Description

Technical Field

[0001] This utility model relates to the field of back massage technology, and in particular to a multifunctional back massage tool. Background Technology

[0002] Currently, in existing technologies, back massage typically uses roller massagers. For example, Chinese utility model patent CN201120572941.4 discloses a multi-effect roller massager for the waist, shoulders, and back, comprising upper and lower elastic plastic tubes. The two ends of the upper and lower elastic plastic tubes are respectively connected to left and right handles. At least seven massage balls are arranged between the upper and lower elastic plastic tubes. The surface of each massage ball has evenly distributed granular protrusions. The massage balls are connected between the upper and lower elastic plastic tubes by upper and lower support blocks. Seven massage balls are arranged between the two upper and lower elastic plastic tubes, and each massage ball has 12 granular protrusions as massage acupoints. This provides a back massage by pulling and rolling the back. However, it can only be used for massage and cannot be used for bathing or scrubbing the back, thus limiting its applicability. Unable to meet diverse user needs, back scrubbing products typically only offer back scrubbing without massage. They usually employ a pull-type back scrubbing strap, a strip made of special bath scrubbing cloth. To use it, the strap is placed on the back, and both hands pull from the right shoulder and left back, keeping the surface pressed against the skin. A diagonal up-and-down pulling motion is then performed, utilizing the friction between the strap and the skin to achieve the scrubbing effect. However, existing back massage and scrubbing products are limited in function, either only for back massage or only for bath scrubbing. Users need to purchase separate products for massage and scrubbing, resulting in high costs, inconvenience in storage and use, and a narrow range of applications, failing to meet diverse user needs.

[0032] This application provides a multifunctional back-rubbing massage tool to solve the technical problem of single function in the prior art. By setting massage rollers 200 and scrubbing parts 120 on the substrate 100 of multiple constituent units 10 respectively, the product has two functions: back-rubbing and massage, thereby meeting the user's needs for multiple different functions.

[0033] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please refer to the following: Figures 1 to 8 This embodiment provides a multifunctional back-rubbing massage tool, including:

[0035] Multiple constituent units 10 are rotatably connected to each other. Each constituent unit 10 includes a substrate 100 and at least one massage roller 200. The outer periphery of the massage roller 200 has massage protrusions 210. The substrate 100 has opposing first surfaces 101 and second surfaces 102. The substrate 100 has an accommodating space 110. The massage roller 200 is pivotally connected to the accommodating space 110, and the massage protrusions 210 of the massage roller 200 protrude from the first surface 101 and / or the second surface 102. The first surface 101 and / or the second surface 102 are provided with a scrubbing part 120.

[0036] As can be seen, the multifunctional back-rubbing massage tool of this embodiment includes multiple constituent units 10, which are rotatably connected to each other. Each constituent unit 10 includes a base plate 100 and at least one massage roller 200. The outer periphery of the massage roller 200 has massage protrusions 210. The base plate 100 has opposing first surfaces 101 and second surfaces 102. The base plate 100 has an accommodating space 110. The massage roller 200 is pivotally connected to the accommodating space 110, and the massage protrusions 210 of the massage roller 200 protrude from the first surface 101 and / or the second surface 102. The first surface 101 and / or the second surface 102 are provided with scrubbing surfaces. Thus, by providing a massage roller 200 and a scrubbing part 120 on the substrate 100, the product has both back scrubbing and massage functions, thereby meeting the user's various functional needs. In use, the massage protrusions 210 of the massage roller 200 roll against the back for massage, and the scrubbing part 120 on the substrate 100 can rub against the surface of the human skin for back scrubbing. Multiple adjacent constituent units 10 are rotatably connected, so that the massage protrusions 210 and the scrubbing part 120 can fit closely to the back, resulting in a better usage effect. The structural design is simple and compact, stable and reliable, with low processing difficulty and production cost, and simple and convenient operation.

[0037] In this embodiment, as Figures 1 to 5As shown, the scrubbing part 120 uses one or more of the following: scrubbing brush bristles, scrubbing towel, and scrubbing protrusions. The scrubbing part 120 is fixed to the first surface 101 and / or the second surface 102 of the base plate 100. When the back massage tool is used to perform diagonal upward and downward pulling movements on the back, the scrubbing part 120 contacts and rubs against the back skin to perform back scrubbing. In a preferred embodiment, the scrubbing part 120 using scrubbing brush bristles provides a better back scrubbing effect.

[0038] Specifically, such as Figures 1 to 5 As shown, the substrates 100 of multiple adjacent constituent units 10 are rotatably connected by flexible bands, elastic ropes, or pivot shafts. In a preferred embodiment, the substrates 100 of multiple adjacent constituent units 10 are rotatably connected by pivot shafts. During back massage, the substrates 100 of multiple adjacent constituent units 10 can be appropriately bent to fit closely to the back of the human body. Of course, flexible bands or elastic ropes can also be used to connect the substrates 100 of multiple adjacent constituent units 10, which can also achieve the effect of bending to fit closely to the back of the human body.

[0039] Furthermore, such as Figure 6 and Figure 7 As shown, the substrate 100 has a through groove from the first surface 101 to the second surface 102 to form an accommodating space 110, and the massage protrusions 210 of the massage roller 200 protrude from the first surface 101 and the second surface 102. Thus, when the back is pulled diagonally up and down, the massage roller 200 rolls in the accommodating space 110, and the massage protrusions 210 of the massage roller 200 can roll and massage the back of the human body. The massage protrusions 210 serve as massage stimulation points, and the pulling and rolling feel more comfortable, so as to relax muscles and tendons, promote blood circulation, eliminate fatigue, and slim and shape the body.

[0040] Among them, such as Figure 6 and Figure 7 As shown, the massage roller 200 has multiple massage protrusions 210 evenly arranged on its outer periphery. The cross-sectional shape of the massage protrusions 210 of the massage roller 200 is an ellipse or waist shape extending along the width direction, so as to increase the contact area between the massage protrusions 210 and the skin when the massage roller 200 rolls along the back of the human body, thereby realizing that the massage protrusions 210 of the massage roller 200 have the effect of pushing and pressing the back, further enhancing the massage effect.

[0041] Preferred, such as Figure 6 and Figure 7As shown, each constituent unit 10 has two accommodating spaces 110 spaced apart along its width direction on its base plate 100. Each accommodating space 110 is a strip-shaped hole extending along the length direction of the back-rubbing massage tool. Massage rollers 200 are rotatably mounted in each accommodating space 110, so that the massage protrusions 210 of the two massage rollers 200 can provide lateral support. This prevents severe lateral tilting when the back-rubbing massage tool is used for diagonal upward and downward pulling movements, improving the stability and reliability of the structural design. It should be understood that in the description of this utility model, the width direction refers to the width direction of the entire back-rubbing massage tool or... Figure 3 The left and right directions are shown.

[0042] Among them, such as Figure 5 As shown, in a preferred embodiment, the substrate 100 of the multiple constituent units 10 is uniformly provided with scrubbing bristles only on its second surface 102, and the length of the scrubbing bristles is greater than the maximum distance from the top of the massage protrusion 210 to the second surface 102 of the substrate 100, so that the scrubbing bristles can contact the human skin to scrub the back. When there is no need to scrub the back and only the back needs to be massaged, the first surface 101 of the back massage tool can be used to pull the back diagonally upward and downward. At this time, only the massage protrusion 210 of the massage roller 200 can contact the back to perform rolling massage, and the scrubbing bristles of the second surface 102 of the substrate 100 are away from the human back, thereby realizing the use of only its massage function.

[0043] In this embodiment, as Figures 1 to 5 As shown, the first surface 101 and / or the second surface 102 extend along their width direction to form a raised wall 130, and both sides of the through groove have raised walls 130. The two side walls of the through groove are provided with first mounting holes 131 corresponding to the positions of the raised walls 130. The massage roller 200 is pivotally connected to the accommodating space 110 by inserting the two ends of the first pivot shaft 220 into the first mounting holes 131 respectively. In this way, by designing the raised walls 130 to increase the wall thickness of the first mounting holes 131, the structural strength is improved without making the substrate 100 too thick or bulky, so as to ensure convenient and lightweight use and improve the reliability of the structural design.

[0044] Specifically, such as Figure 8 and Figure 9As shown, a first groove 132 is provided on one side of the substrate 100 corresponding to the position of the protruding wall 130. The first groove 132 communicates with the first mounting hole 131. The hub of the massage roller 200 is provided with a first through hole 230 along the axial direction. One end of the first pivot shaft 220 has a first fixing part 221, so that the first pivot shaft 220 passes through the first mounting hole 131 and the first through hole 230 and the first fixing part 221 is embedded in the first groove 132 for fixation, thereby pivotally connecting the massage roller 200 in the accommodating space 110.

[0045] Of course, it is understandable that in other embodiments, the first pivot shaft 220 and the hub of the massage roller 200 can be designed as an integral structure, and the protruding wall 130 of the base plate 100 can be designed as a flip-top fastener. In this way, during installation, the top cover of the protruding wall 130 can be opened first, and the first pivot shafts 220 on both sides of the hub of the massage roller 200 can be placed in the first mounting holes 131 respectively. Then, the installation is carried out by closing the top cover of the protruding wall 130. The first pivot shaft 220 can rotate in the first mounting hole 131. This implementation method can also realize the pivotal connection of the massage roller 200 in the accommodating space 110, and at the same time, it is included in the protection scope of this utility model.

[0046] In this embodiment, as Figure 8 and Figure 9 As shown, at least one end of the substrate 100 is provided with a connecting portion 140, and at least one of the connecting portions 140 of two adjacent substrates 100 is provided with a second mounting hole 141 along the width direction. The connecting portions 140 of multiple adjacent substrates 100 are connected to each other by means of a second pivot shaft 150 inserted into the second mounting hole 141. Preferably, two connecting portions 140 are used at each end of the substrate 100, and the two connecting portions 140 are spaced apart to improve the stability and reliability of the bending connection between adjacent substrates 100. The connecting portion 140 is axially shaped. The ends of the substrates 100 at both ends of the back-rubbing massage tool may not be provided with connecting portions 140, but it is preferable to provide a handle portion 20 at the ends of the substrates 100 at both ends so that the user can grasp the handle portion 20 and pull the back-rubbing massage tool to move it diagonally up and down. The structure and shape of the handle portion 20 can adopt the existing method, as long as it is easy for the hand to grasp.

[0047] Specifically, such as Figure 8 and Figure 9As shown, at least one side of the connecting portion 140 is provided with a second groove 142, which communicates with the second mounting hole 141. One end of the second pivot shaft 150 has a second fixing portion 151. The connecting portions 140 of two adjacent substrates 100 are provided with second mounting holes 141 along the width direction, so that the second pivot shaft 150 passes through the second mounting holes 141 of the two adjacent substrates 100 respectively, and the second fixing portion 151 is embedded in the second groove 142 to achieve a bendable connection. In this embodiment, as shown... Figure 6 and Figure 7 As shown, the substrate 100 adopts an integral molding structure. Two connecting portions 140 at one end of each substrate 100 are respectively provided in correspondence with two connecting portions 140 at one end of the adjacent substrate 100. A second pivot shaft 150 is simultaneously inserted into the second mounting holes 141 of the four connecting portions 140 between two adjacent substrates 100, thereby realizing a bendable connection between two adjacent substrates 100.

[0048] Of course, it is understood that in other embodiments, the second mounting hole 141 of the substrate 100 connecting portion 140 can also be installed by a flip-top cover. In this way, during installation, the top cover is first flipped open to open the second mounting hole 141. The second pivot shaft 150 can be integrally formed with the connecting portion 140 of one of the substrates 100. The second pivot shaft 150 is placed in the second mounting hole 141 of the connecting portion 140 of the other substrate 100. Then the top cover is closed for installation. The second pivot shaft 150 can rotate in the second mounting hole 141. This implementation can also achieve a bendable connection between two adjacent substrates 100, and it is also included in the protection scope of this utility model.

[0049] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0050] This utility model discloses a multifunctional back-rubbing massage tool, comprising multiple constituent units 10, which are rotatably connected to each other. Each constituent unit 10 includes a base plate 100 and at least one massage roller 200. The massage roller 200 has massage protrusions 210 on its outer periphery. The base plate 100 has opposing first surfaces 101 and second surfaces 102. The base plate 100 has an accommodating space 110, and the massage roller 200 is pivotally connected within the accommodating space 110. The massage protrusions 210 of the massage roller 200 protrude from the first surface 101 and / or the second surface 102. 01 and / or the second surface 102 are provided with a scrubbing part 120. Thus, by providing a massage roller 200 and a scrubbing part 120 on the substrate 100, the product has both back scrubbing and massage functions, thereby meeting the user's various functional needs. In use, the massage protrusions 210 of the massage roller 200 roll against the back for massage, and the scrubbing part 120 on the substrate 100 can contact and rub against the surface of the human skin to scrub the back.
