The housing assembly is also provided with a liquid outlet that is connected to the liquid guiding chamber. The drive assembly is disposed inside the housing assembly. The power output end of the drive assembly is connected to the rotating shaft and is used to drive the rotating shaft to rotate. The rotating shaft extends into the liquid guiding chamber. The outer peripheral wall of the rotating shaft bulges radially toward the cavity wall of the liquid guiding chamber to form a spiral protrusion. When the rotating shaft rotates, it can squeeze the liquid in the liquid guiding chamber through the liquid outlet through the spiral protrusion.
[0005] Compared with the prior art, the beneficial effects of the liquid dispensing device provided in this application are as follows: During operation, the liquid in the storage chamber is replenished into the liquid guiding chamber, and the rotating shaft is driven by the drive component to rotate. When the rotating shaft rotates, the liquid in the liquid guiding chamber is squeezed out through the liquid outlet through the spiral protrusions on the outer peripheral wall, thus realizing automatic liquid dispensing. Compared with the traditional method of manually pressing the nozzle repeatedly to squeeze the liquid out of the container, the operation is more convenient and the liquid dispensing is smoother. In addition, the drive component can control the liquid dispensing speed by controlling the rotation speed of the rotating shaft, thereby enabling precise control of the liquid dispensing volume.
[0006] Furthermore, the spiral protrusions seal against the wall of the fluid guiding cavity.
[0007] Furthermore, the outlet is positioned directly opposite one end of the rotating shaft, the shaft diameter gradually decreases in the direction away from the outlet, and the size of the spiral protrusion along the radial direction of the rotating shaft gradually decreases in the direction closer to the outlet.
[0008] Furthermore, the housing assembly includes a housing and a flexible rubber component. The drive assembly is disposed inside the housing. The flexible rubber component is connected to and cooperates with the housing to form a liquid guiding cavity. The liquid outlet is located in the flexible rubber component. The liquid guiding cavity is connected to the inner cavity of the housing so that the rotating shaft can extend into the liquid guiding cavity. The spiral protrusion seals against the flexible rubber component.
[0009] Furthermore, the liquid dispensing device also includes a sealing ring, which is fitted onto the power output end of the drive assembly and abuts against the inner wall of the encapsulation housing.

[0013] Furthermore, a silver layer is provided on the surface of the rotating shaft and the spiral protrusion.
[0014] On the other hand, in order to achieve the above objectives, the technical solution adopted in this application is: a massage device, including a massager body and the above-mentioned liquid dispensing device, wherein the liquid dispensing device is disposed on the massager body.
[0015] Compared with existing technologies, the beneficial effects of the massage device provided in this application are as follows: When using the main body of the massager to massage the human skin, liquids such as essential oils, skin lotions, and liniments can be squeezed out of the skin through the liquid dispensing device. The liquid in the storage chamber is replenished into the guiding chamber, and the rotating shaft is driven by the drive component to rotate. When the shaft rotates, the liquid in the guiding chamber is squeezed out through the liquid outlet through the spiral protrusions on the outer peripheral wall, thus realizing automatic liquid dispensing. Compared with the traditional method of repeatedly pressing the nozzle to squeeze out the liquid in the container, the operation is more convenient and the liquid dispensing is smoother. In addition, the drive component can control the liquid dispensing speed by controlling the rotation speed of the rotating shaft, thereby enabling precise control of the liquid dispensing volume.

[0035] Combination Figure 1 and Figure 2As shown in the figure, this application provides a liquid dispensing device, including a housing assembly 10, a drive assembly 20, and a rotating shaft 30. The housing assembly 10 is provided with a liquid storage chamber 131 and a liquid guiding chamber 121 that are connected to each other. The housing assembly 10 is also provided with a liquid outlet 1221 that is connected to the liquid guiding chamber 121. The drive assembly 20 is disposed inside the housing assembly 10. The power output end of the drive assembly 20 is connected to the rotating shaft 30 and is used to drive the rotating shaft 30 to rotate. The rotating shaft 30 extends into the liquid guiding chamber 121. The outer peripheral wall of the rotating shaft 30 protrudes radially toward the cavity wall of the liquid guiding chamber 121 to form a spiral protrusion 40. When the rotating shaft 30 rotates, it can squeeze the liquid in the liquid guiding chamber 121 through the liquid outlet 1221 through the spiral protrusion 40.
[0036] During operation, the liquid in the storage chamber 131 is replenished into the liquid guiding chamber 121. The drive assembly 20 drives the rotating shaft 30 to rotate. When the rotating shaft 30 rotates, the liquid in the liquid guiding chamber 121 is squeezed out through the liquid outlet 1221 through the spiral protrusion 40 on the outer peripheral wall, thus realizing automatic liquid dispensing. Compared with the traditional method of manually pressing the nozzle repeatedly to squeeze out the liquid in the container, the operation is more convenient and the liquid dispensing is smoother. In addition, the drive assembly 20 can control the liquid dispensing speed by controlling the rotation speed of the rotating shaft 30, thereby enabling precise control of the liquid dispensing volume.
[0037] The liquid storage chamber 131 can be located above the liquid guiding chamber 121, so that the liquid in the liquid storage chamber 131 can automatically flow into the liquid guiding chamber 121 under the action of gravity. Of course, the liquid in the liquid storage chamber 131 can also be transported to the liquid guiding chamber 121 by a power device.
[0038] Users can add liquids such as essential oils, skin lotions, and liniments to the storage chamber 131 as needed. When cleaning is required, the drive assembly 20 drives the rotating shaft 30 to rotate, and the user can add clean water to the storage chamber 131. The clean water flows from the storage chamber 131 into the guide chamber 121. The rotating shaft 30 rotates and, through the spiral protrusion 40, squeezes the clean water in the guide chamber 121 out through the outlet 1221, thereby achieving automatic cleaning of the storage chamber 131, the guide chamber 121, the rotating shaft 30, and the spiral protrusion 40. No manual cleaning or disassembly is required, making operation convenient.
[0039] Specifically, such as Figure 3 As shown, the helical protrusion 40, in conjunction with the rotating shaft 30, forms a continuous helical flow channel 50 on the outer circumference of the rotating shaft 30. When the rotating shaft 30 and the helical protrusion 40 rotate, the helical protrusion 40 pushes the liquid along the helical flow channel 50. After flowing out of the helical flow channel 50, the liquid is squeezed out through the outlet 1221 under pressure. Specifically, the rotating shaft 30 can be a screw, and the helical protrusion 40 can be the helical teeth on the screw. Of course, the helical protrusion 40 can also be a helical blade.
[0040] In one embodiment, the liquid outlet 1221 is in the shape of a straight line. By setting the liquid outlet 1221 to a narrow straight line, liquid leakage can be effectively avoided or reduced when the drive component 20 is not working. When the drive component 20 is working, the liquid in the liquid guiding cavity 121 can be squeezed out through the liquid outlet 1221 under the push of the spiral protrusion 40.
[0041] In one embodiment, combined Figure 1 and Figure 2 As shown, the spiral protrusion 40 is in sealed contact with the wall of the liquid guiding cavity 121. By sealing the spiral protrusion 40 with the wall of the liquid guiding cavity 121, the liquid can be prevented from flowing freely in the gap between the spiral protrusion 40 and the wall of the liquid guiding cavity 121, ensuring that the liquid flows only along the spiral flow channel 50 formed by the cooperation of the spiral protrusion 40 and the rotating shaft 30. This improves the liquid conveying efficiency and makes it easier for the liquid to be squeezed out through the outlet 1221.
[0042] In one embodiment, combined Figure 1 and Figure 3 As shown, the outlet 1221 is positioned directly opposite one end of the rotating shaft 30. The rotating shaft 30 is conical, and its diameter gradually decreases towards the direction away from the outlet 1221. The radial dimension of the spiral protrusion 40 gradually decreases towards the direction closer to the outlet 1221. The radial dimension of the spiral protrusion 40 is its height h. By gradually decreasing the height h of the spiral protrusion 40 towards the outlet 1221, while the diameter of the rotating shaft 30 gradually decreases towards the direction away from the outlet 1221, the depth of the spiral flow channel 50 formed by the rotating shaft 30 and the spiral protrusion 40 gradually decreases towards the outlet 1221. In principle, this is similar to the shrinking of the water outlet of a water pipe. This arrangement facilitates liquid extrusion and increases the liquid extrusion speed. Specifically, the rotating shaft 30 and the helical protrusion 40 are formed simultaneously on a section of cylinder by creating helical grooves. The depth of the helical grooves is gradually reduced during their creation, causing the shaft diameter of the rotating shaft 30 and the height h of the helical protrusion 40 to gradually increase and decrease in the same direction, respectively. Since the outer diameter of the helical protrusion 40 remains constant, it ensures that all parts of the helical protrusion 40 along the axial direction of the rotating shaft 30 are in sealed contact with the wall of the liquid guiding cavity 121.
[0043] In one embodiment, combined Figure 1 , Figure 2 and Figure 4As shown, the housing assembly 10 includes a housing 11 and a flexible plastic component 12. A drive assembly 20 is disposed within the housing 11. The flexible plastic component 12 is connected to the housing 11 and engages with a liquid guiding cavity 121. A liquid outlet 1221 is located on the flexible plastic component 12. The liquid guiding cavity 121 communicates with the inner cavity of the housing 11 to allow the rotating shaft 30 to extend into the liquid guiding cavity 121. The spiral protrusion 40, facing away from the peripheral wall of the rotating shaft 30, seals against the flexible plastic component 12. By sealing the spiral protrusion 40 against the flexible plastic component 12, and given the elasticity of the flexible plastic component 12, the sealing effect is enhanced. The housing 11 can be made of a rigid material to ensure strength. The housing 11 and the flexible plastic component 12 can be integrally molded using a secondary injection molding process, or they can be manufactured separately and then assembled and fixed.
[0044] In one embodiment, combined Figure 1 and Figure 2 As shown, the encapsulation housing 11 has a fixing tube 1121, and the soft plastic part 12 includes a base 122 and a tube body 123 disposed on the base 122. The liquid guiding cavity 121 is at least partially formed in the tube body 123, and the liquid outlet 1221 is disposed on the base 122. The outer wall of the tube body 123 is connected to the inner wall of the fixing tube 1121. The rotating shaft 30 can be inserted into the tube body 123 from the end of the tube body 123 away from the base 122. The spiral protrusion 40 seals against the inner wall of the tube body 123. Specifically, the tube body 123 and the fixing tube 1121 can be integrally formed by secondary injection molding. It should be noted that the liquid guiding cavity 121 can be completely formed in the tube body 123, that is, the cavity of the tube body 123 is the liquid guiding cavity 121, or the liquid guiding cavity 121 can be partially formed in the tube body 123 and partially extend into the encapsulation housing 11.
[0045] In one embodiment, such as Figure 1 As shown, the power output end of the drive assembly 20 is an output gear 221, and the rotating shaft 30 is fixedly connected to the output gear 221. By driving the output gear 221 to rotate, the rotating shaft 30 is driven to rotate. The output gear 221 and the rotating shaft 30 can be integrally formed, or they can be manufactured separately and then assembled. Specifically, as shown... Figure 4 As shown, the drive assembly 20 includes a motor 21 and a gear transmission assembly 22. The motor 21 is connected to the gear transmission assembly 22 and is used to drive the gear transmission assembly 22 to rotate. The gear transmission assembly 22 includes multiple meshing gears, and the gear located at the end of the power transmission path is the output gear 221. Transmission through the gear transmission assembly 22 has the advantages of stable transmission and low noise.
[0046] In one embodiment, such as Figure 1As shown, the liquid discharge device also includes a sealing ring 60, which is sleeved on the power output end of the drive assembly 20, that is, on the output gear 221, and abuts against the inner wall of the encapsulation housing 11, thereby preventing the liquid in the liquid guiding cavity 121 from flowing into the interior of the encapsulation housing 11 and causing damage to the drive assembly 20.
[0047] In one embodiment, combined Figure 1 and Figure 3 As shown, the rotating shaft 30 is fixedly connected to one side of the output gear 221. The output gear 221 is connected to one side of the rotating shaft 30 and has an annular groove 2211 surrounding the rotating shaft 30. An annular protrusion 1122 is provided on the inner wall of the encapsulation housing 11. The annular protrusion 1122 is inserted into the annular groove 2211. The sealing ring 60 is disposed in the annular groove 2211 and located inside the annular protrusion 1122. The outer ring surface of the sealing ring 60 abuts against the annular protrusion 1122, and the inner ring surface of the sealing ring 60 abuts against the side wall of the annular groove 2211, thereby achieving a seal.
[0048] In one embodiment, combined Figure 4 and Figure 5 As shown, the enclosure housing 11 includes an upper housing 111 and a lower housing 112. The upper housing 111 is detachably connected to the lower housing 112. By disassembling the upper housing 111, the drive assembly 20 and the rotating shaft 30 can be easily installed and removed. The upper housing 111 and the lower housing 112 can be fixed together with screws. The aforementioned fixing tube 1121 and annular protrusion 1122 are both provided on the lower housing 112.
[0049] In one embodiment, combined Figure 1 and Figure 4As shown, the housing assembly 10 also includes a liquid storage housing 13, which has a liquid storage chamber 131 and a first through hole 1321 communicating with the liquid storage chamber 131. The encapsulation housing 11 has a second through hole 1123 communicating with the liquid guiding chamber 121. The liquid dispensing device also includes a connecting pipe 70, whose two ends are respectively connected to the first through hole 1321 and the second through hole 1123. Liquid in the liquid storage chamber 131 can be replenished into the liquid guiding chamber 121 through the first through hole 1321, the connecting pipe 70, and the second through hole 1123 in sequence. Since the tube body 123 of the soft rubber part 12 is located inside the fixing tube 1121 of the encapsulation housing 11, the second through hole 1123 is opened on the encapsulation housing 11. After the liquid passes through the second through hole 1123, it can flow into the tube body 123 from the end of the tube body 123 away from the base 122. In some other embodiments, the flexible component 12 can be connected to the outside of the encapsulation housing 11. In this case, a second through hole 1123 can be formed on the flexible component 12, allowing liquid to flow directly into the tube body 123 after passing through the second through hole 1123. It should be noted that the second through hole 1123 is located above the tube body 123. In this case, the portion of the internal space of the encapsulation housing 11 located between the second through hole 1123 and the tube body 123 also belongs to the liquid guiding cavity 121, which together with the lumen of the tube body 123 constitutes the liquid guiding cavity 121.
[0050] In one embodiment, the liquid storage housing 13 has a first connecting post with a first through hole 1321, and the encapsulation housing 11 has a second connecting post with a second through hole 1123. The two ends of the connecting tube 70 are respectively sleeved on the first and second connecting posts, allowing liquid in the liquid storage chamber 131 to flow into the liquid storage chamber 131 sequentially through the first through hole 1321, the connecting tube 70, and the second through hole 1123. Specifically, the connecting tube 70 can be a retractable flexible tube, which facilitates assembly and allows for a sealed fit on the first and second connecting posts to prevent leakage. Specifically, the second connecting post is vertically connected to the outer circumferential surface of the fixed tube 1121. Liquid enters the fixed tube 1121 through the second through hole 1123 of the second connecting post, and then flows into the liquid guiding chamber 121 from the end of the tube body 123 of the soft rubber part 12 away from the base 122.
[0051] In one embodiment, combined Figure 1 and Figure 4 As shown, the liquid storage housing 13 includes a liquid storage support 132 and a cover 133. The cover 133 is detachably connected to the liquid storage support 132. The liquid storage support 132 and the cover 133 cooperate to form a liquid storage cavity 131. A first through hole 1321 is provided in the liquid storage support 132. The user can add liquid to the liquid storage cavity 131 by removing the cover 133.
[0052] In one embodiment, combinedFigure 1 and Figure 4 As shown, the housing assembly 10 also includes a housing 14 with an opening. The liquid storage support 132, the encapsulation housing 11, the flexible plastic part 12, the drive assembly 20, and the rotating shaft 30 are all disposed inside the housing 14. A cover 133 is detachably connected to the housing 14 and seals the opening. During assembly, the liquid storage support 132, the encapsulation housing 11, the flexible plastic part 12, the drive assembly 20, and the rotating shaft 30 are inserted into the housing 14 through the opening, and then the cover 133 is used to seal the opening of the housing 14, thereby encapsulating the liquid storage support 132, the encapsulation housing 11, the flexible plastic part 12, the drive assembly 20, and the rotating shaft 30. While sealing the opening of the housing 14, the cover 133 also cooperates with the liquid storage support 132 to form a liquid storage cavity 131. This eliminates the need for two covers 133 to separately seal the opening and cooperate with the liquid storage support 132, thus simplifying the device structure and facilitating the addition of liquid to the liquid storage cavity 131. Specifically, the opening is located at the top of the outer casing 14. The encapsulation housing 11 can be fixedly connected to the outer casing 14 by screws. The liquid storage bracket 132 is located at the top of the encapsulation housing 11. The outer periphery of the liquid storage bracket 132 can be welded or glued to the inner wall of the outer casing 14. Specifically, ultrasonic welding can be used to not only achieve fixation but also to seal and waterproof, preventing external liquid from flowing into the interior of the outer casing 14 from between the liquid storage bracket 132 and the outer casing 14 and causing damage to the drive assembly 20.
[0053] In one embodiment, such as Figure 1 As shown, a first sealing ring 1331 is provided on the inner wall of the cover 133. The first sealing ring 1331 abuts against the outer wall of the outer shell 14, which not only plays a certain role in fixing the cover 133 so that the cover 133 is not easy to fall off, but also achieves a seal to prevent external liquid from flowing into the outer shell 14.
[0054] In one embodiment, such as Figure 1 As shown, the soft rubber component 12 is sealed against the inner wall of the outer shell 14. The soft rubber component 12 divides the inner cavity of the outer shell 14 into a first space 141 and a second space 142. The encapsulated shell 11 is located in the first space 141, and the liquid outlet 1221 is connected to the second space 142. The outer shell 14 is provided with a liquid guiding hole 1431 connected to the second space 142. The liquid in the liquid guiding cavity 121 is squeezed out through the liquid outlet 1221 and first enters the second space 142, and then is discharged to the outside of the outer shell 14 through the liquid guiding hole 1431. By sealing the soft rubber component 12 against the inner wall of the outer shell 14, liquid can be prevented from flowing from the second space 142 into the first space 141 and causing damage to the drive assembly 20. Specifically, a second sealing ring strip 1222 is provided on the outer periphery of the base 122 of the soft rubber component 12, and the second sealing ring strip 1222 is sealed against the inner wall of the outer shell 14.
[0055] In one embodiment, such as Figure 1 As shown, the outer casing 14 has multiple liquid guiding columns 143, and each liquid guiding column 143 has a liquid guiding hole 1431. By providing multiple liquid guiding columns 143, the liquid in the second space 142 can be discharged to the outside of the outer casing 14 through the liquid guiding holes 1431 of the multiple liquid guiding columns 143, thereby increasing the liquid discharge range.
[0056] In one embodiment, a silver layer is provided on the surfaces of both the rotating shaft 30 and the spiral protrusion 40. By forming a silver layer by plating the surfaces of the rotating shaft 30 and the spiral protrusion 40 with silver, a bactericidal effect can be achieved, thereby preventing the growth of bacteria and the generation of odors due to incomplete cleaning.
[0057] In one embodiment, such as Figure 4 As shown, the liquid dispensing device also includes an electrical connector 80, which is electrically connected to the drive assembly 20 and extends at least partially out of the housing 14. This connector can be used to electrically connect to an external power supply system and control system to power and control the drive assembly 20. Specifically, the electrical connector 80 can be a set of conductive pins.
[0058] This application also provides a massage device, including a massager body and a liquid dispensing device provided in any of the above embodiments, the liquid dispensing device being disposed on the massager body. The massager body is provided with conductive contacts, and the conductive pin group of the liquid dispensing device is connected to the conductive contacts, thereby enabling the massager body to supply power and control the driving assembly 20 of the liquid dispensing device.
[0059] When using the massager to massage the skin, liquids such as essential oils, lotions, and liniments can be dispensed onto the skin through the liquid dispensing device. The liquid in the storage chamber 131 is replenished into the guiding chamber 121. The drive assembly 20 drives the rotating shaft 30 to rotate. When the rotating shaft 30 rotates, the liquid in the guiding chamber 121 is squeezed out through the liquid outlet 1221 through the spiral protrusions 40 on the outer peripheral wall. This achieves automatic liquid dispensing. Compared with the traditional method of manually pressing the nozzle repeatedly to squeeze out the liquid from the container, the operation is more convenient and the liquid dispensing is smoother. In addition, the drive assembly 20 can control the dispensing speed by controlling the rotation speed of the rotating shaft 30, thereby enabling precise control of the dispensing volume.
[0060] The type of massager body is not limited; it can be a massage comb, a back massager, a neck massager, a fascia gun, etc.
