[0048] like Figures 1 to 7As shown, according to the first aspect of the embodiment of the utility model, a liquid adding device 100 is proposed, which is applied to a massager. The liquid adding device 100 includes a power component 10 and an extrusion component 20. The power component 10 and the extrusion component 20 can be connected by a connecting piece. The power component 10 includes a driving member 11, and the driving member 11 is used to generate a driving force; the extrusion component 20 includes a liquid storage tank 21, a piston 22 and a transmission member 23. The liquid storage tank 21 includes a storage area 211. The liquid storage tank 21 is provided with a liquid outlet 212, and the liquid outlet 212 is connected to the storage area 211; the piston 22 is slidably arranged inside the liquid storage tank 21, and the volume of the storage area 211 changes through the movement of the piston 22; the driving member 11 is connected to the transmission member 23, and through the cooperation of the transmission member 23 and the piston 22, the piston 22 moves in a direction close to the liquid outlet 212, so as to quantitatively extrude the liquid in the liquid storage tank 21 through the liquid outlet 212.

[0049] It should be noted that the number of the liquid outlets 212 here is one or more, which can be set according to the number of massage heads of the massager. When the number of the liquid outlets 212 is more than one, the multiple liquid outlets 212 are arranged at intervals along the bottom of the liquid storage tank 21, so that the liquid in the storage area 211 can be squeezed out from the multiple liquid outlets 212 at the same time. The driving member 11 can be a motor or other power output component that can achieve power output. In addition, the liquid here can be selected according to the function of the massager. For example, when massaging the scalp, the liquid can be shampoo or conditioner, etc.; when massaging the face or neck, the liquid can be skin care lotion, active oil or essential oil, etc., so that the massager has more uses and more powerful functions.

[0050] In the related art, elastic parts such as springs are usually used to realize the extrusion function by means of structures such as elastic parts and ball bearings. Users press to make the essential oil flow out during use. In actual use, due to different working conditions, the outflow of essential oil is uncontrollable and the process is not smooth.

[0051] The liquid adding device 100 in the utility model connects the driving member 11 to the transmission member 23 and cooperates with the transmission member 23 and the piston 22, so that the piston 22 can generate movement in the direction close to the liquid outlet 212, thereby reducing the volume of the storage area 211, so that the liquid in the liquid storage tank 21 can be quantitatively squeezed out through the liquid outlet 212, so that the liquid in the liquid storage tank 21 can be quantitatively squeezed into the massager, the outflow of the liquid can be accurately controlled, and in the process of liquid extrusion, the liquid extrusion is smoother.

[0052] The specific structure of the extrusion assembly 20 will be introduced below.

[0053] Alternatively, if Figure 6As shown, the transmission member 23 is rotatably disposed on the liquid storage tank 21, a pin 24 is provided on the outer side surface of the transmission member 23, and a piston 22 is sleeved on the outer side surface of the transmission member 23, a part of the piston 22 is disposed in the slide groove 213, and a spiral groove 2211 is provided on the side of the piston 22 facing the transmission member 23, and the pin 24 is inserted into the spiral groove 2211, so that the piston 22 can generate a linear motion in a first direction along the inner wall of the liquid storage tank 21 through the rotation of the transmission member 23; the first direction is the axial direction of the liquid storage tank 21.

[0054] Specifically, Figure 2 As shown, the transmission member 23 is provided with a mounting hole 231 on the side near the bottom end along the first direction. There is one mounting hole 231 for mounting the pin 24. Through the interaction between the pin 24 and the spiral groove 2211, the piston 22 generates a linear motion along the first direction. When the piston 22 moves downward, the liquid is squeezed into the massage head of the massager.

[0055] Optionally, an opening 233 is provided at one end of the transmission member 23 facing the cover body 14, and the transmission member 23 encloses a receiving space 234 communicating with the opening 233. The receiving space 234 can be used to receive some components of the power assembly 10, such as the driving member 11 and the bracket 12, etc., thereby saving the space occupied by the entire liquid adding device 100, making the structure of the liquid adding device 100 more compact.

[0056] Alternatively, if Figures 1 to 6 As shown, a portion of the inner side surface of the liquid storage tank 21 is provided with a slide groove 213, and the slide groove 213 extends along a first direction. The piston 22 includes a body portion 221 and a boss 222. Along the first direction, the boss 222 is arranged at the upper part of the side surface of the body portion 221, and at least a portion of the boss 222 is accommodated in the slide groove 213. The boss 222 here can limit the movement stroke of the piston 22. When the boss 222 contacts the bottom of the slide groove 213 along the first direction, the piston 22 will not be able to move further, and the volume of the storage area 211 cannot be further reduced.

[0057] The first direction here is the XX direction, and the maximum stroke of the piston 22 is the dimension of the slide groove 213 along the first direction.

[0058] There are two bosses 222, which are respectively arranged at two opposite positions of the body 221, that is, the line connecting the center lines of the two bosses 222 passes through the axial surface of the body 221. The boss 222 can be a rectangular block, and the surface of the boss 222 facing the body 221 can be matched with the arc surface of the body 221.

[0059] When the piston 22 moves downward along the first direction XX, the volume of the storage area 211 will be reduced, so that the liquid is squeezed out of the storage area 211 .

[0060] Optionally, a sealing structure is provided between the outer periphery of the piston 22 and the inner wall of the liquid storage tank 21 to reduce the probability of the liquid moving upward along the contact surface between the piston 22 and the liquid storage tank 21 and reduce the probability of the liquid entering the first slide groove 213.

[0061] It should be noted that there are many structures for sealing the outer periphery of the piston 22 and the inner wall of the liquid storage tank 21, such as a structure in which a sealing surface is used for sealing or a sealing member is used for sealing.

[0062] In the present invention, a sealing ring 25 is used for sealing. Specifically, Figure 3 and Figure 4 As shown, the sealing structure includes a sealing ring 25, and at least one of the outer side surface of the piston 22 and the inner side surface of the liquid storage tank 21 is provided with a groove 223, and the groove 223 is used to install the sealing ring 25. That is to say, the sealing ring 25 is installed in an embedded installation manner, so that the sealing between the piston 22 and the liquid storage tank 21 can be achieved.

[0063] The number of the sealing ring 25 is one or more, and the plurality of sealing rings 25 are arranged at intervals along the axial direction of the piston 22. Figure 3 In the embodiment, there are two sealing rings 25 , and two grooves 223 are provided on the outer side of the piston 22 , and the two sealing rings 25 are respectively arranged in the two grooves 223 .

[0064] The sealing ring 25 here is a circular ring structure, and can be made of soft materials such as silicone or rubber.

[0065] The following description will focus on the structure of the power assembly 10 .

Figure 1 In the embodiment, the number of the first connecting members 30 is three. Figure 2 In the embodiment, the number of the second connecting members 15 is four.

[0068] The speed reducer 13 here mainly plays the role of reducing speed and increasing torque. The speed reducer 13 will be described below as a gear speed reduction structure.

[0069] Optionally, the speed reducer 13 includes a first gear 131, the first gear 131 includes a first sub-gear 1311 and a second sub-gear 1312 arranged coaxially, wherein the first sub-gear 1311 is meshedly connected with the output gear 111 of the driving member 11, and accordingly, the extrusion assembly 20 also includes a second gear 26, the second gear 26 is arranged on the liquid storage tank 21, and the second gear 26 includes a third sub-gear 261 and a fourth sub-gear 262 arranged coaxially, wherein the second sub-gear 1312 and the third sub-gear 261 are meshedly connected; the transmission member 23 includes a third gear 232, and the third gear 232 is meshedly connected with the fourth sub-gear 262. Through this structure, the power of the power member can be transmitted to the second gear 26, and then to the third gear 232, so that the power of the power member can be transmitted to the power member to realize the rotation of the power member.

[0070] An output gear 111 is disposed on the output shaft of the driving member 11 , and the axial direction of the output shaft of the driving member 11 is consistent with the direction of liquid extrusion, both being XX direction, and has the advantages of simple structure and high transmission efficiency.

[0071] It should be noted that the liquid storage tank 21 here is a cylindrical structure as a whole. In order to facilitate the placement of the second gear 26, the liquid storage tank 21 also includes a protrusion 215. The protrusion 215 here can be of various shapes, which can increase the space enclosed by the liquid storage tank 21, so that the second gear 26 and other components can be installed in the space enclosed by the liquid storage tank 21.

[0072] Optionally, the speed reducer 13 further includes a first rotating shaft 132 , and the first rotating shaft 132 is used to install the first gear 131 , and the first rotating shaft 132 and the first gear 131 can rotate synchronously, thereby realizing power transmission.

[0073] Optionally, the bracket 12 and the liquid storage tank 21 enclose a space for accommodating the driving member 11 , the piston 22 and the transmission member 23 .

[0074] The bracket 12 is located at the upper part of the liquid adding device 100, and the liquid storage tank 21 is located at the lower part of the liquid adding device 100. The bracket 12 and the liquid storage tank 21 are connected to form a space capable of accommodating the driving member 11, the piston 22 and the transmission member 23. The bracket 12 and the liquid storage tank 21 can be directly connected by screws and other components.

[0075] Alternatively, the bracket 12 includes a first lug portion 121, and the liquid storage tank 21 includes a second lug portion 214. The first lug portion 121 and the second lug portion 214 are arranged correspondingly, and the first lug portion 121 and the second lug portion 214 are connected via a second connecting member 15. By adopting this method, the connection between the bracket 12 and the liquid storage tank 21 can be more conveniently achieved.

[0076] Among them, the number of the first lug portions 121 and the second lug portions 214 are both multiple, for example, the number of the first lug portions 121 and the second lug portions 214 are both three, and the three first lug portions 121 are arranged at intervals along the circumference of the bracket 12, and accordingly, the three second lug portions 214 are also arranged at intervals along the circumference of the liquid storage tank 21.
