Description

Technical Field

[0001] This application relates to the field of heat transfer equipment technology, and in particular to a heat transfer machine. Background Technology

[0002] A heat transfer machine is a device that uses heat and pressure to transfer a pattern from a transfer film onto the surface of a target object, thus achieving heat transfer. A typical heat transfer machine includes an upper body and a lower body that can rotate relative to each other. The upper body includes a heating element for heating and pressurizing the target object, and the lower body includes a support element for supporting the target object.

[0003] Before heat transfer, the upper body needs to be rotated to the appropriate position so that the heating element is aligned with the carrier to avoid misalignment of the heat transfer pattern or uneven pressure. This process is usually performed manually by the operator, who then calibrates it visually and based on experience. This not only takes a lot of time but is also prone to insufficient positioning accuracy. Utility Model Content

[0004] To solve the above-mentioned technical problems, embodiments of this application provide a heat transfer machine, which includes an upper body, a lower body, and a rotating support. The rotating support includes a rotating shaft, and the upper body and the lower body are rotatably connected by the rotating shaft, so that the upper body can rotate relative to the lower body in a first direction or a second direction, wherein the first direction is opposite to the second direction. The rotating bracket also includes a first feedback section and a second feedback section. One of the first feedback section and the second feedback section is fixed relative to the upper body and the other is fixed relative to the lower body. The first feedback section and the second feedback section are configured to provide tactile feedback when the upper body rotates relative to the lower body to a first preset position.

[0005] The beneficial effects of the heat transfer machine provided in this application are: This application provides tactile feedback by setting a first feedback unit and a second feedback unit that can provide tactile feedback when the upper and lower bodies rotate to the first preset position. This allows the heat transfer machine to provide tactile feedback to the operator when the upper body rotates relative to the lower body to the desired position, thus helping the operator to judge whether the upper body has rotated into place. This reduces the difficulty of operating the heat transfer machine and improves the positioning accuracy of the upper and lower bodies. Attached Figure Description

Detailed Implementation

[0008] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details.

[0009] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0010] This application provides a heat transfer printer. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1This is a schematic plan view of the heat transfer machine provided in some embodiments of this application. Figure 2 yes Figure 1 A cross-sectional view of the heat transfer machine in the embodiment.

[0011] In some embodiments, the heat transfer machine 10 includes an upper body 100, a lower body 200, and a rotating bracket 300. The rotating bracket 300 connects the upper body 100 and the lower body 200 respectively, and the upper body 100 and the lower body 200 can be rotatably connected through the rotating bracket 300, so that the user can control the upper body 100 to rotate relative to the lower body 200.

[0012] The rotating support 300 includes a rotating shaft 310. The upper body 100 and the lower body 200 are rotatably connected via the rotating shaft 310, allowing the upper body 100 to rotate relative to the lower body 200 along a first direction A or a second direction B. The first direction A is opposite to the second direction B. Rotation of the upper body 100 relative to the lower body 200 along the first direction A can be considered clockwise rotation, and rotation along the second direction B can be considered counterclockwise rotation. The rotating shaft 310 can be connected to the upper body 100 and the lower body 200 via bearings or other transmission devices to achieve smooth rotation of the upper body 100. In other embodiments, the rotating shaft 310 can also be directly connected to the upper body 100 and the lower body 200.

[0013] The upper body 100 and lower body 200 are used to perform heat transfer on a target object. During heat transfer, the user places the target object on the lower body 200 and then lowers the upper body 100 so that it cooperates with the lower body 200 to press the target object. At least one of the upper body 100 and lower body 200 is also configured to generate heat, thereby allowing the upper body 100 and lower body 200 to heat and pressurize the target object to achieve heat transfer.

[0014] In some embodiments, the upper body 100 may include a rotating base 110 and a heating element 120 disposed on the rotating base 110, and the lower body 200 may include a base 210 and a support member 220 disposed on the base 210. Both the heating element 120 and the support member 220 may be, but are not limited to, plates. The support member 220 is used to support a target object, and the heating element 120, in conjunction with the support member 220, heats and pressurizes the target object and the heat transfer film covering the target object to transfer the pattern on the heat transfer film onto the target object. The target object may be, for example, clothing, fabric, or film.

[0015] The rotating base 110 and the base 210 are rotatably connected by a rotating shaft 310, allowing the upper body 100 to rotate relative to the lower body 200 along either the first direction A or the second direction B. The specific structures of the upper body 100 and the lower body 200 can be designed as needed, as long as they are two bodies capable of performing heat pressing on the target object. For example, the lower body 200 can be designed with a heating component, while the upper body 100 is responsible for pressurizing the target object; or both the upper body 100 and the lower body 200 can have heating functions.

[0016] Before heat transfer, the upper body 100 needs to rotate relative to the lower body 200 until the heating element 120 is aligned with the carrier 220, i.e., the 0-degree position, which is usually referred to as the correct position. After heat transfer, the upper body 100 can be rotated from the correct position to other positions by the user to facilitate the removal of the target object. It can be understood that the relative rotation between the upper body 100 and the lower body 200 causes the rotating base 110 to rotate relative to the base 210; that is, the relative rotation of the upper body 100 and the lower body 200 mentioned in the text can be understood as the relative rotation of the rotating base 110 and the base 210.

[0017] The upper body 100 is connected to the rotating support 300 via a rotating base 110, and the lower body 200 is connected to the rotating support 300 via a base 210. The heating element 120 can move relative to the rotating base 110 along the height direction of the heat transfer machine 10. Therefore, after the upper body 100 rotates to the correct position, the heating element 120 can move towards the carrier 220 under user operation to achieve heat transfer. The specific structures of the upper body 100 and the lower body 200 are not detailed here; they can be designed according to specific needs.

[0018] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0019] The rotating support 300 includes a first feedback unit 410 and a second feedback unit 420. One of the first feedback unit 410 and the second feedback unit 420 is fixed relative to the upper body 100, and the other is fixed relative to the lower body 200. The first feedback unit 410 and the second feedback unit 420 are configured to cooperate in providing tactile feedback. It should be noted that tactile feedback refers to a signal that can be perceived by the user's touch, transmitted to the user's operating part (such as a handle) through changes in mechanical force, such as, but not limited to, vibration, changes in rotational resistance, etc. Tactile feedback can be used to indicate to the user that the upper body 100 has rotated to a preset position relative to the lower body 200.

[0020] In some embodiments, the rotating bracket 300 may further include a first connector 320 and a second connector 330. One of the first connector 320 and the second connector 330 is fixed relative to the upper body 100, and the other is fixed relative to the lower body 200. A first feedback unit 410 is disposed on the first connector 320, and a second feedback unit 420 is disposed on the second connector 320. In other embodiments, the first feedback unit 410 and the second feedback unit 420 may also be directly disposed on the upper body 100 and the lower body 200, or indirectly disposed on the upper body 100 and the lower body 200 through other means. The specific structures of the first feedback unit 410 and the second feedback unit 420 will be described in detail below.

[0021] For ease of understanding, the following description mainly uses the example of the first connector 320 being fixed relative to the upper body 100 and the second connector 330 being fixed relative to the lower body 200. In other embodiments, the positions and connection methods of the first connector 320 and the second connector 330 can also be interchanged, and the orientation of the limiting structures provided on the first connector 320 and the second connector 330 will also be reversed accordingly.

[0022] This embodiment of the application provides two connecting members that are respectively fixed to the upper body 100 and the lower body 200, allowing the heat transfer machine 10 to restrict the rotation of the upper body 100 and the lower body 200 through the cooperation of the two connecting members. The restriction structure design may include at least one of tactile feedback design and limit design, which will be described in detail below.

[0023] The first connecting member 320 can be fixed relative to the rotating seat 110, and the second connecting member 330 can be fixed relative to the base 210. The first connecting member 320 is fixedly connected to the rotating seat 110, and the second connecting member 330 is fixedly connected to the base 210. Optionally, the rotating bracket 300 includes an upper sleeve 340, which is sleeved on the first connecting member 320 and part of the rotating shaft 310. The first connecting member 320 is fixedly connected to the rotating seat 110 through the upper sleeve 340. The connection method between the upper sleeve 340 and the rotating seat 110 is, for example, but not limited to, snap-fit ​​or nail-fit. Optionally, the rotating bracket 300 includes a lower sleeve 350, which is sleeved on the second connecting member 330 and part of the rotating shaft 310. The second connecting member 330 is fixedly connected to the base 210 through the lower sleeve 350. The connection method between the lower sleeve 350 and the base 210 is, for example, but not limited to, snap-fit ​​or nail-fit. Optionally, the rotating bracket 300 includes an outer sleeve 360, which is connected between the rotating seat 110 and the base 210 and cooperates with the rotating seat 110 and the base 210 to cover the rotating shaft 310. The outer surface of the outer sleeve 360 ​​can form the outer surface of the rotating bracket 300.

[0024] In other embodiments, the first connector 320 can also be fixed to the upper body 100 in other ways. For example, the first connector 320 can be fixed to the rotating base 110 by a component of other shapes. Or, the first connector 320 can be fixed to the rotating base 110 by a rotating shaft 310, while the second connector 330 is fixed to the base 210 and is separate from or rotatably connected to the rotating shaft 310. Similarly, the second connector 330 can also be fixed to the lower body 200 in other ways, which will not be elaborated further.

[0025] In this embodiment, both the first connecting member 320 and the second connecting member 330 can be sleeved on the rotating shaft 310 to facilitate their cooperation in restricting the upper body 100 and the lower body 200. One of the first connecting member 320 and the second connecting member 330 can rotate relative to the rotating shaft 310, while the other is fixed relative to the rotating shaft 310. In other embodiments, the first connecting member 320 and the second connecting member 330 can also be designed in other shapes as needed and fixed on one side of the rotating shaft 310, or spaced apart from the rotating shaft 310, and are not limited to being sleeved on the rotating shaft 310. The following description mainly uses the example of both the first connecting member 320 and the second connecting member 330 being sleeved on the rotating shaft 310.

[0026] Understandably, all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0027] Please see Figure 3 and Figure 4 . Figure 3 This is a partial assembly structure diagram of the rotating bracket provided in some embodiments of this application. Figure 4 yes Figure 3 A partially exploded structural diagram of the rotating bracket in the embodiment.

[0028] In some embodiments, the first feedback unit 410 is disposed on the first connector 320, and the second feedback unit 420 is disposed on the second connector 330. The first feedback unit 410 and the second feedback unit 420 are flexible in design and can be designed as independent structural components, allowing for independent installation, maintenance, or replacement; or they can be integrated into the connector as part of it.

[0029] The first feedback unit 410 and the second feedback unit 420 are used to provide tactile feedback when the upper body 100 rotates relative to the lower body 200 to a first preset position. The first preset position is, for example, but not limited to, the 0-degree position during heat transfer, i.e., the positive position. Figure 1 The upper body 100 shown is in the correct position. For ease of explanation, the state of the heat transfer machine 10 when the upper body 100 is rotated relative to the lower body 200 to the first preset position is referred to as the first state. The first state includes, but is not limited to, the state in which the upper body 100 is in the correct position.

[0030] Since the first connector 320 is fixed relative to the upper body 100 and the second connector 330 is fixed relative to the lower body 200, when the upper body 100 rotates relative to the lower body 200 along the first direction A or the second direction B, the upper body 100 will drive the first connector 320 to rotate relative to the second connector 330. In this embodiment, a first feedback part 410 is provided on the first connector 320, and a second feedback part 420 that can cooperate with the first feedback part 410 is provided on the second connector 330. This allows the first feedback part 410 to rotate to a specific position relative to the second feedback part 420 in the first state, and to cooperate with the second feedback part 420 to provide tactile feedback.

[0031] The specific structures of the first feedback unit 410 and the second feedback unit 420 can be designed as needed, as long as they can achieve the above-mentioned functions. For example, the first feedback unit 410 can be a protrusion provided on the surface of the first connector 320 facing the second connector 330, and the second feedback unit 420 can be a protrusion provided on the surface of the second connector 330 facing the first connector 320. In the first state, the first feedback unit 410 and the second feedback unit 420 can overlap along the axial direction of the rotating shaft 310 and press against each other, thereby increasing the rotational resistance of the upper body 100. The sudden increase in rotational resistance can serve as tactile feedback. Here, the axial direction of the rotating shaft 310 can be regarded as the height direction of the heat transfer machine 10. At least one of the first feedback unit 410 and the second feedback unit 420 can be made of flexible material.

[0032] In other embodiments, the first feedback portion 410 is elastically and telescopically disposed on the first connector 320, and the second feedback portion 420 is a groove corresponding to a first preset position. The first feedback portion 410 abuts against the second connector 330 and slides with the second connector 330. When the upper body 100 rotates relative to the lower body 200 to the first preset position, the first feedback portion 410 and the second feedback portion 420 overlap, causing the first feedback portion 410 to elastically reset and at least partially enter the groove to provide tactile feedback. The first connector 320 and the second connector 330 are arranged axially along the shaft 310.

[0033] Optionally, during the rotation of the upper body 100 relative to the lower body 200, the first feedback unit 410 always abuts against the second connecting member 330 to provide rotational damping, so that the heat transfer machine 10 can provide the user with a good operating feel.

[0034] In some embodiments, the first feedback unit 410 can interact with the second connector 330 through elastic pressing to provide rotational damping during the rotation of the upper body 100 relative to the lower body 200. Specifically, the first feedback unit 410 can be designed to include an elastic element, such as a spring, which applies continuous elastic pressure when it abuts against the second connector 330. This elastic pressing mechanism generates frictional resistance during rotation, thereby providing rotational damping, preventing excessively fast or uncontrolled rotation, and improving the stability and handling of the device.

[0035] In other embodiments, the first feedback unit 410 can also be designed as other structures capable of providing the aforementioned rotational damping. For example, the first feedback unit 410 can be designed as a flexible protrusion, which can be, but is not limited to, a protruding structure made of rubber or silicone, and continuously abuts against the second connector 330 throughout the entire rotation of the upper body 100 relative to the lower body 200 to provide uniform rotational damping. The elastic properties of the flexible protrusion ensure that the first connector 320 remains in contact with the second connector 330 at all times, generating resistance through sliding friction. Meanwhile, the second feedback unit 420 can be designed as a protrusion or groove structure adapted to the first feedback unit 410, and when the upper body 100 rotates relative to the lower body 200 to a preset position, it cooperates with the first feedback unit 410 to generate different tactile feedback.

[0036] Therefore, in non-first state, the first feedback part 410 will press against the first connector 320 and slide against it, keeping the rotational resistance of the upper body 100 at a relatively large value. When the heat transfer machine 10 switches to the first state, the first feedback part 410 and the second feedback part 420 overlap. At this time, the groove space of the second feedback part 420 can accommodate at least part of the first feedback part 410, so the first feedback part 410 will elastically reset and get stuck in the second feedback part 420, so that the rotational resistance of the upper body 100 drops sharply. This sharp drop in the rotational resistance of the upper body 100 can serve as tactile feedback. The following explanation will mainly use this as an example.

[0037] In some embodiments, the bottom surfaces of the grooves at both ends of the second feedback section 420 along the first direction A can be surfaces with gradually varying heights, and the height of the groove bottom surface increases closer to the end edge of the second feedback section 420. In other words, the two ends of the second feedback section 420 along the rotation direction exhibit a trend of gradually increasing from the inside to the outside, and the groove bottom surfaces at both ends are higher closer to the end edges. Figure 3 Taking the second feedback section 420 shown as an example, the second feedback section 420 extends in the horizontal direction. The bottom surface of the groove at the left end of the second feedback section 420 gradually increases in the left direction, and the bottom surface of the groove at the right end of the second feedback section 420 gradually increases in the right direction.

[0038] Along the first direction A, the height of the bottom surface of the second feedback unit 420 can gradually decrease first and then gradually increase. Understandably, the second direction B is opposite to the first direction A; therefore, along the second direction B, the height of the bottom surface of the second feedback unit 420 also gradually decreases first and then gradually increases. In other words, the bottom surface of the second feedback unit 420 can be composed of two inclined surfaces.

[0039] In the first state, the first feedback part 410 can simultaneously abut against the bottom surface of the groove on both sides of the second feedback part 420. For example, the first feedback part 410 can be exactly in the middle of the second feedback part 420, so that the inclined surfaces on both sides of the second feedback part 420 will apply a normal constraint force to the first feedback part 410, which can resist vibration and reduce the possibility of the upper body 100 rotating incorrectly in the first state, so that the heat transfer machine 10 can stably maintain the first state when performing heat transfer.

[0040] The bottom surface of the groove of the second feedback part 420 may include two arc-shaped surfaces, so that the bottom surface of the groove of the second feedback part 420 can have a U-shaped appearance when viewed from the side perpendicular to the rotation axis 310. The bottom surface of the groove of the second feedback part 420 may also include two inclined planes, so that the bottom surface of the groove of the second feedback part 420 can have a V-shaped appearance when viewed from the side. Optionally, the outer surface of the first feedback part 410 facing the second connector 330 is arc-shaped, and the second feedback part 420 is an arc-shaped groove with its opening facing the first connector 320. The arc-shaped outer surface of the first feedback part 410 is adapted to the arc-shaped bottom surface of the groove of the second feedback part 420; in other words, the first feedback part 410 can slide into or out of the second feedback part 420 along the bottom surface of the groove.

[0041] In other embodiments, the bottom surface of the groove of the second feedback section 420 may also include inclined surfaces on both sides of the second feedback section 420 and a transition surface connecting the two inclined surfaces. The transition surface may be an arc surface or a plane. The inclined surfaces on both sides of the second feedback section 420 can be used to guide the first feedback section 410 into and out of the second feedback section 420. Alternatively, the second feedback section 420 may not have inclined surfaces, meaning the bottom surface height of the groove at both ends of the second feedback section 420 along the first direction A remains consistent.

[0042] In some embodiments, the first feedback part 410 may be in clearance fit with the second feedback part 420. Specifically, when the upper body 100 rotates relative to the lower body 200 to a first preset position, the first feedback part 410 is at least partially located in the second feedback part 420, and there is a gap between them. In other words, the first feedback part 410 may only partially fit against the bottom surface of the groove of the second feedback part 420 in the first state, thereby preventing the upper body 100 from being locked when it starts to rotate in the first state. In other embodiments, the first feedback part 410 may also be completely fitted with the second feedback part 420 in the first state without any gap. The heat transfer machine 10 can adjust the angle and height of the first feedback part 410 and the second feedback part 420 so that the first feedback part 410 can disengage from the second feedback part 420 after entering it.

[0043] In this embodiment, the first feedback unit 410 is designed as an elastically extendable structure, allowing it to engage with the second feedback unit 420 in the first state and compress the second connector 330 in the non-first state. This results in different rotational resistances for the upper body 100 in the first and non-first states, thereby providing tactile feedback when the heat transfer machine 10 switches to the first state. It is understood that there are at least one first feedback unit 410 and at least one second feedback unit 420, and the first preset position can be one or more.

[0044] The specific structure of the first feedback unit 410 can be designed as needed, as long as it can achieve the elastic extension and retraction function described above. In some embodiments, the rotating bracket 300 further includes an elastic element 430, which abuts against the first feedback unit 410, allowing the first feedback unit 410 to extend and retract elastically. This will be used as an example in the following description. In other embodiments, the first feedback unit 410 may itself be an elastic body, thus eliminating the need for the elastic element 430.

[0045] Optionally, the rotating bracket 300 includes an abutment member 440. The abutment member 440 is hinged to the first connector 320, and one end of the abutment member 440 forms a first feedback portion 410. An elastic member 430 is disposed on the side of the first feedback portion 410 opposite to the second feedback portion 420, and both ends of the elastic member 430 abut against the first feedback portion 410 and the first connector 320, respectively.

[0046] The first feedback portion 410 may be formed at the end of the abutment member 440 away from its hinge position with the first connector 320. For example, the abutment member 440 may be elongated, with one end hinged to the first connector 320 and the other end forming the first feedback portion 410. In other embodiments, the abutment member 440 may also be designed in other shapes, and the portion of the abutment member 440 forming the first feedback portion 410 is not limited to the above embodiments. For example, the abutment member 440 may integrally form the first feedback portion 410.

[0047] The elastic element 430 is a resiliently expandable component, specifically a spring or an elastic material such as elastic rubber. When the elastic element 430 abuts against the first feedback part 410, it is in a compressed state. The elastic element 430 provides the first feedback part 410 with a force toward the second connecting member 330, ensuring that the first feedback part 410 remains in contact with the second connecting member 330. Optionally, the first connecting member 320 may have a groove for accommodating the elastic element 430. The elastic element 430 may be partially contained within this groove, with the other part extending out of the groove and abutting against the first feedback part 410.

[0048] Through the above design, the heat transfer machine 10 can sequentially undergo the following processes during the transition from a non-first state to the first state: (1) When the upper body 100 rotates relative to the lower body 200, the first feedback part 410 and the second feedback part 420 are in a separated state, and the operating torque is constant; (2) When the upper body 100 rotates to a position close to the first preset position, the first feedback part 410 will contact the inlet end surface of the second feedback part 420, and the elastic member 430 will force the first feedback part 410 to slide into the second feedback part 420; wherein, the distance between the position of the upper body 100 when the first feedback part 410 and the second feedback part 420 begin to contact and the first preset position can be designed as needed. Taking the first preset position corresponding to the rotation angle 0 as an example, the upper body 100 00 The position of the first feedback part 410 when it begins to contact the second feedback part 420 may be, but is not limited to, the corresponding rotation angle 0 ± 0.5 degrees; (3) When the first feedback part 410 enters the second feedback part 420, the rotational resistance of the upper body 100 drops suddenly, forming a sudden change in operating force of, for example, but not limited to, 5-10N. This change will be transmitted to the upper body 100 through the rotating shaft 310, giving the user a clear tactile signal; (4) After the first feedback part 410 enters the second feedback part 420, the inclined surfaces on both sides of the second feedback part 420 will generate a normal constraint force on the first feedback part 410. This normal constraint force may be, but is not limited to, greater than 15N, thereby resisting vibration offset and ensuring that the position of the upper body 100 is locked, so that the offset of the upper body 100 is < ± 0.1°.

[0049] Therefore, the tactile feedback design described above in this application embodiment facilitates the accurate positioning of the upper body 100, and can reduce or even eliminate deviations caused by operator visual calibration.

[0050] In this embodiment, the heat transfer machine 10 may further include a limiting design. The limiting design may coexist with the haptic feedback design described above in the same embodiment, or it may exist independently in a separate embodiment, depending on the specific design requirements. The following description uses an example of the limiting design and the haptic feedback design coexisting in the same embodiment. The limiting design can be embodied in the aforementioned rotating bracket 300.

[0051] Please see Figure 5 and Figure 6 , Figure 5 This is a partial cross-sectional structural diagram of the rotating bracket provided in some embodiments of this application. Figure 6 This is a three-dimensional structural schematic diagram of the first connector provided in some embodiments of this application. The second state is the state of the heat transfer machine 10 when the upper body 100 rotates relative to the lower body 200 to a second preset position. The second preset position is different from the first preset position.

[0052] In some embodiments, the first connector 320 may be provided with a limiting portion 510. When the upper body 100 rotates relative to the lower body 200 to a second preset position, the first connector 320 abuts against the second connector 330 through the limiting portion 510 to prevent the upper body 100 from rotating further relative to the lower body 200.

[0053] The number of limiting parts 510 can be at least one. The upper body 100 can rotate relative to the lower body 200 along the first direction A to a second preset position. At this time, the limiting part 510 can directly or indirectly abut against the second connecting member 330 to prevent the upper body 100 from rotating further along the first direction A. The upper body 100 can also rotate relative to the lower body 200 along the second direction B to a second position. At this time, the limiting part 510 can directly or indirectly abut against the second connecting member 330 to prevent the upper body 100 from rotating further along the first direction A. The following description mainly uses this as an example. In other embodiments, the limiting part 510 can also be configured to: abut the second connecting member 330 at one preset position along the first direction A, and abut the second connecting member 330 at another preset position along the second direction B.

[0054] The second preset position can be the position where the upper body 100 is rotated 180 degrees relative to the lower body 200. It should be noted that the position where the upper body 100 rotates to 0 degrees corresponds to the position where the heating element 120 is aligned with the support element 220, i.e., the correct position; correspondingly, the position where the upper body 100 rotates to 180 degrees is the position where the upper body 100 rotates half a turn from the correct position along the first direction A or the second direction B. The second preset position can also be other positions, such as the position where the upper body 100 rotates to 120 degrees, and is not specifically limited. The following explanation mainly uses the position where the upper body 100 rotates to 180 degrees as an example.

[0055] This embodiment of the application provides a limiting part 510 in the first connecting member 320, allowing the limiting part 510 to form a limiting engagement with the second connecting member 330 along the rotation direction. This prevents excessive rotation of the upper body 100, which could lead to dangerous phenomena such as deformation of the rotating shaft 310, collision of the heating element 120, or tearing of electrical cables, thus improving the safety of the heat transfer machine 10. In other embodiments, the heat transfer machine 10 may not employ a limiting design.

[0056] The specific structure of the limiting part 510 and its cooperation with the first connecting member 320 and the second connecting member 330 can be designed as needed. For example, the limiting part 510 can be a rigid stop provided on the first connecting member 320, and another rigid stop can be provided on the second connecting member 330. When the upper body 100 rotates relative to the lower body 200 to the second preset position, the two rigid stops can abut against each other to prevent the upper body 100 from rotating further relative to the lower body 200. The limiting effect can also be achieved by other limiting structures in the embodiments of this application.

[0057] Please see Figures 5 to 10 , Figure 7 This is a three-dimensional structural diagram of the second connector and limiting member provided in some embodiments of this application in a second state. Figure 8 yes Figure 7 The diagram shows the three-dimensional structure of the second connector and the limiting member in the third state. Figure 9 This is a cross-sectional structural diagram of a portion of the rotating bracket provided in some embodiments of this application in a second state. Figure 10 yes Figure 9 The diagram shows a cross-sectional view of the rotating support in the third state. The third state is the position of the heat transfer machine 10 when the upper body 100 rotates relative to the lower body 200 to the third preset position. The third preset position is different from the first preset position.

[0058] In some embodiments, the rotating bracket 300 further includes a limiting member 520. The limiting member 520 is movably disposed on the second connecting member 330 and is used to cooperate with the limiting part 510 to achieve limiting. The second connecting member 330 may be provided with a limiting track 530 extending along a first direction A. The limiting member 520 is disposed on the limiting track 530 and is configured to move along the limiting track 530 and be stopped by the end of the limiting track 530. The specific shapes of the limiting member 520 and the limiting track 530 can be described as needed, and will be elaborated below.

[0059] Along the axial direction of the rotating shaft 310, at least a portion of the limiting member 520 is at the same height as the limiting portion 510, so that the limiting portion 510 can contact the limiting member 520 when rotating along the first direction A or the second direction B. When the upper body 100 rotates relative to the lower body 200 along the first direction A to a second preset position, one end of the limiting portion 510 and the limiting track 530 respectively abuts against both sides of the limiting member 520. When the upper body 100 rotates relative to the lower body 200 along the second direction B to a third preset position, the other end of the limiting portion 510 and the limiting track 530 respectively abut against both sides of the limiting member 520.

[0060] Compared to two fixed rigid blocks that cooperate to stop and limit, this embodiment stops and limits by cooperating the limiting part 510 with the limiting member 520 that can move along the limiting track 530. This allows the limiting part 510 to push the limiting member 520 to abut against one end of the limiting track 530 when the upper body 100 rotates in the first direction A, and to push the limiting member 520 to abut against the other end of the limiting track 530 when the upper body 100 rotates in the second direction B. The limiting member 520 also cooperates with the end of the limiting track 530 to abut against both sides of the limiting member 520. Thus, the limiting member 520 can abut against the limiting part 510 at different positions when the upper body 100 rotates forward and backward, thereby compensating for the angle loss caused by rigid limiting.

[0061] Understandably, since the two opposing rigid stops themselves have a certain volume, when the upper body 100 needs to set the extreme positions for both forward and reverse rotation to correspond to a rotation angle of 180 degrees, the rigid stops themselves will occupy a certain space, causing the actual rotation angle of the upper body 100 to not reach 180 degrees, but rather to have a certain angle loss, such as 1-2 degrees. In this embodiment, by designing one of the stops as a movable limiting member 520 and movably setting the limiting member 520 in the limiting track 530, the limiting member 520 can abut against the limiting part 510 at different ends of the limiting track 530 when the upper body 100 rotates forward and reverse, thereby compensating for the aforementioned angle loss.

[0062] The second preset position can be the same as the third preset position, and the length of the limiting track 530 is just enough to compensate for the angle loss, so that the extreme positions of the upper body 100 in both forward and reverse rotation are positions with a rotation angle of 180 degrees. Alternatively, the second preset position can be close to the third preset position, and the length compensation of the limiting track 530 can be slightly larger or slightly smaller than the angle loss. In this case, there is a small angle difference between the extreme positions of the upper body 100 in both forward and reverse rotation, which can be, but is not limited to, less than 0.5 degrees. The following explanation mainly uses the example of the second preset position being the same as the third preset position.

[0063] In some embodiments, the limiting member 520 may be a sphere and roll in cooperation with the limiting track 530. When the upper body 100 rotates relative to the lower body 200 along the first direction A or the second direction B to a position near the second preset position, the limiting part 510 may push the limiting member 520 to roll along the limiting track 530.

[0064] When the limiting member 520 rolls along the first direction A to one end of the limiting track 530, as Figure 7 and Figure 9As shown, one end of the limiting track 530 will abut against the limiting member 520, preventing the limiting member 520 from rolling further along the first direction A. At this time, the limiting member 520 will abut against the limiting part 510, preventing the upper body 100 from rotating further along the first direction A. When the limiting member 520 rolls along the second direction B to the other end of the limiting track 530, as... Figure 8 and Figure 10 As shown, the other end of the limiting track 530 will abut against the limiting member 520, so that the limiting member 520 cannot roll further along the second direction B. At this time, the limiting member 520 will abut against the limiting part 510, so that the upper body 100 cannot rotate further along the second direction B.

[0065] Of course, if the limiting member 520 is at the corresponding end position of the limiting track 530 before contacting the limiting part 510, the limiting member 520 will not roll and can stop the limiting part 510 when it moves to the corresponding position.

[0066] In the above design, the limiting member 520 and the first connecting member 320 are in a separated state, and the rolling of the limiting member 520 occurs under the push of the limiting part 510. In some other embodiments, the limiting member 520 and the first connecting member 320 may also be in a contact state. In this case, when the first connecting member 320 rotates, the limiting member 520 can roll along the limiting track 530 under the drive of the first connecting member 320.

[0067] Specifically, taking the initial position of the limiting member 520 as the middle of the limiting track 530 as an example; if the upper body 100 rotates relative to the lower body 200 along the first direction A, the limiting member 520 will roll along the first direction A under the drive of the first connecting member 320. The limiting part 510 of the first connecting member 320 will also move along the first direction A. When the limiting member 520 rolls to one end of the limiting track 530, the limiting member 520 is stopped by the end of the limiting track 530 and will roll in place under the drive of the first connecting member 320 until the limiting part 510 moves to the middle of the limiting track 530. The limiting member 520 contacts the limiting member to achieve a stop and limit; if the upper body 100 rotates relative to the lower body 200 along the second direction B, the limiting member 520 will roll along the second direction B under the drive of the first connecting member 320. The limiting part 510 provided on the first connecting member 320 will also move along the second direction B. When the limiting member 520 rolls to the other end of the limiting track 530, the limiting member 520 is stopped by the end of the limiting track 530 and will roll in place under the drive of the first connecting member 320 until the limiting part 510 moves to contact the limiting member 520 to achieve a stop and limit.

[0068] In other embodiments, the limiting member 520 may also be in other shapes, such as columnar, as long as the limiting member 520 can move along the limiting track 530 and cooperate with the end of the limiting track 530 and the limiting part 510 to achieve abutment and limitation.

[0069] The limiting track 530 can be designed as any structure capable of achieving the aforementioned effects. In some embodiments, the limiting track 530 is an arc-shaped groove, with the limiting member 520 partially housed within the limiting track 530 and another portion protruding from the limiting track 530 to abut against the limiting portion 510. For example, the limiting member 520 is a sphere, with a portion of the sphere housed within the limiting track 530 and another portion protruding from the limiting track 530, so that the limiting portion 510 can abut against the protruding portion of the sphere.

[0070] In other embodiments, the limiting track 530 may also be designed in other shapes. For example, the limiting track 530 may include an arc-shaped protrusion on the surface of the second connector 330, and the surface of the limiting member 520 may have a groove that mates with the limiting track 530. Taking the limiting member 520 as a sphere as an example, the outer surface of the sphere may have an annular groove adapted to the limiting track 530, so that the sphere can roll with the limiting track 530. The limiting track 530 may also include stops at both ends for abutting the limiting member 520. It can be understood that in the embodiment where the limiting track 530 is an arc-shaped groove, the end of the limiting track 530 that abuts the limiting member 520 may be the groove wall of the arc-shaped groove or a stop protruding from the wall of the arc-shaped groove.

[0071] The following explanation mainly uses the example of the limiting track 530 being an arc-shaped groove and the limiting component 520 being a sphere.

[0072] In some embodiments, the first connecting member 320 may be provided with a first limiting groove 540, which extends along a first direction A, and the length of the first limiting groove 540 along the first direction A is greater than that of the limiting track 530. The portion of the limiting member 520 protruding from the limiting track 530 can roll in cooperation with the wall of the first limiting groove 540. Specifically, the portion of the limiting member 520 protruding from the limiting track 530 may be entirely or partially within the first limiting groove 540. When the first connecting member 320 rotates, the groove wall of the first limiting groove 540 can be used to drive the limiting member 520 to roll.

[0073] In this embodiment, by confining the protruding portion of the limiting member 520 within the first limiting groove 540, the limiting member 520 can be prevented from disengaging from the limiting track 530. The first limiting groove 540 can be configured as follows: Figure 6 The groove shown is an arc-shaped groove, and the limiting part 510 can protrude between the two ends of the first limiting groove 540. In some other embodiments, the first limiting groove 540 is an annular groove, and the limiting part 510 can protrude within the first limiting groove 540. Of course, the first connecting member 320 may not have a first limiting groove 540.

[0074] In some embodiments, the second connector 330 may be provided with a second limiting groove 550. The second limiting groove 550 is an annular groove and extends along a first direction A. A limiting track 530 may be provided on the bottom wall of the second limiting groove 550. A limiting part 510 may be inserted into the second limiting groove 550.

[0075] The limiting part 510 can be designed as any structure capable of achieving the aforementioned limiting effect, as needed. In some embodiments, the limiting part 510 can be columnar, specifically formed by a column inserted into the first connector 320, or integrally formed with the first connector 320. Its shape is, for example, but not limited to, […]. Figure 6 The cylindrical shape is shown. In other embodiments, the limiting portion 510 may also be other shapes, such as hemispherical, angular, etc.

[0076] In some embodiments, the limiting member 520 contacts the first connecting member 320, for example, in a rolling engagement with the first limiting groove 540. The groove wall of the second limiting groove 550 can be used to prevent the internal limiting member 520, limiting part 510, and other structures from being completely exposed to the outside, and can also reduce the risk of external debris entering the limiting track 530 and causing interference. In other embodiments, the limiting member 520 is separated from the first connecting member 320. The side wall of the second limiting groove 550 can also be used to prevent the limiting member 520 from detaching from the second connecting member 330. Thus, even if the limiting member 520 detaches from the limiting track 530, it will still be in the second limiting groove 550, and can then return to the limiting track 530 under the push of the limiting part 510. In other embodiments, the second limiting groove 550 may not be provided on the first connecting member 320.

[0077] It should be noted that the above description mainly uses the example of the limiting member 520 being located on the second connecting member 330. It should be understood that in other embodiments, the limiting member 520 can also be located on the first connecting member 320. In this case, the limiting portion 510 on the first connecting member 320 can be the end of the limiting track 530, and the second connecting member 330 can be provided with another stop for abutting the limiting member 520. Similarly, other structural orientations of the limiting design are not limited to the above embodiments.
