[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0032] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0033] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] The electrocardiograph in this application, such as Figures 1 to 7As shown in the figure, it includes a housing 1, a collection component 3, a display component 4, a power supply component 5, and a printing component 6. The housing 1 is divided into an upper shell, a middle shell, and a lower shell. The upper shell, the middle shell, and the lower shell form a cavity, and the collection component 3, the display component 4, the power supply component 5, and the printing component 6 are arranged in the cavity. The modular setting can save the internal space of the housing 1, and is convenient for disassembly and maintenance. The collection component 3 is an execution unit for collecting electrocardiogram data. The printing component 6 converts the electrocardiogram data collected by the collection component 3 onto an imaging medium.

[0035] Specifically, a paper bin opening is provided on the housing 1. The collection component 3 and the printing component 6 are arranged on the housing 1. The collection component 3 is used to collect electrocardiogram data, and the printing component 6 is used to receive the electrocardiogram data and convert the electrocardiogram data into an electrocardiogram waveform on an imaging medium. The printing component 6 includes a hook 671, a printing shaft 66, a printing body 67, and a paper bin door 61. The printing shaft 66 is arranged on the paper bin door 61. The hook 671 is rotatably connected to the printing body 67, enabling the hook 671 to rotate. The rotation path of the hook 671 at least includes a locked position and a disengaged position. In the locked position, the hook 671 can lock the printing shaft 66, so that the printing shaft 66 is spaced from the printing body 67 to form a channel 11, and the paper bin door 61 is fixedly covered on the paper bin opening. The printing shaft 66 can rotate relative to the paper bin door 61 and the hook 671 to drive the imaging medium through the channel 11. In the disengaged position, the hook 671 disengages from the printing shaft 66, and the paper bin door 61 can open the paper bin opening.

[0036] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: Through the locked state and the disengaged state of the printing shaft 66 by the hook 671, it is convenient for the paper bin door 61 to open and close the paper bin opening, so that the imaging medium is driven to move when the printing shaft 66 is in the locked state, and it is convenient for the storage and taking of the imaging medium, thereby achieving the effect of quickly opening and closing the paper bin opening. Specifically, when in use, the hook 671 locks the printing shaft 66, and the imaging medium passes through the channel formed by the space between the printing shaft 66 and the printing body 67. The printing shaft 66 drives the imaging medium through the channel so that the electrocardiogram data can be recorded. When the hook 671 disengages from the printing shaft 66, the paper bin door 64 opens the paper bin opening, which is convenient for the storage of the imaging medium and convenient for maintenance. Further, the imaging medium can be a recording paper 10 or a film.

[0037] Preferably, on the basis of the above embodiments, the printing assembly 6 further includes a rotating shaft 63 and a driving member 64. At least part of the driving member 64 is exposed outside the housing 1, and the exposed part of the driving member 64 outside the housing facilitates pressing the driving member 64 from outside the housing. Both ends of the rotating shaft 63 are respectively connected to the hook 671 and the driving member 64. The driving member 64 can drive the rotating shaft 63 to rotate to drive the hook 671 to rotate relative to the printing body 67. When the driving member 64 drives the rotating shaft 63 and the rotating shaft 63 drives the hook 671 to rotate relative to the printing body 67, the driving member 64 can be tilted along the rotating direction of the hook 671, so that the driving member 64 has a displacement in the rotating direction. In this embodiment, the rotating shaft 63 is parallel to the printing shaft 66. The arrangement of the rotating shaft 63 can keep the driving member 64 away from the printing shaft 66, so that the movement of the printing shaft 66 does not interfere with the movement of the driving member 64.

[0038] Further, the driving member 64 can be a button 641 or other parts convenient for driving the rotating shaft 63 to rotate. The button 641 is connected to the baffle 642, the baffle 642 is connected to the connecting member 643, and the connecting member 643 is connected to the rotating shaft 63. When the button 641 is pressed, the button 641 moves in an arc shape with a downward tilt. The button 641 drives the baffle 642 to move in an arc shape with a tilt. The baffle 642 drives the connecting member 643 and the rotating shaft 63 to move in an arc shape with a downward tilt. The rotating shaft 63 drives the hook 671 to rotate relative to the printing body 67. When the button 641 is released, the baffle 642 abuts against the inside of the housing 1, so that when in the locked state, the rotating shaft 63 is parallel to the printing shaft 66.

[0039] As Figure 8 and Figure 9 shown, in addition, in some other embodiments, the printing assembly 6 further includes a printing bracket 62, a first gear 68, a second gear 661, a gear set 65, a damping member, a third gear 69, and a reset member 12. The printing bracket 62 and the third gear 69 are arranged on the housing. The damping member is used to provide a damping force to the third gear 69. The first gear 68 is arranged on the paper bin door 61 and meshes with the third gear 69. Further, the damping member can be a torsion spring or a friction member. One end of the torsion spring is respectively connected to the third gear 69 and the printing bracket 62. When the third gear 69 rotates, the torsion spring provides a resistance to prevent the third gear 69 from rotating. The friction member is arranged on one side of the third gear and contacts the printing body 62. When the third gear rotates, the friction member provides a resistance. The arrangement of the damping member can prevent the paper bin door 61 from colliding with the external structure and being damaged due to no resistance when the paper bin door 61 is opened.

[0040] In addition, a second gear 661 is provided on the printing shaft 66, and a gear set 65 is provided on the printing body. When the paper bin door 61 is fixedly covered on the paper bin opening, the second gear 661 can be engaged with the gear set 65. The motor on the gear set 65 drives the gear set 65 to rotate, and the gear set 65 can drive the printing shaft 66 to rotate through the second gear 661, so as to drive the imaging medium through the channel 11.

[0041] Furthermore, the driving member 64 and the printing bracket 62 are connected by a reset member 12 to drive the driving member 12 to reset. The reset member 12 can be a spring or a tensile reset rubber member. In Figure 10 the driving member 64 is in a horizontal state, and the printing shaft 66 is in a locked state by the hook 671. At this time, the second gear 661 on the printing shaft 66 is engaged with the gear set 65 on the printing assembly 6, and the reset member 12 is in a natural contraction state. As Figure 11 shown in, when the driving member 64 is pressed, the driving member 64 pulls the reset member 12, and the driving member 64 tilts around the rotating shaft 63. The hook 671 rotates, so that the printing shaft 66 is extruded from the buckled state. When the driving member 64 is continuously pressed, the meshing state between the second gear 661 on the printing shaft 66 and the gear set 65 is completely disengaged, and the paper bin door 61 is completely opened. At this time, the imaging medium can be taken out or added to the paper bin. In Figure 10 when the driving member 64 is released, under the action of the reset member 12, the driving member 64, the rotating shaft 63 and the hook 671 are reset. When the paper bin door 61 needs to be closed, the paper bin door 61 is pushed. The paper bin door 61 drives the printing shaft 66 to move. When the printing shaft 66 abuts against the upper inclined surface of the hook 671, the printing shaft 66 drives the hook 671, the rotating shaft 63 and the driving member 64 to tilt. The driving member 64 and the printing bracket 62 pull the reset member 12, and the printing shaft 66 continues to move. When the printing shaft 66 is completely locked by the hook 671, under the pulling force of the reset member 12, the hook 671, the rotating shaft 63 and the driving member 64 are reset, and the reset member 12 is in a natural contraction state. At this time, the paper bin door 61 covers the paper bin opening.

[0042] As Figures 1 - 4 shown, in addition, in some embodiments, the electrocardiograph includes a display assembly 4. The display assembly 4 includes a touch screen 40, a first shielding cover 41 and a first adapter board 42. The first shielding cover 41 is provided on the housing 1. The touch screen 40 is provided on the first shielding cover 41 and at least partially exposed on the housing 1. The first adapter board 42 is electrically connected to the touch screen 40. A part of the touch screen 10 is exposed on the housing 1 to enable a user to touch the touch screen.

[0043] Further, the display component 4 further includes a first connector 47, a second connector 48, a conversion board 44, a main board 43, a sheet metal part 45, and a second adapter board 46. The first adapter board 42 is electrically connected to the second connector 48 through the first connector 47. The second connector 48 is electrically connected to the main board 43. The conversion board 44 is fixed to the housing 1 through the sheet metal part 45. The conversion board 44 is electrically connected to the main board 43 and is also electrically connected to the printing component 6. When the printing button is pressed, the first adapter board 42 receives a signal and transmits it to the main board 43 through the first connector 47 and the second connector 48. The main board 43 transmits the signal to the printing component 6 through the conversion board 44 for displaying the imaging medium.

[0044] The main board 43 is provided with a plurality of interfaces 431. Further, the interfaces 431 include a USB interface 4313, a USB type C interface 4312, and an HDMI interface 4311, which facilitate connection with other devices. The main board 43 is also provided with a speaker 7 for reminding the user of the status during use.

[0045] As Figure 5 shown, in addition, the electrocardiograph also includes a power supply component 5. The power supply component 5 is provided in the housing 1 and includes a second shield 52, a power supply unit 53, a socket 56, a grounding terminal 55, an input connection line 54, and an output connection line 51. The power supply unit 53 and the input connection line 54 are provided inside the second shield 52. The socket 56 is electrically connected to the input connection line 54. The grounding terminal 55 is provided on the second shield 52 so that when an abnormal fault occurs in the power supply component 5, a good grounding condition can be achieved through the grounding terminal 55 for the safety measure of the device in case of an abnormal fault.

[0046] The input connection line 54 is electrically connected to the power supply unit 53. The power supply unit 53 is electrically connected to the output connection line 51. The output connection line 51 is electrically connected to the conversion board 44. Alternating current can be delivered to the power supply unit 53 through the socket 56 and the input connection line 54 and then delivered to the conversion board 44 through the output connection line 51, so that the conversion board 44 can supply power to the acquisition component 3, the printing component 6, and the display component 4. The conversion board 44 can convert the alternating current of the power supply component 5 into direct current to supply power to the acquisition component 3, the printing component 6, and the display component 4.

[0047] As Figure 6As shown in the figure, in addition, the acquisition component 3 includes a third shield 32, a lead interface 31, an acquisition board 33, and a terminal block 34. The third shield 32 and the terminal block 34 are arranged on the acquisition board 33, and the lead interface 31 is located below the third shield 32 and arranged on the acquisition board 33. The lead interface 31 connects the lead wire to the human body, and the electrocardiogram data is collected on the acquisition board 33 through the lead wire. The acquisition board 33 transmits the electrocardiogram data to the display component 4 and the printing component through the connection wire. In this way, when the print key is pressed, the signal is converted into a waveform and transmitted to the main board 43 through the first adapter board 42, the first connector 47, and the second connector 48. The main board 43 transmits it to the conversion board 44, and the conversion board 44 transmits it to the printing component 6, and records the human electrocardiogram wave through the printing component 6.

[0048] As Figure 9 shown in the figure, in addition, a battery slot is provided on the housing 1, and the battery slot is used to accommodate the battery 8. A cover 9 for covering the battery slot is provided on the housing 1. The battery 8 can directly supply power to the electrocardiogram recorder through the second adapter board 46, and the power supply component 5 charges the battery 8 through the conversion board 44 and the second adapter board 46.

[0049] Preferably, the cover 9 is snap-connected to the housing 1 to cover the battery slot. The covering of the cover 9 facilitates the replacement of the battery 8.

[0050] As Figure 4 shown in the figure, in addition, a groove is provided on the housing 1, and the electrocardiogram recorder further includes a handle 10. The handle 10 is rotatably connected to the housing 1 so as to be rotatably received in the groove. The hidden handle 10 improves the aesthetics of the electrocardiogram recorder and is convenient for moving and carrying.

[0051] As Figure 1 and Figure 2 shown in the figure, in addition, a key slot is provided on the housing 1, and a key 2 is provided in the key slot. The key 2 includes a silicone key 21, a key board 22, and a key fixing plate 23. In this way, the functions of the electrocardiogram recorder can be operated through the key 2.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
