[0047] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any changes in mechanism, method, or function made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0048] The terms used herein, such as "upper", "lower", "left", "right", "front", "back", etc., which indicate relative spatial positions, are used for the purpose of convenience to describe the relationship between one feature and another feature as shown in the accompanying drawings. It is understood that, depending on the placement of the product, the terms of relative spatial positions may be intended to include different orientations other than those shown in the drawings, and should not be construed as limitations on the claims. In addition, the descriptor "horizontal" used herein is not completely equivalent to being perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0049] like Figure 1-4 shows a vibration capsule 100 of the first embodiment of the utility model, and the vibration capsule 100 includes a shell 10, a vibration element 20 located in the shell 10, a battery assembly 30 and a circuit board 40. The vibration element 20 and the battery assembly 30 are both electrically connected to the circuit board 40. The battery assembly 30 is used to supply power to the circuit board 40 and the vibration element 20, and the circuit board 40 is used to control the start and stop and working state of the vibration element 20. The vibration element 20 can generate vibration, and the vibration element 20 is tilted relative to the axis of the vibration capsule 100. In this way, the vibration element 20 can generate vibration in both the axial and radial directions of the vibration capsule 100, thereby realizing multi-dimensional vibration of the vibration capsule 100.

[0050] The vibrating capsule 100 also includes a fixing structure 50 for fixing the vibrating element 20 in the housing 10, and the fixing structure 50 is integrally formed with the housing 10. The vibration generated by the vibrating element 20 is transmitted to the housing 10 through the fixing structure 50, and the tilted setting of the vibrating element 20 causes the vibrating capsule 100 to vibrate in both the axial and radial directions. The fixing structure 50 is integrally formed with the housing 10, and the design of the motor bracket is omitted, so that the vibrating element 20 is fixed in the housing 10 through the fixing structure 50, which facilitates the assembly of the vibrating capsule 100.

[0051] The housing 10 is made of a biocompatible material and includes a first shell 11 and a second shell 12 joined to the first shell 11 along the axial direction of the vibrating capsule 100. The first shell 11 and the second shell 12 can be bonded together by glue or laser welded together, and the fixing structure 50 is specifically formed integrally with the first shell 11. For the convenience of description, it is defined herein that along the axial direction of the vibrating capsule 100, the position of the first shell 11 is below, and the direction toward the first shell 11 is downward, the position of the second shell 12 is above, and the direction toward the second shell 12 is upward.

[0052] In other embodiments of the present invention, the housing 10 may also adopt a three-section design, including a first shell and two second shells respectively connected to two ends of the first shell.

[0053] like Figure 3As shown in Figure 4, the fixing structure 50 specifically includes a first clamping wall 51 and a second clamping wall 52 spaced apart in the radial direction of the vibration capsule 100, at least one convex rib 53 disposed between the first clamping wall 51 and the second clamping wall 52, and a limiting groove 54 is provided on the convex rib 53. The vibration element 20 is clamped between the first clamping wall 51 and the second clamping wall 52, and the first clamping wall 51 and the second clamping wall 52 define the position of the vibration element 20 in the radial direction of the vibration capsule 100, and a part of the vibration element 20 is disposed in the limiting groove 54. The limiting groove 54 has a first side surface 541 extending along the tilting direction of the vibration element 20, and a second side surface 542 disposed on the side of the first side surface 541 away from the second shell 12 in the tilting direction. The first side surface 541 and the second side surface 542 are disposed at an angle, and the vibration element 20 is simultaneously attached to the first side surface 541 and the second side surface 542, so that the vibration element 20 remains tilted in the housing 10.

[0054] Furthermore, glue may be used to bond the vibration element 20 and the fixing structure 50 to ensure that the vibration element 20 can be firmly fixed in the housing 10 .

[0055] In this embodiment, the vibration element 20 is a flat motor, which generates vibration through the rotation of the eccentric wheel inside the flat motor. Figure 1 As shown in FIG. 2 , the flat motor specifically includes a motor body 211, a connecting portion 212 disposed on one side of the motor body 211 in the radial direction, and a wire extending from the connecting portion 212. The motor body 211 is roughly disc-shaped. The above-mentioned tilting direction is consistent with the radial direction of the motor body 211. The motor body 211 is clamped between the first clamping wall 51 and the second clamping wall 52, and a part of the area is disposed in the limiting groove 54.

[0056] In this embodiment, the connection portion 212 is specifically arranged obliquely downward, the first side surface 541 abuts against the bottom surface of the motor body 211, and the first side surface 541 is a plane so as to be able to fit with the bottom surface of the motor body 211, and the second side surface 542 abuts against the side of the motor body 211 on which the connection portion 212 is arranged in the oblique direction, and the motor body 211 is specifically in contact with the second side surface 542 through its periphery, so the second side surface 542 is an arc surface so as to be able to fit with the periphery of the motor body 211. The motor body 211 is arranged in the limiting groove 54 in this way, which can ensure that the flat motor is fixed in the housing 10 in the form of the connection portion 212 being arranged obliquely downward.

[0057] Furthermore, the rib 53 includes a first rib 531 and a second rib 532 spaced apart in the radial direction of the vibration capsule 100 , and the connecting portion 212 is clamped between the first rib 531 and the second rib 532 , further fixing the flat motor in the housing 10 .

[0058] In this embodiment, the first card wall 51 and the second card wall 52 both extend to the top of the vibration element 20, the battery assembly 30 is located above the vibration element 20, and the battery assembly 30 abuts against the first card wall 51 and the second card wall 52 in the axial direction of the vibration capsule 100, so that the first card wall 51 and the second card wall 52 can define the position of the battery assembly 30 in the axial direction of the vibration capsule 100. The inner wall of the housing 10 defines the position of the battery assembly 30 in the radial direction of the vibration capsule 100. The circuit board 40 is located above the battery assembly 30 and is electrically connected to the battery assembly 30, that is, the circuit board 40 is fixed in the housing 10 through the battery assembly 30.

[0059] Continue with reference Figure 5 As shown in Figure 7, the battery assembly 30 includes a battery cell for outputting voltage, a positive electrode connecting piece 33 connected to the positive electrode of the battery cell, and a negative electrode connecting piece 34 connected to the negative electrode of the battery cell. The circuit board 40 is provided with a first welding hole 41 and a second welding hole 42. The positive electrode connecting piece 33 extends into the first welding hole 41 and is welded to the circuit board 40, and the negative electrode connecting piece 34 extends into the second welding hole 42 and is welded to the circuit board 40. In this way, the battery assembly 30 is electrically connected to the circuit board 40, and the circuit board 40 is fixed above the battery assembly 30 through the connecting piece and the welding hole. The positive electrode connecting piece 33 and the negative electrode connecting piece 34 are preferably connected to the battery cell by welding, so that the various components of the battery assembly 30 are connected as a whole, so that the battery assembly 30 can be installed in the housing 10 as a whole.

[0060] As a preferred solution of this embodiment, Figure 5 As shown, the battery assembly 30 includes a battery unit, a positive electrode connecting piece 33, a negative electrode connecting piece 34 and an intermediate electrode connecting piece 35 connected to the battery unit. The battery unit includes two batteries, namely, a first battery 31 and a second battery 32. The positive electrode connecting piece 33 is connected to the positive electrode of the battery unit, the negative electrode connecting piece 34 is connected to the negative electrode of the battery unit, and the intermediate electrode connecting piece 35 is connected to the negative electrode of the first battery 31 and the positive electrode of the second battery 32 at the same time. For a battery unit consisting of two batteries, the positive electrode of the first battery 31 is the positive electrode of the battery unit, the negative electrode of the second battery 32 is the negative electrode of the battery unit, the positive electrode connecting piece 33 is connected to the positive electrode of the first battery 31, and the negative electrode connecting piece 34 is connected to the negative electrode of the second battery 32.

[0061] Specifically, one end of the positive electrode connecting piece 33 is welded to the positive electrode of the first battery 31, one end of the negative electrode connecting piece 34 is welded to the negative electrode of the second battery 32, and both ends of the intermediate electrode connecting piece 35 are respectively welded to the negative electrode of the first battery 31 and the positive electrode of the second battery 32, so that the components of the battery assembly 30 are connected as a whole. The other end of the positive electrode connecting piece 33 of the assembled battery assembly 30 is welded to the first welding hole 41, and the other end of the negative electrode connecting piece 34 is welded to the second welding hole 42, so as to connect the battery assembly 30 with the circuit board 40.

[0062] In the battery assembly 30, the voltage of one battery can be output through one of the positive electrode connecting sheet 33 and the negative electrode connecting sheet 34 and the intermediate electrode connecting sheet 35, and the voltage of two batteries can be output through the positive electrode connecting sheet 33 and the negative electrode connecting sheet 34. In this way, the battery assembly 30 can supply power to the vibration elements 20 of different voltages.

[0063] The vibration element 20 (a flat motor in this embodiment) is also provided with two wires. If the working voltage of the vibration element 20 is the voltage of one battery, the two wires are respectively electrically connected to one end of the intermediate pole connecting piece 35 and the first welding hole 41 or the second welding hole 42 on the circuit board 40; if the working voltage of the vibration element 20 is the voltage of two batteries, the two wires are respectively electrically connected to the first welding hole 41 and the second welding hole 42 on the circuit board 40. The connection between the wires and the battery assembly 30 and the circuit board 40 is a welding connection. The circuit board 40 integrates multiple electronic components to form a circuit to control the start and stop and working state of the vibration element 20.

[0064] In other embodiments of the present invention, if the working voltage of the vibration element 20 is the voltage of a battery, such as Figure 6 As shown, the battery assembly 30 includes a battery unit, a positive electrode connecting piece 33 and a negative electrode connecting piece 34 connected to the battery unit, and the battery unit only includes a first battery 31. At this time, the positive electrode connecting piece 33 is connected to the positive electrode of the first battery 31, the negative electrode connecting piece 34 is connected to the negative electrode of the first battery 31, and the two wires of the vibration element 20 are respectively electrically connected to the first welding hole 41 and the second welding hole 42 on the circuit board 40. It can be imagined that according to the above-mentioned setting method of the battery assembly 30, it can also be deduced that the battery assembly 30 includes three or even more than three batteries.

[0065] In this embodiment, combined with Figure 1-2, the vibration element 20 is located in the first shell 11, the battery assembly 30 is at least partially located in the first shell 11, and as mentioned above, the circuit board 40 is electrically connected to the battery assembly 30. Therefore, when assembling the vibration capsule 100, the vibration element 20 motor can be first installed in the first shell 11, and then the assembly of the battery assembly 30 and the circuit board 40 can be installed in the first shell 11, and finally the second shell 12 is joined to the first shell 11. In this embodiment, the battery assembly 30 is entirely located in the first shell 11. In other embodiments, the battery assembly 30 can also be partially disposed beyond the first shell 11, as long as the inner wall of the first shell 11 can limit the position of the battery assembly 30 in the radial direction of the vibration capsule 100.

[0066] Combination Figure 4 As shown, a groove 111 is formed on the inner wall of the first shell 11, and the groove 111 extends to the opening of the first shell 11 along the axial direction of the vibration capsule 100, and the wire can be arranged in the groove 111 and extend to the opening of the first shell 11 to connect with the circuit board 40 or the middle pole connecting piece 35. In other embodiments of the utility model, a dedicated card slot can also be provided in the shell 10 to fix the wire.

[0067] Considering that the vibration capsule 100 needs to be swallowed into the human body for use, from the perspective of facilitating swallowing by the human body, the length of the shell 10 is 10 mm to 30 mm, and the diameter is 6 mm to 15 mm.

[0068] The first battery 31 and the second battery 32 are large-capacity button batteries, each of which has a diameter of 5.8 mm to 11.6 mm and a height of 2.1 mm to 5.4 mm. Preferably, button batteries with a diameter of 9.5 mm and a height of 2.1 mm or a diameter of 9.5 mm and a height of 2.7 mm are used.

[0069] The flat motor is a standard part on the market, with a diameter ranging from 4mm to 12mm and a thickness ranging from 1.5mm to 5mm. Preferably, a flat motor with a diameter of 8mm or 10mm and a thickness of 2mm to 4mm is used.

[0070] The periphery of the circuit board 40 is preferably configured to extend in an arc shape to match the shape of the housing 10. The thickness of the circuit board 40 is 0.2 mm to 1 mm, preferably designed to be 0.35 mm or 0.5 mm. The height of the circuit board 40 is less than 2 mm, preferably designed to be less than 1.5 mm.

[0071] In this embodiment, the second shell 12 is transparent, and the vibration capsule 100 further includes an inner cover 13 disposed inside the second shell 12 . Multiple vibration capsules 100 can be distinguished by the different colors of their inner covers 13 .

[0072] like Figure 8 -11 shows the vibration capsule 100 of the second embodiment of the utility model. The difference between the second embodiment and the first embodiment is that: in the second embodiment, the connection part 212 is specifically arranged obliquely upward, and at this time, the first side surface 541 abuts against the bottom surface of the motor body 211, and the second side surface 542 abuts against the side of the motor body 211 away from the connection part 212 in the oblique direction. Similar to the first embodiment, the first side surface 541 is a plane so as to be able to fit with the bottom surface of the motor body 211, and the motor body 211 is specifically in contact with the second side surface 542 through its outer periphery, so the second side surface 542 is an arc surface so as to be able to fit with the outer periphery of the motor body 211. Such an arrangement can ensure that the flat motor is stably fixed in the housing 10 in the form of the connection part 212 being arranged obliquely upward.

[0073] like Fig.12 -15 shows the vibration capsule 100 of the third embodiment of the utility model. The difference between the third embodiment and the first embodiment is that: in the third embodiment, the vibration element 20 is an eccentric motor, which includes a motor body 221, an eccentric wheel 222 located on one side of the axial direction of the motor body 221, and a wire extending from the motor body 221. The motor body 221 is roughly cylindrical, and the tilting direction is consistent with the axial direction of the motor body 221. When the eccentric motor is started, the eccentric wheel 222 rotates to generate vibration. The motor body 221 is clamped between the first clamping wall 51 and the second clamping wall 52, and part of the area is set in the limiting groove 54. In the third embodiment, three convex ribs 53 are specifically provided, and the three convex ribs 53 are arranged along the radial direction of the vibration capsule 100. The limiting grooves 54 on the three convex ribs 53 all accommodate part of the motor body 221.

[0074] The motor body 221 is disposed to one side in the radial direction of the vibrating capsule 100 so that the eccentric wheel 222 will not interfere with the housing 10 when rotating.

[0075] In the third embodiment, the eccentric wheel 222 is specifically arranged obliquely downward, the first side surface 541 abuts against the outer periphery of the motor body 221, and the second side surface 542 abuts against the side of the motor body 221 close to the eccentric wheel 222 in the oblique direction. The first side surface 541 is specifically an arc surface so as to be able to fit with the outer periphery of the motor body 221, and the second side surface 542 is specifically a plane so as to be able to fit with the side of the motor body 221 close to the eccentric wheel 222 in the oblique direction. Such an arrangement can ensure that the eccentric wheel motor is stably fixed in the housing 10 in the form of the eccentric wheel 222 being arranged obliquely downward.

[0076] The eccentric motor is a standard part on the market, with a diameter range of 4mm to 12mm and a height range of 6mm to 18mm. Preferably, an eccentric motor with a diameter of 4mm, 6mm and 8mm and a height of 8mm to 15mm is used.

[0077] like Fig.16 -19 shows a vibration capsule 100 of the fourth embodiment of the utility model. The difference between the fourth embodiment and the third embodiment is that, in the fourth embodiment, the eccentric wheel 222 is specifically arranged obliquely upward, the first side surface 541 abuts against the outer periphery of the motor body 221, and the second side surface 542 abuts against the side of the motor body 221 away from the eccentric wheel 222 in the said oblique direction. Similar to the third embodiment, the first side surface 541 is specifically an arc surface so as to be able to fit with the outer periphery of the motor body 221, and the second side surface 542 is specifically a plane so as to be able to fit with the side of the motor body 221 away from the eccentric wheel 222 in the said oblique direction. Such an arrangement can ensure that the eccentric wheel motor is stably fixed in the housing 10 in the form of the eccentric wheel 222 being arranged obliquely upward.

[0078] In other embodiments of the present invention, the vibration element 20 may also be a linear motor.

[0079] The assembly method of the vibration capsule 100 provided by the utility model comprises:

[0082] In step S3, the assembled battery assembly 30 and circuit board 40 are installed into the first shell 11, bonded to the first shell 11 by glue, and the wires of the vibration element 20 are connected to the circuit board 40 by welding, so that the vibration element 20, the battery assembly 30 and the circuit board 40 are electrically connected.

[0083] Step S4 , installing the inner cover 13 and the second shell 12 , and respectively joining the inner cover 13 and the second shell 12 to the first shell 11 , thereby completing the assembly of the vibration capsule 100 .

[0084] Compared with the solution of designing the motor bracket separately, the assembly of the vibration capsule requires first installing the vibration element and the motor bracket together, and then assembling it together with the battery assembly and the circuit board into the core structure, and then installing the assembled core structure into the shell. This requires ensuring the compactness and coaxiality of each component of the core structure, and has high assembly requirements. The vibration capsule provided in this application reduces the structural components, while reducing the manufacturing cost and assembly difficulty.

[0085] To sum up, the vibration capsule 100 proposed in the utility model, on the basis of being able to realize multi-dimensional vibration, integrates the fixing structure 50 and the shell 10 into one piece, and there is no need to design a separate motor bracket, thereby reducing the manufacturing cost of the vibration capsule 100. The vibration element 20, the battery assembly 30, and the circuit board 40 can be separately installed in the shell 10 for fixation, thereby reducing the installation process and the difficulty of assembly.
