temperature, and massage, providing users with a more comfortable and immersive experience. Through the stimulation of temperature and mechanical stimulation in the water, hydrotherapy massage promotes blood and lymphatic flow, making connective tissue easier to stretch, relieving muscle spasms, reducing muscle pain, and promoting relaxation and stress relief.

[0003] For example, Chinese patent application number 202110598518.X discloses a water pressure stimulation acupoint massager, including a main body, a water pump, a water tank, an air pump, a water outlet control valve, a control system, a finger rangefinder, and an acupoint controller. Several shower heads and multi-hole nozzles are distributed on the front side of the main body. The water pump, water tank, and air pump are connected sequentially via pipes. The water tank stores a certain amount of water, and the air pump draws in air, rapidly supplying the pressurized water mixture to the two water outlet control valves. These valves control the water flow rate of each shower head and multi-hole nozzle, achieving a hydrotherapy massage for the back. However, the water flow from the shower heads and multi-hole nozzles directly acts on the back, causing the floor to become slippery after splashing. This limits its use to bathroom applications and only considers massaging the shoulders and back, lacking the function of simultaneously massaging the chest and abdomen. Utility Model Content

[0048] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0049] like Figures 1 to 4 As shown, a preferred embodiment of the present utility model of a spa massage chair includes a seat body 1, a water tank at the bottom of the seat body 1, a massage groove on the side of the seat body 1 near the back of the human body, and a plurality of nozzles installed in the massage groove. The water tank and each nozzle are connected.

[0050] It also includes a drive unit, which is used to supply water from the water tank to each nozzle;

[0051] A waterproof membrane 8 is installed at the front end of each nozzle on the massage tank, and a return channel 9 is provided at the bottom of the massage tank. The water sprayed from each nozzle flows into the return channel 9 after impacting the waterproof membrane 8. The return channel 9 is connected to the water tank. The waterproof membrane 8 blocks the sprayed water flow, and the bulge of the waterproof membrane 8 stimulates the acupoints of the user. The user can enjoy the hydrotherapy massage without touching the water, so there is no need to worry about getting clothes or floors wet. With the return channel 9, water is recycled, which solves the problem of scene limitation caused by water splashing in traditional hydrotherapy massagers. It can be used safely in non-bathroom environments.

[0052] A chest and abdomen massage structure can be detachably connected to the side of the seat body 1 closest to the back of the user. The chest and abdomen massage structure can slide up and down along the seat body 1 and can also slide back and forth along the seat body 1, expanding the coverage of the massage area and realizing the coordinated massage function of the back and chest and abdomen. Users can flexibly adjust the massage position according to their needs, which improves the product's functional diversity and ergonomic adaptability.

[0053] Specifically, the massage groove includes a first massage groove 4 and a second massage groove 5 that are symmetrically arranged on the left and right sides. A waterproof membrane 8 is installed at the front end of both the first massage groove 4 and the second massage groove 5. A vertically extending spinal groove 2 is provided between the first massage groove 4 and the second massage groove 5. A scanning head 3 is slidably installed in the spinal groove 2.

[0054] Specifically, a lead screw and nut structure is installed inside the spinal groove 2. The nut is rigidly connected to the scanning head 3. The drive motor drives the lead screw to rotate, and the nut drives the scanning head 3 to move up and down along the spinal groove 2. When the scanning head 3 moves up and down, it scans from the spinous process of the seventh cervical vertebra to the spinous process of the first thoracic vertebra and the junction of the depression below it, thereby determining the user's spinal position and aligning the spinal position with the spinal groove 2.

[0055] Specifically, the nozzles include multi-hole nozzles 6 and single-hole nozzles 7. The first massage groove 4 is provided with a number of multi-hole nozzles 6 and a number of single-hole nozzles 7, and the second massage groove 5 is provided with a number of multi-hole nozzles 6 and a number of single-hole nozzles 7.

[0056] The first massage tank 4 has several multi-hole nozzles 6 and several single-hole nozzles 7 arranged in groups at intervals, with each group including two multi-hole nozzles 6 and one single-hole nozzle 7.

[0057] The second massage tank 5 has several multi-hole nozzles 6 and several single-hole nozzles 7 arranged in groups at intervals, with each group including two multi-hole nozzles 6 and one single-hole nozzle 7; the multi-hole nozzles 6 form a shower-like water outlet, and the single-hole nozzles 7 form a single water jet outlet, so that different combinations of nozzles can achieve diversified water pressure massage.

[0058] The chest and abdomen massage structure includes a central rod 11, a first telescopic rod 121, a second telescopic rod 122, and a massager 14;

[0059] A guide rail 13 extending along the middle rod 11 is provided on the side of the middle rod 11 facing the seat body 1. Several massagers 14 are detachably connected inside the guide rail 13, and the massage heads 36 of each massager 14 face the human chest and abdomen.

[0060] Specifically, both the first telescopic rod 121 and the second telescopic rod 122 consist of an outer tube and an inner tube, with the inner tube capable of sliding along the axial direction of the outer tube. The outer tube and the inner tube are fixed in relative position by locking bolts; when the locking bolts are loosened, the bolt ends separate from the outer wall of the inner tube, relieving radial pressure, and the inner tube can slide freely within the outer tube to adjust its length; when the locking bolts are tightened, the bolts press against the outer wall of the inner tube through friction, using static friction resistance to restrict the movement of the inner tube.

[0061] The seat body 1 has a first mounting rail 101 and a second mounting rail 102 extending vertically on both sides of its two sides, respectively.

[0062] One end of the first telescopic rod 121 is fixedly connected to the intermediate rod 11, and the other end of the first telescopic rod 121 is slidably installed in the first mounting rail 101.

[0063] One end of the second telescopic rod 122 is fixedly connected to the intermediate rod 11, and the other end of the second telescopic rod 122 is slidably installed in the second mounting rail 102.

[0064] Specifically, such as Figure 5 As shown, the unlocking and positioning system of the telescopic rod adopts a double buckle linkage mechanism. The middle of the first mounting rail 101 and the second mounting rail 102 are both fixed with a first magnetic strip 15 extending vertically. The first magnetic strip 15 has a first slot 16 and a second slot 17 extending vertically on both sides.

[0065] The first telescopic rod 121 and the second telescopic rod 122 are each provided with a first magnet 18, a first clearance groove 19 and a second clearance groove 20 at the end facing the seat body 1. The first clearance groove 19 and the second clearance groove 20 are located on both sides of the first magnet 18. The bottom of the first clearance groove 19 extends outward in a direction away from the first magnet 18 to form a first sliding hole 191. The bottom of the second clearance groove 20 extends outward in a direction away from the first magnet 18 to form a second sliding hole 201.

[0066] The first clearance groove 19 is provided with a first buckle 21 that engages with the first slot 16. The bottom of the first buckle 21 is connected to a first sliding rod 22. One end of the first sliding rod 22 extends out of the first sliding hole 191. The other end of the first sliding rod 22 and the inner wall of the first clearance groove 19 are provided with an elastic reset member. The first sliding rod 22 slides left and right along the first sliding hole 191.

[0067] The second clearance groove 20 is provided with a second buckle 23 that engages with the second slot 17. The bottom of the second buckle 23 is connected to a second sliding rod 24. One end of the second sliding rod 24 extends out of the second sliding hole 201. The other end of the second sliding rod 24 is provided with an elastic reset member between the inner wall of the second clearance groove 20. The second sliding rod 24 slides left and right along the second sliding hole 201.

[0068] The top of the first buckle 21 and the second buckle 23 are both provided with a snap-fit ​​part, and the first slot 16 and the second slot 17 are both provided with a stop step for blocking each snap-fit ​​part.

[0069] A button is provided at one end of the first sliding rod 22 that extends out of the first sliding hole 191, and a button is provided at one end of the second sliding rod 24 that extends out of the second sliding hole 201.

[0070] Specifically, taking the first telescopic rod 121 as an example, when the operator simultaneously presses the buttons at the top of the first sliding rod 22 and the second sliding rod 24, the first sliding rod 22 slides to the right in the first sliding hole 191, and the second sliding rod 24 slides to the left in the second sliding hole 201. This causes the first sliding rod 22 and the second sliding rod 24 to move the first latch 21 and the second latch 23 towards each other. The engaging part of the first latch 21 disengages from the stop step on the first slot 16, and the engaging part of the second latch 23 disengages from the stop step on the second slot 17. This disengages the first latch 21 and the second latch 23 from the engaging state with the first slot 16 and the second slot 17, respectively. At this time, the first telescopic rod 121 relies solely on the magnet at the bottom of the telescopic rod and the mounting rail 102. The magnetic attraction between the magnetic strips inside allows the operator to apply a force sufficient to overcome the magnetic attraction to the first telescopic rod 121, thereby moving the first telescopic rod 121 and adjusting its vertical position relative to the mounting track 102. After adjustment, the first telescopic rod 121 is reattached to the mounting track 102. The buttons at the top of the first sliding rod 22 and the second sliding rod 24 are then released. The first sliding rod 22 and the second sliding rod 24 are reset under the action of the elastic reset member, causing the locking part of the first buckle 21 to engage with the stop step of the first slot 16 and the locking part of the second buckle 23 to engage with the stop step of the second slot 17, thus re-engaging the first buckle 21 and the second buckle 23 with the first slot 16 and the second slot 17.

[0071] The dual sliding rods drive the buckles to move in opposite directions, ensuring that the buckles on both sides disengage from the slots simultaneously, avoiding the risk of uneven load caused by unlocking on one side. The combination of buckles and magnetic attraction combines the advantages of magnetic constraint and mechanical locking, taking into account both ease of adjustment and operational stability.

[0072] Specifically, such as Figure 6 and Figure 7As shown, the guide rail 13 has an elongated mounting hole 25 at one end facing the seat body 1, and two second magnetic strips 26 extending along the length of the guide rail 13 are spaced apart at the bottom end of the guide rail 13.

[0073] Each massager 14 includes a housing 27, and a slider 28 is connected to one end of each housing 27 facing the guide rail 13. The height of each slider 28 is less than the height of the mounting elongated hole 25. The two ends of the slider 28 in the length direction are provided with second magnets 29 that cooperate with the second magnetic strip 26.

[0074] Specifically, during installation, the slider 28 is passed through the mounting elongated hole 25 in a vertical direction and then rotated 90° around the axis of the housing 27, so that the second magnets 29 at both ends of the slider 28 are magnetically attracted to the second magnetic strip 26 preset on the inner wall of the guide rail 13, and the massager 14 is fixed by magnetic adsorption force.

[0075] Specifically, the housing 27 integrates a battery compartment and a drive assembly. The drive assembly includes a miniature DC motor and an eccentric wheel transmission mechanism. A lithium battery is installed in the integrated battery compartment, which powers the miniature DC motor. The motor output shaft drives the eccentric wheel to rotate via a coupling. During the high-speed rotation of the eccentric wheel, the massage head 36 generates high-frequency vibrations, achieving massage of the chest and abdomen.

[0076] Specifically, such as Figure 8 As shown, each massager 14 also includes a heating plate 34 installed on the side of the housing 27 near the massage head 36. The heating plate 34 is filled with heating wires, and four far-infrared lamps 35 are also installed on the heating plate 34 in a centrally symmetrical arrangement. The integrated battery compartment is also used to supply power to the heating wires and far-infrared lamps 35. The four far-infrared lamps 35 expand capillaries and increase the local temperature through thermal radiation. The heating wires heat the skin surface through conduction, relax muscles and reduce the sensitivity of pain nerves, so as to achieve heat therapy on the chest and abdomen of the human body.

[0077] Specifically, such as Figure 9 and Figure 10 As shown, the spa massage chair also includes a temperature sensor 43;

[0078] The drive unit includes an air pump 42 and a water pump 41;

[0079] The water tank includes a first water tank 30, a second water tank 31, and a third water tank 32 that are interconnected. The first water tank 30 is connected to the return channel 9, and a water exchange port 33 is provided on the side wall of the first water tank 30. Through the water exchange port 33, the user can add water to the first water tank 30 or release water from the first water tank.

[0080] The second water tank 31 is equipped with a heating device, the third water tank 32 is equipped with a cooling device, and the water pump 41 is located at the water inlet of the second water tank 31 and the third water tank 32.

[0081] Water pump 41 supplies water from the first water tank 30 to the second water tank 31 and the third water tank 32, respectively producing hot and cold water. The mixing pipes at the outlets of the second water tank 31 and the third water tank 32 are connected to the inlet of the air pump 42 after passing through the temperature sensor 43. The temperature of the water outlet is monitored in real time by the temperature sensor. The air inlet of the air pump 42 is connected to the outside air. The air-water outlet of the air pump 42 is connected to each multi-hole nozzle 6 and each single-hole nozzle 7 to form a heated water-air mixture, which is sprayed onto the waterproof membrane 8 through each multi-hole nozzle 6 and each single-hole nozzle 7 to achieve hydrotherapy massage for the human body.

[0082] The seat body 1 is provided with five surface landmarks, including the seventh cervical vertebra spinous process landmark 37, two acromion landmarks 38 and two iliac crest landmarks 39. The seventh cervical vertebra spinous process landmark 37 is located in the middle of the upper front side of the seat body 1, the two acromion landmarks 38 are located in the upper front side of the seat body 1, and the two iliac crest landmarks 39 are located on both sides of the front side of the seat body 1.

[0083] A seat cushion is located on top of the water tank at the bottom of the seat body 1.

[0084] The bottom of the seat body 1 is connected to a lifting rod, and the bottom of the lifting rod is equipped with several universal wheels.

[0085] A headrest cushion 40 is installed on the top of the seat body 1.

[0086] In other embodiments, the slot structure may be omitted, and magnets may be provided only on the first and second telescopic rods, with magnetic strips provided on the first and second mounting tracks, so that the first and second telescopic rods can be detachably connected by magnetic attraction.

[0087] In other embodiments, the scanning head may not be placed in the spinal groove.

[0088] The working process of this utility model is as follows:

[0089] Water is injected into the first water tank through the water inlet. The person sits on the seat with their back against the waterproof membrane. The water pump draws water from the first water tank into the second and third water tanks. The second water tank's air pump outlet sprays high-pressure water from the nozzle. The water flow impacts the waterproof membrane, massaging acupoints on the back. The water then flows down to the return channel and back into the first water tank. The first and second telescopic rods are installed on the seat. The length and height of the first and second telescopic rods are adjusted. The massager on the middle rod is turned on, providing heat therapy and massage to the chest and abdomen.

[0090] In summary, this utility model provides a spa massage chair that uses a waterproof membrane to prevent water from splashing directly from the nozzles and a return channel to recycle water, solving the problem of limited usage scenarios caused by water splashing in traditional spa massagers. It can be used safely in non-bathroom environments. Furthermore, it adds a detachable chest and abdominal massage structure that can slide up and down and back and forth relative to the seat body, expanding the massage area coverage and achieving coordinated massage of the back and chest / abdomen.
