The air extraction member is used to extract air from the cupping tank body to form a negative pressure inside the cupping tank body. The cupping tank body is used to adsorb on the skin surface by using the negative pressure for cupping. During the actual cupping process, essential oils are usually applied to the human skin surface to facilitate operations such as cupping and relieve skin pain. However, this will also cause substances such as essential oils or hairs to be sucked into the trachea and the air extraction member during air extraction, resulting in problems such as dirt or blockage inside the air extraction member and the trachea.

[0040] Some embodiments of the present application disclose a cupping device assembly and a cupping device thereof. The aim is to solve the problems that the air extraction member of the traditional cupping device and its cupping device are prone to dirt and blockage, so as to better ensure the hygiene and safety of the product.

[0041] The cupping device assembly and the cupping device thereof will be introduced in detail through specific embodiments below.

[0042] Embodiment 1

[0043] This embodiment discloses a cupping device assembly and a cupping device thereof.

[0044] Please refer to Figure 1 , Figure 1 which shows the cupping device assembly described in the first embodiment of the present application.

[0045] The cupping device assembly includes a cupping device and one or more cupping cans 8.

[0046] The cupping can 8 can be set as a cover structure with an open bottom and an interface provided at the top as shown in Figure 1 . Of course, it can be understood that the interface position of the cupping can 8 is not limited to the top. In other embodiments, the interface of the cupping can 8 can be provided at the side of the cupping can 8 and other positions. When performing moving cupping, the bottom of the cupping can 8 is abutted against the skin to use the skin to seal the open bottom area of the cupping can 8, so that the cupping can 8 and the skin enclose a substantially airtight chamber. The air in the chamber is extracted through the interface of the cupping can 8 to form a negative pressure in the chamber, and the cupping can 8 firmly adheres to the skin surface by using the negative pressure for moving cupping physiotherapy.

[0047] Optionally, the cupping can 8 can be specifically set as a hollow cylindrical shape with a slightly wider bottom and gradually converging and narrowing upwards. Of course, the present application is not limited thereto. In other embodiments, the cupping can 8 can also be set as a gourd shape, a conical shape, a spherical shape, etc. according to requirements.

[0048] The number of the cupping cans 8 of the cupping device assembly can be specifically as shown in Figure 1The number of cupping cans 8 of the cupping device assembly is configured to be 4. Of course, it can be understood that the number of cupping cans 8 of the cupping device assembly is not limited by this example. In other embodiments, the number of cupping cans 8 of the cupping device assembly can also be configured to be 1, 2, 3, 5, 6 or even more according to requirements.

[0049] As Figure 1 shown, the cupping device has a box body 1, and a storage part is arranged in the box body 1. The storage part includes, for example, a storage bin 117 for accommodating the cupping can 8. In this way, when the cupping device is not in use, the cupping can 8 can be stored in the storage bin 117, which is more conducive to the neatness of the product and the dust prevention of the cupping can 8.

[0050] Optionally, as Figure 1 shown, 4 storage bins 117 can be arranged on the box body 1 of the cupping device for accommodating 4 cupping cans 8 one by one. The storage bin 117 can be arranged in a shape that is roughly adapted to the outer shape of the cupping can 8 to avoid waste of space. Of course, the present application is not limited to this. In other embodiments, 1 storage bin 117 can also be arranged to accommodate 4 cupping cans 8, or 2 storage bins 117 can be arranged so that each storage bin 117 accommodates 2 cupping cans 8.

[0051] The cupping device specifically includes a box body 1, an air extraction member 2, a liquid collection bottle 3, a filter member 4, etc.

[0052] The air extraction member 2 is arranged in the box body 1; the liquid collection bottle 3 is detachably assembled on the box body 1. The liquid collection bottle 3 is provided with an air inlet joint 36 and an exhaust joint 32. The exhaust joint 32 is communicated with the air extraction member 2, and the air inlet joint 36 is used for communicating with the cupping can 8; the filter member 4 is arranged in the liquid collection bottle 3, and the filter member 4 is used for filtering out the oil liquid in the gas. The liquid collection bottle 3 is used for collecting and storing the oil liquid filtered out by the filter member 4.

[0053] Of course, it can be understood that in actual use scenarios, the composition of the substances filtered by the filter member 4 can be diversified and is not limited to the listed oil liquid. In fact, it can also be replaced by a combination of one or more of oil liquid (such as essential oil, body surface oil, etc.), human hair, and body surface dirt.

[0054] By providing a liquid collecting bottle 3 between the air extraction member 2 and the cupping jar body 8. Specifically, the air extraction member 2 is communicated with the exhaust joint 32 of the liquid collecting bottle 3, and the cupping jar body 8 is communicated with the intake joint 36 of the liquid collecting bottle 3. When the air extraction member 2 extracts air, the gas in the cupping jar body 8 enters the liquid collecting bottle 3 along the intake joint 36, discharges from the liquid collecting bottle 3 along the exhaust joint 32, and then enters the air extraction member 2. Among them, the liquid collecting bottle 3 is connected with a filtering member 4. The liquid collecting bottle 3 uses the filtering member 4 to filter out substances such as oil in the gas, which can prevent substances such as oil from entering the air extraction member 2, thereby solving problems such as dirt or blockage caused by substances such as oil entering the air extraction member 2. The filtered substances such as oil are stored in the liquid collecting bottle 3. Since the liquid collecting bottle 3 is detachably connected to the box body 1, the liquid collecting bottle 3 can be conveniently removed from the box body 1 for pouring out the oil and cleaning or replacing the liquid collecting bottle 3, preventing secondary pollution of the air extraction member 2 caused by the long-term storage of the oil in the liquid collecting bottle 3, and thus better ensuring the hygienic safety of the product.

[0055] Please refer to Figure 2 , Figure 2 which shows the sectional structure of the box body 1.

[0056] The box body 1 includes an inner shell 11, an outer shell 12 and a face shell 13. The inner shell 11 is accommodated in the outer shell 12 and is provided on the top of the outer shell 12 and the inner shell 11 to block the gap between the top of the outer shell 12 and the top of the inner shell 11. An installation chamber is formed between the outer shell 12 and the inner shell 11, and the installation chamber is used to accommodate components such as the air extraction member 2, throttle valve, solenoid valve 7, multi-way joint 5 of the cupping device. A receiving chamber 117 with an opening is recessed on the inner shell 11. A control panel 131 for controlling the cupping device is provided on the face shell 13. The control panel 131 is located on one side of the opening of the receiving chamber 117 or around the opening of the receiving chamber 117.

[0057] In order to facilitate the storage and loading and unloading between the liquid collecting bottle 3 and the box body 1, the storage part of the cupping device also includes an assembly groove 111 for detachably connecting and assembling the liquid collecting bottle 3. Specifically, the assembly groove 111 is provided on the box body 1, and the box body 1 is also provided with a first joint 114 exposed in the assembly groove 111, and the first joint 114 is connected to the exhaust member 2 in the installation chamber; the liquid collecting bottle 3 is detachably assembled in the assembly groove 111, and the exhaust joint 32 is connected to the first joint 114 when the liquid collecting bottle 3 is assembled in the assembly groove 111, and the exhaust joint 32 is separated from the first joint 114 when the liquid collecting bottle 3 is removed from the assembly groove 111. In this way, when the cupping operation or daily storage is required, the liquid collecting bottle 3 can be assembled in the assembly groove 111. When the liquid collecting bottle 3 is assembled in the assembly groove 111, the exhaust joint 32 of the liquid collecting bottle 3 is connected to the first joint 114 to achieve the communication between the liquid collecting bottle 3 and the air extraction member 2, which can facilitate the air extraction member 2 to exhaust the cupping body 8, and the liquid collecting bottle 3 can filter out the oil and other substances in the gas through the filter 4 to avoid contaminating the air extraction member 2. When the liquid collecting bottle 3 needs to be de-oiled, cleaned or replaced, the liquid collecting bottle 3 can be taken out from the assembly groove 111, which is convenient to use.

[0058] Alternatively, if Figure 1 As shown, the air inlet connector 36 of the liquid collecting bottle 3 and the cupping body 8 can be connected via a first air pipe 91. The first air pipe 91 can be a hose, for example, a rubber hose, a silicone hose, etc.

[0059] Optionally, the first air pipe 91 can be configured as follows Figure 1 In the one-in-one-out two-end structure shown, the inlet of the first air pipe 91 is connected to the interface of the cupping body 8, and the outlet of the first air pipe 91 is connected to the first joint 114, so that the suction member 2 draws negative pressure for one cupping body 8 at a time. Of course, in other embodiments, the first air pipe 91 can also be set as a multi-inlet and one-out multi-end structure, each inlet of the first air pipe 91 is used to correspond to the interface of a cupping body 8, and the outlet of the first air pipe 91 is used to connect the first joint 114, so that the suction member 2 draws negative pressure for multiple cupping bodies 8 at the same time.

[0060] The assembly groove 111 is also used to accommodate the first air pipe 91, for example, Figure 1 As shown, the volume of the liquid collecting bottle 3 is smaller than the volume of the assembly groove 111. When the liquid collecting bottle 3 is assembled in the assembly groove 111, a certain gap is formed between the liquid collecting bottle 3 and the assembly groove 111, and the first air pipe 91 can be assembled in the gap, so that the product is more regular when stored, and the user experience is better. Further, when the liquid collecting bottle 3 is assembled in the assembly groove 111, the liquid collecting bottle 3 is located at one end in the assembly groove 111, and a vacant space is formed at the other end of the assembly groove 111, and the first air pipe 91 can be accommodated in the other end of the assembly groove 111.

[0061] To give a more detailed example, the assembly groove 111 is set as a rectangular groove, and the liquid collecting bottle 3 is set as a rectangular bottle or a square bottle with a width equivalent to that of the assembly groove 111. When the liquid collecting bottle 3 is assembled in the assembly groove 111, the liquid collecting bottle 3 is located at one end of the length direction of the assembly groove 111 and roughly fills the space at one end of the length direction of the assembly groove 111, thereby realizing the assembly of the liquid collecting bottle 3 in the assembly groove 111 with three-sided contact or three-sided small gaps 41. The length of the assembly groove 111 is greater than that of the liquid collecting bottle 3, and the other end of the length direction of the assembly groove 111 is not filled by the oil collecting groove, thereby forming a vacant space for accommodating the first air pipe 91.

[0062] Of course, the shape of the assembly groove 111 is not limited to the rectangle shown in the figure. In fact, the assembly groove 111 can be set to any shape according to the requirements, such as a circle, an ellipse, a polygon, etc. The assembly groove 111 is also not limited to being configured to be used to simultaneously store the liquid collection bottle 3 and the first air tube 91. In other embodiments, an air tube warehouse can also be provided on the box body 1 to separately store the first air tube 91, so as to realize the independent and separate storage of the liquid collection bottle 3 and the first air tube 91.

[0063] Please continue to see Figure 2 The side wall at one end of the assembly groove 111 is provided with a step portion 112 protruding relative to the inner bottom surface of the assembly groove 111, and a first joint 114 is provided on the side of the step portion 112 facing the assembly groove 111, and a side of the step portion 112 facing away from the assembly groove 111 is recessed to form a gap 113, and a second joint 115 connected to the first joint 114 is provided in the gap 113, and the second joint 115 is connected to the second air pipe 92 (such as Figure 8 A step portion 112 is provided on the side wall at one end of the assembly groove 111, and the step portion 112 raises the distance between the step portion 112 and the housing 12, thereby forming a larger space for avoiding a gap 113, thereby reserving enough space for the second joint 115 to be connected to the second air pipe 92, and the second air pipe 92 also has more sufficient space to extend downward, which can reduce the folding and bending of the second air pipe 92, so that the air extraction efficiency of the air extraction member 2 on the cupping body 8 is higher.

[0064] Combination Figure 3 , Figure 4 and Figure 5 It can be understood that the exhaust connector 32 is arranged on the side of the liquid collecting bottle 3 and protrudes laterally relative to the side surface of the liquid collecting bottle 3. When the liquid collecting bottle 3 is assembled in the assembly groove 111, the exhaust connector 32 rests on the step portion 112 and is correspondingly connected to the first connector 114 on the step portion 112. In this way, while avoiding air at the second air pipe 92 to reduce the folding of the second air pipe 92, the space above the step portion 112 in the assembly groove 111 is more fully utilized to accommodate the exhaust connector 32 of the liquid collecting bottle 3, so that the assembly of the liquid collecting bottle 3 and the assembly groove 111 is more compact.

[0065] As Figure 2 shown, the first joint 114 may specifically be an insertion tube protruding from the outer surface of the stepped portion 112, and the exhaust joint 32 is correspondingly a socket adapted to receive the first joint 114 inside the exhaust joint 32. In this way, while ensuring the repeated disassembly and assembly of the first joint 114 and the exhaust joint 32, better connection sealing performance can be obtained, thus ensuring the air extraction efficiency. Of course, vice versa, the exhaust joint 32 may be provided as an insertion tube protruding downward from the side of the liquid collection bottle 3, and the first joint 114 may be provided as a socket provided in the stepped portion 112 and adapted to receive the exhaust joint 32 therein.

[0066] Optionally, in combination with Figure 3 and Figure 4 and Figure 5 it can be understood that a positioning protrusion 116 is provided on one of the bottom of the liquid collection bottle 3 and the inner bottom surface of the assembly groove 111, and a groove 311 is provided on the other. When the liquid collection bottle 3 is assembled in the assembly groove 111, the positioning protrusion 116 extends into the groove 311. In this way, the positioning and assembly of the liquid collection bottle 3 in the assembly groove 111 are more accurate. At the same time, the convenience of the loading and unloading operation of the liquid collection bottle 3 in the assembly groove 111 can be well considered. The liquid collection bottle 3 can be pulled out from the assembly groove 111, so as to conveniently take out the liquid collection bottle 3 for operations such as pouring out oil or cleaning the liquid collection bottle 3.

[0067] Please refer to Figure 3 , Figure 3 which shows the cross-sectional structure of the liquid collection bottle 3.

[0068] To facilitate the user to clean, pour oil or replace the filter element 4 of the liquid collection bottle 3, as Figure 3 shown, the liquid collection bottle 3 includes a bottle body 31 and a cover body 33. The cover body 33 is detachably covered on the bottle body 31, so that the cover body 33 and the bottle body 31 enclose a liquid collection cavity 35. The air inlet joint 36 is provided on the cover body 33 or the bottle body 31 and is communicated with the liquid collection cavity 35. The exhaust joint 32 is provided on the cover body 33 or the bottle body 31 and is communicated with the liquid collection cavity 35. The filter element 4 is provided on the cover body 33 and faces the inside of the liquid collection cavity 35. The gas in the liquid collection cavity 35 is filtered by the filter element 4 and then discharged along the exhaust joint 32. In this way, the filter element can be located at the upper part of the liquid collection bottle 3, avoiding the filter element directly contacting the essential oil falling on the lower part of the liquid collection bottle 3. Moreover, the user can conveniently pour out substances such as essential oil in the bottle body 31, clean the bottle body 31 or replace the filter element 4 and other operations by opening the bottle cap, which is convenient to use.

[0069] Among them, as Figure 4 and Figure 5As shown, the bottle body 31 is detachably assembled on the box body 1. Specifically, the bottle body 31 is detachably received in the assembly groove 111 of the box body 1. A groove 311 is provided at the bottom of the bottle body 31, and the positioning protrusion 116 on the inner bottom surface of the assembly groove 111 is received by the groove 311, so as to realize the positioning and stability of the bottle body 31 in the assembly groove 111. And by arranging the groove 311 on the bottle body 31, it is more conducive to the bottle body 31 to stand after being taken out of the assembly groove 111, making it more convenient to use.

[0070] Optionally, in combination with Figure 3 、 Figure 5 It can be understood that a convex column 331 extending from the cover body 33 into the liquid collection cavity 35 is provided on the cover body 33. The convex column 331 can be configured to have a hollow internal structure, which is conducive to reducing the weight of the product and improving the molding quality of the product.

[0071] A locking member 42 is connected to the end of the convex column 331 away from the cover body 33. The locking member 42 can be, for example, a screw. Specifically, the screw is driven into the end of the hollow convex column 331 away from the cover body 33, so that the screw is detachably connected to the convex column 331.

[0072] In combination with Figure 6 It can be understood that the filter element 4 is configured in a ring shape. The filter element 4 is sleeved on the outside of the convex column 331. The locking member 42 blocks one end of the filter element 4 away from the cover body 33 and axially limits the filter element 4 between the cover body 33 and the locking member 42. The filter element 4 is radially spaced from the convex column 331 to define a gap 41 therebetween. The gap 41 is communicated with the exhaust joint 32. In this way, one axial end of the gap 41 between the convex column 331 and the filter ring is closed by the locking member 42, and the other axial end of the gap 41 between the convex column 331 and the filter ring is communicated with the exhaust joint 32. The gas in the liquid collection bottle 3 can pass through the filter element 4 and enter the gap 41 between the filter element 4 and the convex column 331, and then be discharged from the liquid collection bottle 3 along the exhaust joint 32 from the gap 41. Substances such as essential oils filtered out by the filter element 4 in the liquid collection bottle 3 drip and remain in the bottle body 31 because they cannot pass through the filter element 4. By using the annular filter element 4 and arranging it in a suspended manner in the liquid collection cavity 35, the gas can enter the gap 41 from the periphery of the annular filter element 4, filtering more gas at one time, ensuring the gas flow rate, effectively reducing the influence on the gas flow rate and flow rate, and improving the air extraction efficiency. And the annular filter element 4 can achieve a larger filter area, making the service life of the filter element 4 longer.

[0073] Since the filter element 4 is connected to the cover body and the filter element 4 is located at the upper part of the liquid collection bottle, a larger space for storing essential oils is ensured at the lower part of the liquid collection bottle, which can reduce the frequency of pouring oil for cleaning and simplify the user operation.

[0074] Optionally, as Figure 5As shown, a retaining wall 334 is provided on the cover body 33 beside the convex column 331. The retaining wall 334 is used to radially limit and clamp one end of the filter element 4 away from the locking member 42, thereby positioning the filter element 4 relative to the convex column 331. In this way, it is easier to ensure the uniformity of the circumferential gap 41 between the filter element 4 and the convex column 331, avoid loss of the filtering area, and better ensure the smoothness of the air flow at the filter element 4, improving the air extraction efficiency.

[0075] Optionally, the convex column 331 is cylindrical and the filter element 4 is annular. An annular gap 41 is formed between the filter element 4 and the convex column 331. In this way, the air intake uniformity at all circumferential positions of the filter element 4 is good. Of course, the shapes of the convex column 331 and the filter element 4 are not limited to the exemplified cylindrical and annular shapes, and the positioning and limiting structure of the filter element 4 is not limited to the retaining wall 334 either. In other embodiments, the limiting of the filter element 4 and the maintenance of the gap 41 can also be achieved by using the shape design of the convex column 331 and the filter element 4. For example, in some embodiments, the convex column 331 can also be set as a polygon, and the filter element 4 is annular or elliptical, etc. The convex column 331 is inscribed in the filter element 4, so that the inflection point positions of the polygonal convex column 331 support and position the filter element 4, and a gap 41 is formed between the position of the side of the convex column 331 and the filter element 4.

[0076] Optionally, the material of the filter element 4 can be filter cotton or filter net. The filter cotton can be fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, activated carbon filter cotton, etc. The filter net can be non-woven fabric, fiber net, activated carbon filter net, etc.

[0077] To facilitate the loading and unloading between the bottle body 31 and the cover body 33, and to ensure the stable and reliable connection between the bottle body 31 and the cover body 33 during assembly, a barrel plug 333 is provided at the bottom of the cover body 33, and a bottle mouth is provided at the top of the bottle body 31. When the cover body 33 is closed on the bottle body 31, the barrel plug 333 is inserted into the bottle mouth, thereby realizing the quick plug-in assembly between the bottle cap and the bottle body 31, with simple and easy installation.

[0078] The exhaust joint 32 is provided on the side of the bottle body 31 and protrudes laterally relative to the side surface of the bottle body 31. The cover body 33 is provided with a cover-side convex part 34 protruding laterally. The cover-side convex part 34 is detachably covered on the exhaust joint 32. A channel 342 is provided on the cover-side convex part 34. One end of the channel 342 is communicated with the exhaust joint 32, and the other end of the channel 342 is communicated with the liquid collection cavity 35 and is spaced from the liquid collection cavity 35 by the filter element 4; a clamping structure is provided between the cover-side convex part 34 and the exhaust joint 32. By using the clamping structure, further clamping and locking between the bottle body 31 and the bottle cap are realized, thereby better ensuring the firm connection between the bottle cap and the bottle body 31, and at the same time, also ensuring the disassembly convenience between the bottle cap and the bottle body 31.

[0079] More specifically, for example Figure 5 As shown, an air inlet joint 36, a convex column 331, a baffle 334 and an exhaust port 332 are provided at a position on the bottle cap corresponding to the inside of the cylinder plug 333. The cylinder plug 333 is of an annular structure. The convex column 331 passes through the cylinder plug 333. The baffle 334 is located on the side of the convex column 331 radially opposite to the cylinder plug 333, so that the annular filter element 4 is radially clamped between the cylinder plug 333 and the baffle 334 and nested outside the convex column 331. The exhaust port 332 is provided at a position corresponding to the gap 41 between the convex column 331 and the filter element 4, so as to communicate with the gap 41. The air inlet joint 36 may specifically be an insertion tube protruding opposite to the liquid collecting cavity 35, so as to facilitate the insertion connection between the first air tube 91 and the air inlet joint 36, thereby realizing the connection and conduction between the air inlet joint 36 and the cupping jar body 8.

[0080] One end of the channel 342 extends to the air inlet and communicates with the air inlet. The other end of the channel 342 forms a pipe joint protruding laterally. The liquid collecting bottle 3 further includes a 90° adapter 37. The adapter 37 is provided on the cover body 33 or on the bottle body 31. One end of the adapter 37 is connected to the other end of the channel 342 (i.e., the pipe joint). The other end of the adapter 37 is arranged downward and faces the exhaust joint 32. The other end of the adapter 37 is used to communicate with the first joint 114 when the exhaust joint 32 is connected to the first joint 114. For example, the other end of the adapter 37 is used to accommodate and pass through the first joint 114 passing through the exhaust joint 32, thereby realizing communication with the first joint 114.

[0081] In this way, the bottle body 31 is below the filter element 4, or the filter element 4 is in the upper part of the bottle body 31, that is, at the bottle mouth position. The convex column 331 is provided on the cover body 33. The filter element 4 is sleeved on the outer periphery of the convex column 331. The filter element 4 is detachably locked on the convex column 331 through the locking member 42, so as to facilitate the loading and unloading of the filter element 4. The lower end of the filter element 4 is blocked by the locking member 42. The upper end of the gap 41 between the filter element 4 and the convex column 331 is communicated with the channel 342 and the exhaust joint 32 through the exhaust port 332. The gas in the liquid collecting bottle 3 enters the gap 41 from the side of the filter element 4. After the filtered clean gas comes out from the upper end of the gap 41, it enters the exhaust port 332, the channel 342 and the exhaust joint 32 on the cover body 33 to discharge the liquid collecting bottle 3. The gas discharged from the liquid collecting bottle 3 enters the air extraction member 2 along the first joint 114, the second joint 115 and the second air tube 92 and is discharged from the other end of the air extraction member 2, for example, discharged to the external environment.

[0082] For example Figure 6 and Figure 7As shown in the figure, for the clamping structure between the convex part 34 of the bottle cap and the exhaust joint 32, the clamping structure includes a first buckle 341 and a second buckle 321. Specifically, for example, on both side walls of the exhaust joint 32, there are correspondingly arranged first buckles 341 that can be pressed. On the convex part 34 of the bottle cap of the cover body 33, a second buckle 321 is arranged at each position on both sides of the pipe joint. When the convex part 34 of the bottle cap covers the exhaust joint 32, the two first buckles 341 are correspondingly clamped with the two second buckles 321, realizing the clamping and locking between the convex part 34 of the bottle cap and the exhaust joint 32. When it is necessary to disassemble the bottle cap, by pressing the first buckles 341 on both sides of the exhaust joint 32, the two first buckles 341 can be separated from the two second buckles 321, thereby unlocking the cover body 33 and the bottle body 31, so as to conveniently open the cover body 33 and pour out the essential oil in the bottle body 31.

[0083] Optionally, a handle 335 is arranged on the cover body 33, which can make the loading and unloading between the cover body 33 and the bottle body 31 more convenient, and also make the loading and unloading between the liquid collection bottle 3 and the box body 1 more convenient.

[0084] Furthermore, as Figure 8 shown, the cupping device further includes a multi-way joint 5, a throttle valve 6, etc. The multi-way joint 5 has a first interface, a second interface and a third interface. The exhaust joint 32 is communicated with the first joint 114, the first joint 114 is communicated with the second joint 115, one end of a second air pipe 92 is connected to the second joint 115, and the other end of the second air pipe 92 is communicated with the first interface. The air extraction member 2 is communicated with the second interface through a third air pipe 93; the opening degree of the throttle valve 6 is adjustable, and the throttle valve 6 is communicated with the third interface through a fifth air pipe 95. By adjusting the opening degree of the throttle valve 6, the air pressure in the cupping tank body 8 can be correspondingly adjusted to meet different cupping requirements.

[0085] Optionally, an adjusting member is arranged on the box body 1, and the adjusting member is connected to the throttle valve 6 to be used for adjusting the opening degree of the throttle valve 6. The user can operate the adjusting member on the box body 1 to realize the adjustment of the opening degree of the throttle valve 6, and the operation is convenient. Of course, the present application is not limited to this. In other embodiments, the adjusting member may not be provided, but a terminal device (such as a mobile phone, a computer, a tablet, etc.) that establishes a signal connection with the box body 1 is used to control the throttle valve 6.

[0086] Optionally, as Figure 9 shown, the throttle valve 6 includes: a valve body 61, a screw rod 62, a nut 63, etc.

[0087] There is an air hole 611 provided inside the valve body 61; the screw rod 62 is connected to the adjusting member and can rotate under the drive of the adjusting member. The screw rod 62 is provided with an adjusting section 621 whose side surface is an inclined surface 622. The adjusting section 621 passes through the air hole 611. By axially moving the adjusting section 621 relative to the air hole 611, the gap size between the adjusting section 621 and the air hole 611 is adjusted. The third interface communicates with the gap between the adjusting section 621 and the air hole 611; the nut 63 is arranged on the valve body 61 and is restricted from rotating by the valve body 61. The screw rod 62 passes through the nut 63 and is in threaded cooperation with the nut 63. The screw rod 62 can rotate relative to the nut 63. Among them, when the screw rod 62 rotates, since the nut 63 is restricted by the valve body 61 and cannot rotate together with the screw rod 62, the thread structure between the nut 63 and the screw rod 62 will cause the screw rod 62 to move axially along the nut 63. By the axial movement of the screw rod 62, the gap size between the adjusting section 621 and the air hole 611 changes accordingly, and the exhaust flow rate of the cupping jar body 8 changes accordingly, realizing the adjustment of the air pressure inside the cupping jar body 8.

[0088] Optionally, in combination with Figure 1 and Figure 9 It can be understood that the adjusting member is an adjusting knob 132 arranged on the control panel 131. The adjusting knob 132 is in transmission connection with the screw rod 62. When the adjusting knob 132 is rotated, the adjusting knob 132 correspondingly drives the screw rod 62 to rotate.

[0089] Further optionally, as Figure 9 shown, a first gear 64, a second gear 65, and a potentiometer 66 are further arranged inside the box body 1. The potentiometer 66 is arranged on the circuit board inside the box body 1. The first gear 64 is connected between the adjusting knob 132 and the screw rod 62. When the adjusting knob 132 rotates, it drives the first gear 64 to rotate, and the first gear 64 drives the screw rod 62 to rotate. The second gear 65 is in meshing transmission with the first gear 64, and the potentiometer 66 is connected to the second gear 65. The potentiometer 66 forms a corresponding electrical signal in response to the rotation of the second gear 65 and transmits it to the circuit board for identifying the gear position at the throttle valve 6.

[0090] Furthermore, the cupping device further includes a solenoid valve 7. The multi-way joint 5 is a four-way joint for example. The multi-way joint 5 also has a fourth interface. The solenoid valve 7 is communicated with the fourth interface through the fourth air pipe 94.

[0091] Optionally, the solenoid valve 7 has an open state and a closed state. The air pressure inside the cupping jar body 8 is adjusted by the opening and closing of the solenoid valve 7. Optionally, the solenoid valve 7 is normally in the closed state. In the breathing cupping mode, by alternately opening and closing the solenoid valve 7, the pressure inside the cupping jar body 8 shows an alternately high and low change, so as to meet the requirements of different cupping modes.

[0092] Optionally, the air extraction member 2 is an air pump.

[0093] For the cupping device assembly and the cupping device of this embodiment, the air inlet joint 36 of the liquid collection bottle 3 is connected to the cupping tank body 8 through the first air tube 91. When pumping air, the cupping tank body 8 is adsorbed to the human skin, and the essential oil on the skin will be adsorbed into the first air tube 91. Since there is a liquid collection bottle 3 and a filter element 4 arranged between the first air tube 91 and the air pumping member 2, and the liquid collection bottle 3 is arranged on the box body 1, the essential oil will be filtered by the filter element 4 and flow into the liquid collection bottle 3, thereby playing a role in filtering essential oil and some substances such as hair and dandruff, and preventing the essential oil and some substances such as hair and dandruff from entering the rear-end air path (such as the second air tube 92, the third air tube 93, the fourth air tube 94, the fifth air tube 95, etc.) and components (such as the air pumping member 2, the solenoid valve 7, the throttle valve 6, etc.), thus ensuring the long-term normal use of the rear-end air path and components.

[0094] Embodiment Two

[0095] This embodiment discloses a cupping device assembly and a cupping device. The cupping device assembly includes a cupping device and one or more cupping tank bodies 8. The cupping tank body 8 can refer to the examples in Embodiment One in a non-conflicting manner and will not be elaborated here.

[0096] Please refer to Figure 10 , Figure 10 which shows the cupping device described in the second embodiment of the present application.

[0097] The difference from the above Embodiment One is that in this embodiment, the structure of the filter element 4 and the setting method of the filter element 4 are different from those in the above Embodiment One.

[0098] Specifically, in this second embodiment, as Figure 10 shown, one end of the cover body 33 facing the liquid collection cavity 35 is provided with an exhaust port 332, and the exhaust port 332 is communicated with the exhaust joint 32. As Figure 11 shown, the filter element 4 is in a sheet structure, and the filter element 4 is connected to the cover body 33 and blocks the exhaust port 332 of the cover body 33. For example, the filter element 4 is directly attached to the cover body 33 and covers the exhaust port 332 of the cover body 33. The gas in the liquid collection cavity 35 enters the exhaust port 332 of the cover body 33 after being filtered by the filter element 4.

[0099] In this embodiment, since the filter element 4 is arranged on the cover body, the filter element basically does not occupy the space for storing essential oil in the liquid collection cavity 35, which can reduce the frequency of pouring oil for cleaning and simplify the operation of the user.

[0100] Further optionally, the filter element 4 is a multi-layer structure, and the materials between each layer structure of the filter element 4 can be the same or different. Of course, in other embodiments, the filter element 4 can also be a single-layer structure.

[0101] Embodiment Three

[0102] This embodiment discloses a cupping device assembly and a cupping device. The cupping device assembly includes a cupping device and one or more cupping jars 8. The cupping jars 8 can refer to the examples in the first embodiment in a non-conflicting manner, which will not be elaborated here.

[0103] Please refer to Figure 12 , Figure 12 which shows the sectional structure of the liquid collecting bottle in the third embodiment of the present application.

[0104] The difference from the above-mentioned first and second embodiments is that the setting structure of the filter element 4 in the liquid collecting bottle 3 in this embodiment is different from that in the above-mentioned first and second embodiments.

[0105] Specifically, in the third embodiment, the filter element 4 is clamped between the cover body 33 and the bottle body 31. In this way, when the cover body 33 and the bottle body 31 are assembled and connected by capping, the filter element 4 can be clamped and limited by the cover body 33 and the bottle body 31, so as to realize the stability of the filter element 4 in the liquid collecting bottle 3. When the cover body 33 and the bottle body 31 are opened, the limit on the filter element 4 can be released accordingly to facilitate the removal of the filter element 4, with better use convenience, simpler structure and lower cost.

[0106] For example, in combination with Figure 12 , Figure 13 and Figure 14 it can be understood that the cover body 33 is provided with a first limit groove 336 or a first limit post, the bottom of the bottle body 31 protrudes towards the cover body 33 to form a support platform 312, the top of the support platform 312 is provided with a second limit post 313 or a second limit groove, one end of the filter element 4 is embedded in the first limit groove 336 or sleeved on the first limit post, and the other end of the filter element 4 is sleeved on the second limit post 313 or embedded in the second limit groove. When the cover body 33 and the bottle body 31 are capped, the filter element 4 is limited between the inner top surface of the first limit groove 336 and the support platform 312, that is, the cover body 33 and the bottle body 31 clamp and limit the filter element 4. At the same time, the first limit groove 336 and the second limit post 313 can limit the horizontal displacement of the filter element 4 in the liquid collecting bottle 3, better realizing the stability and positioning of the filter element 4.

[0107] Such as Figure 12As shown, the filter element 4 can be configured as a hollow annular structure. When the filter element 4 is clamped between the cover body 33 and the bottle body 31, the filter element 4 is positioned and limited by the first limiting groove 336 and the second limiting post 313, so that the hollow area of the filter element 4 communicates with the exhaust port 332 of the cover body 33 correspondingly. The gas in the liquid collection bottle 3 enters the hollow area inside the filter element 4 from the periphery of the filter element 4 and then is discharged along the exhaust port 332, while the substances filtered out by the filter element 4 are retained in the liquid collection bottle 3. This structure can achieve circumferential filtration of the filter element 4, with a larger filtration area. Moreover, compared with the structures of the first embodiment and the second embodiment, the installation and replacement of the filter element 4 in the liquid collection bottle 3 are more convenient and efficient. It is more convenient to remove the filter element for replacement. As long as the cover body 33 is opened, the filter element can be taken out, and no other disassembly and assembly operations are required.

[0108] Of course, it can be understood that the structure of the filter element 4 and the setting manner of the filter element 4 in the liquid collection bottle 3 are not limited to the examples of the first embodiment, the second embodiment, and the third embodiment. In other embodiments, a supporting basket can also be provided on the inner wall of the liquid collection bottle 3. The side wall of the basket is a mesh hole, and the filter element 4 can be placed in the basket. The gas enters the basket through the mesh hole and passes through the side wall of the filter element 4 into the exhaust port 332, etc.

[0109] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
