Description

Technical Field

[0001] This utility model belongs to the field of refrigeration and heating technology, and more specifically, it relates to a continuous heat release device based on solid elastic material, a seat cushion and a toilet seat cover. Background Technology

[0002] Solid-state cartridge cooling and heating is an emerging green and environmentally friendly cooling and heating technology. It involves loading or unloading solid-state cartridge materials to induce a phase change or reverse phase change, thereby generating heat or cold for cooling or heating.

[0003] Solid spring-loaded materials can be applied in everyday life, such as combining with seat cushions to release heat to the cushion. Specifically, stress is applied to the solid spring-loaded material when the cushion is pressed down, and flow cavities are set in the solid spring-loaded material. Under the action of a pump, a heat-conducting fluid is passed through, and the heat is transferred by the heat-conducting fluid to heat the cushion.

[0004] Because the pressure applied by the person pressing down on the seat cushion is instantaneous, the solid spring material is compressed instantaneously, resulting in insufficient phase change, reduced latent heat release, and short heat release time, leading to poor heating effect of the seat cushion. Utility Model Content

[0005] The purpose of this invention is to provide a continuous heat release device, a seat cushion, and a toilet seat cover based on solid elastic card material, in order to solve the technical problem of poor heat release effect caused by the instantaneous compression of solid elastic card material in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a continuous heat release device based on solid spring material, including...

[0007] Solid cartridge material;

[0008] The pressure rod, with its output end abutting against the solid spring clip material, is used to compress the solid spring clip material, causing the solid spring clip material to deform and release heat.

[0009] The force-applying component has instantaneous movement along a first direction; and

[0010] An energy storage buffer mechanism is connected to the output end of the force-applying component and the input end of the pressure rod. It is used to store the mechanical energy of the force-applying component and drive the pressure rod to slowly and continuously compress the solid elastic material body in the form of potential energy.

[0011] In one possible implementation, the energy storage buffer mechanism includes:

[0012] An energy storage unit, connected to the output end of the force-applying component, is used to store the mechanical energy of a single instantaneous movement of the force-applying component as elastic potential energy.

[0013] An energy release unit is connected between the energy storage unit and the input end of the pressure rod; and

[0014] A locking unit is used to connect to the energy release unit;

[0015] When the force-applying component moves instantaneously, the energy storage unit stores elastic potential energy, and the locking unit is connected to the energy release unit to restrict the movement of the energy release unit; when the force-applying component moves to a preset position, the locking unit and the energy release unit are unlocked, and the elastic potential energy stored in the energy storage unit drives the energy release unit to move, thereby driving the pressure rod to compress the solid elastic clip material.

[0016] In some embodiments, the energy storage unit includes:

[0017] The first torsion shell has one end face that is an open face;

[0018] A torsion elastic band, partially embedded within the first torsion outer shell; and

[0019] A first transmission structure is disposed between the output end of the force-applying member and the first torsion housing.

[0020] When the force-applying component moves along the first direction, it drives the first torsion shell to rotate through the first transmission structure, so that the torsion elastic band stores energy to the torsion.

[0021] In some embodiments, the energy release unit includes:

[0022] A second torsion housing is connected to the locking unit; one end face of the second torsion housing is an open face, and the open face of the second torsion housing is coaxially aligned with the open face of the first torsion housing; the torsion elastic band is partially embedded within the second torsion housing; and

[0023] A second transmission structure is disposed between the second torsion housing and the pressure rod;

[0024] When the locking unit and the energy release unit are released, the torsional elastic band releases energy to make the second torsional shell rotate, and drives the pressure rod to compress the solid elastic material body through the second transmission structure.

[0025] In some embodiments, the first transmission structure includes:

[0026] A first rack is disposed on the outer surface of the force-applying member, and the first rack extends along the first direction.

[0027] The first gear is disposed on the outer surface of the first torsion housing and meshes with the first rack;

[0028] The second transmission structure includes:

[0029] The second gear is disposed on the outer surface of the second torsion housing; and

[0032] In one possible implementation, the continuous heat release device based on solid spring material further includes a base; the base is provided with a contact platform, which corresponds to the force-applying member in the first direction, and a return spring is provided between the contact platform and the force-applying member.

[0035] The beneficial effects of the continuous heat release device based on solid spring-loaded material provided by this utility model are as follows: Compared with the prior art, when an instantaneous force is applied to the force-applying component, the instantaneous mechanical energy output by the force-applying component is not directly transferred to the pressure rod, but is absorbed and stored by the energy storage and buffering mechanism. The energy storage and buffering mechanism slowly and continuously releases the stored energy in the form of potential energy, driving the pressure rod to move, so that the pressure rod slowly compresses the solid spring-loaded material body, ensuring that the solid spring-loaded material body has enough time to undergo a complete and more thorough martensitic phase transformation, thereby maximizing the release of its latent heat, extending the effective heat release time, and thus improving the heating efficiency and heating stability of the device.

[0036] This utility model also provides a seat cushion, comprising:

[0037] The seat cushion itself; and

[0038] The aforementioned continuous heat release device based on solid elastic material is fixedly installed below the seat cushion body, and the input end of the force-applying component abuts against the lower surface of the seat cushion body.

[0039] The continuous heat release device based on solid elastic material further includes a sleeve, with the solid elastic material body located inside the sleeve; the sleeve contains a heat-conducting fluid, and a heat-conducting pipe is laid on the lower surface or inside of the seat cushion body, with both ends of the heat-conducting pipe being sealed and connected to the sleeve.

[0040] The seat cushion provided by this utility model, by adopting the above-mentioned continuous heat release device based on solid elastic material, can heat the seat cushion body and increase the heating time of the seat cushion body, thereby improving the comfort of use.

[0062] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0063] Please refer to the following: Figures 1 to 4The present invention provides a continuous heat release device based on solid spring-loaded material. The device comprises a solid spring-loaded material body 1, a pressure rod 2, a force-applying component 3, and an energy storage and buffering mechanism. The output end of the pressure rod 2 abuts against the solid spring-loaded material body 1, compressing it to cause deformation and heat release. The force-applying component 3 has instantaneous movement along a first direction. The energy storage and buffering mechanism connects the output end of the force-applying component 3 and the input end of the pressure rod 2, storing the mechanical energy of the force-applying component 3 and driving the pressure rod 2 to slowly and continuously compress the solid spring-loaded material body 1 through potential energy.

[0064] The solid spring-loaded elastomer is made of solid spring-loaded material, a type of functional material capable of undergoing a reversible phase transformation under mechanical stress, accompanied by significant heat absorption / release effects. Its core mechanism is the elasto-thermal effect. Specifically, when the solid spring-loaded material is compressed, an austenite-to-martensite phase transformation occurs, releasing heat; during the unloading of mechanical stress and the return to the original state from the compressed state, martensite undergoes a reverse transformation to austenite, absorbing heat. These characteristics of the solid spring-loaded material are existing technology and will not be elaborated further here. Because the solid spring-loaded elastomer is made of solid spring-loaded material, it possesses the characteristics of releasing heat upon compression and absorbing heat upon return. It should be noted that in specific applications, one end of the solid spring-loaded material body 1 is fixed, while the other end is used to contact the pressure rod 2 to ensure compression.

[0065] The force-applying component 3 serves as a power output source. Specifically, when the force-applying component 3 undergoes an instantaneous movement along the first direction, the energy storage and buffering mechanism absorbs and stores this mechanical energy, then slowly and continuously drives the pressure rod 2 to move in the form of potential energy, compressing the solid spring clip material 1, causing the solid spring clip material 1 to deform and release heat. When the force-applying component 3 moves in the opposite direction, the energy storage and buffering mechanism can again drive the pressure rod 2 to move in the opposite direction. The pressure rod 2 no longer compresses the solid spring clip material 1, and the solid spring clip material 1 returns to its original position and absorbs heat.

[0066] Compared with the prior art, the continuous heat release device based on solid spring clip material provided by this utility model does not directly transfer the instantaneous mechanical energy output by the force-applying component 3 to the pressure rod 2 when an instantaneous force is applied to the force-applying component 3. Instead, it is absorbed and stored by the energy storage and buffering mechanism. The energy storage and buffering mechanism slowly and continuously releases the stored energy in the form of potential energy, driving the pressure rod 2 to move, so that the pressure rod 2 slowly compresses the solid spring clip material body 1. This ensures that the solid spring clip material body 1 has enough time to undergo a complete and more thorough martensitic phase transformation, thereby maximizing the release of its latent heat, extending the effective heat release time, and thus improving the heating efficiency and heating stability of the device.

[0067] Specifically, the energy storage and buffer mechanism can store energy using a mechanical spring. When the force-applying component 3 is pressed down instantaneously, the spring is compressed / torsional, storing elastic potential energy. When the spring rebounds, the rebound speed is controlled by a damping device, slowly pushing the pressure rod 2. Alternatively, energy can be stored using a pneumatic or hydraulic method, with a hydraulic / pneumatic cylinder filled with oil or gas, and a piston connected to the force-applying component 3. During instantaneous pressure, the piston pushes fluid through a throttle valve into the energy storage chamber, where the fluid is compressed and stores potential energy. By adjusting the opening size of the throttle valve, the fluid return speed is controlled, allowing the piston to slowly push the pressure rod 2. Energy can also be stored using a gravity lever. The force-applying component 3 is connected to a counterweight via a lever. During instantaneous pressure, the counterweight is raised, storing gravitational potential energy. The counterweight slowly descends via a gear set or damping device, continuously applying pressure to the pressure rod 2. This embodiment does not limit the specific form of the energy storage and buffer mechanism, as long as it fulfills its function.

[0068] Preferably, the solid spring material 1 is placed in the sleeve 11, which can store heat and prevent heat loss.

[0069] This continuous heat dissipation device can be applied to a seat cushion. Located beneath the cushion, the force-applying component 3 is connected to it. When someone presses down on the cushion, a momentary force is applied to the force-applying component 3. This force-applying component 3, through an energy storage and buffering mechanism, moves the pressure rod 2 to compress the solid elastic material 1. The solid elastic material 1 releases heat and diffuses it to the lower surface of the cushion, thus heating it. When the person leaves the cushion, the force-applying component 3 can be manually returned to its original position, or it can be equipped with a return mechanism for automatic return. The force-applying component 3, through the energy storage and buffering mechanism, moves the pressure rod 2 in the opposite direction, and the pressure rod 2 no longer compresses the solid elastic material 1. The solid elastic material 1 then returns to its original position and absorbs heat. Since the person has left the cushion, even if cooling is transferred to the cushion, it does not affect its use.

[0070] In some embodiments, the above-mentioned energy storage buffer mechanism may employ, for example... Figure 2 and Figure 3 The structure shown is described in the following document. Figure 2 and Figure 3 The energy storage and buffer mechanism includes an energy storage unit 4, an energy release unit 5, and a locking unit 6. The energy storage unit 4 is connected to the output end of the force-applying component 3 and is used to store the mechanical energy of the force-applying component 3 during a single instantaneous movement as elastic potential energy. The energy release unit 5 is connected between the energy storage unit 4 and the input end of the pressure rod 2. The locking unit 6 is used to connect to the energy release unit 5.

[0071] When the force-applying component 3 moves instantaneously, the energy storage unit 4 stores elastic potential energy, and the locking unit 6 is connected to the energy release unit 5 to restrict the movement of the energy release unit 5; when the force-applying component 3 moves to the preset position, the locking unit 6 and the energy release unit 5 are unlocked, and the elastic potential energy stored in the energy storage unit 4 drives the energy release unit 5 to move, so as to drive the pressure rod 2 to compress the solid elastic clip material.

[0072] Specifically, when the force-applying component 3 moves instantaneously along the first direction, the energy storage unit 4 compresses or twists to store energy. At this time, the locking unit 6 locks, preventing the pressure rod 2 from moving. When the force-applying component 3 moves to the preset position, the locking unit 6 unlocks, and the energy release unit 5 moves slowly under the push of elastic potential energy. The pressure rod 2 continuously compresses the solid elastic material, achieving long-term heat release.

[0073] When the force-applying component 3 moves in the opposite direction as described above, the energy storage buffer mechanism can drive the pressure rod 2 to move in the opposite direction again. The pressure rod 2 no longer compresses the solid spring clip material 1, and the solid spring clip material 1 returns to its original position and absorbs heat. Alternatively, when the force-applying component 3 moves in the opposite direction as described above, the energy storage unit 4 stores energy again. At this time, the locking unit 6 locks, preventing the pressure rod 2 from moving. When the force-applying component 3 moves to the preset position of return, the locking unit 6 unlocks, and the energy release unit 5 moves slowly under the push of elastic potential energy, driving the pressure rod 2 to return to its original position. The pressure rod 2 no longer compresses the solid spring clip material 1, and the solid spring clip material 1 returns to its original position and absorbs heat.

[0074] The energy storage unit 4 stores mechanical potential energy as elastic potential energy. It converts the mechanical energy generated by the instantaneous, single movement of the force-applying component 3 into storable elastic potential energy through elastic deformation. During the operation of the locking unit 6, the stored energy is temporarily frozen to prevent immediate release. The energy release unit 5 converts the elastic potential energy into continuous mechanical energy. After the locking is released, it converts the stored elastic potential energy into slow, linear mechanical motion, driving the pressure rod 2 to move. The locking unit 6 acts as a switch for energy release. Before the force-applying component 3 moves to the preset position, it mechanically locks the energy release unit 5, preventing its movement and ensuring that the energy storage unit 4 is fully charged. When the force-applying component 3 reaches the preset position, the lock is automatically released, allowing the energy release unit 5 to begin operation.

[0075] The energy storage buffer mechanism is divided into an energy storage unit 4, an energy release unit 5, and a locking unit 6. The energy storage unit 4 solves the problem of wasted instantaneous force, efficiently storing short-term impact energy and preventing it from directly acting on the pressure bar 2, thus avoiding incomplete phase change. The energy release unit 5 extends the compression time, prolonging the phase change process of the solid spring clip material, fully releasing latent heat, and preventing sudden pressure changes from causing localized stress concentration or structural damage to the solid spring clip material 1. The locking unit 6 precisely controls the timing of the phase change, ensuring that the solid spring clip material is only compressed after energy storage is complete, avoiding energy dispersion caused by simultaneous storage and release.

[0076] In some embodiments, the energy storage unit 4 described above may employ, for example... Figure 2 and Figure 4 The structure shown is described in the following document. Figure 2 and Figure 4 The energy storage unit 4 includes a first torsional shell 41, a torsional elastic band 42, and a first transmission structure 43. One end face of the first torsional shell 41 is an open face; the torsional elastic band 42 is partially embedded in the first torsional shell 41; the first transmission structure 43 is disposed between the output end of the force-applying member 3 and the first torsional shell 41; wherein, when the force-applying member 3 moves along the first direction, it drives the first torsional shell 41 to rotate through the first transmission structure 43, so that the torsional elastic band 42 torsionalally stores energy.

[0077] Specifically, when the force-applying component 3 moves instantaneously along the first direction, it drives the first torsion shell 41 to rotate via the first transmission structure 43. Since the torsion elastic band 42 is located inside the first torsion shell 41, the rotation of the first torsion shell 41 also causes the torsion elastic band 42 to tighten and store energy. At the same time, the locking unit 6 prevents the energy release unit 5 from operating, ensuring that the energy is fully stored. When the force-applying component 3 moves to the preset position, the locking component unlocks, the torsion elastic band 42 rebounds, and the torque is slowly released via the energy release unit 5, driving the pressure rod 2 to continuously compress the solid spring clip material.

[0078] One end of the first torsional outer shell 41 is open, and the interior forms a semi-closed cavity to accommodate and constrain the torsional movement of the torsional elastic band 42, preventing the torsional elastic band 42 from radially shifting or becoming entangled when under force, thus ensuring stable energy storage. The first torsional outer shell 41 is also used to transmit rotational force. When the force-applying component 3 moves, it is driven by the first transmission structure 43 to rotate the outer shell, thereby causing the internal torsional elastic band 42 to deform and store energy.

[0079] The torsional elastic band 42 converts mechanical energy into elastic potential energy through torsional deformation. Compared to linear compression springs, torsional energy storage provides a larger deformation range and a more uniform stress distribution, making it suitable for applications with limited installation space.

[0080] The first transmission structure 43 converts the linear movement of the force-applying component 3 into the rotational motion of the first torsional shell 41, thereby driving the torsional elastic belt 42 to store energy. Compared to pure linear transmission, it can convert small-displacement linear movement into large-angle rotation, maximizing energy storage efficiency.

[0081] Specifically, the torsional elastic band 42 can be made of a highly elastic metal strip wound into a planar Archimedean spiral or a three-dimensional spiral cone, with one end fixed to the energy release unit 5 and the other end connected to the drive shaft of the first torsional housing 41. When the first torsional housing 41 rotates, the torsional elastic band 42 is wound tightly, storing elastic potential energy.

[0082] In some embodiments, the energy release unit 5 described above may employ, for example... Figure 3 and Figure 4 The structure shown is described in the following document. Figure 3 and Figure 4 The energy release unit 5 includes a second torsion shell 51 and a second transmission structure 52. The second torsion shell 51 is connected to the locking unit 6; one end face of the second torsion shell 51 is an open face, and the open face of the second torsion shell 51 is coaxially connected with the open face of the first torsion shell 41; the torsion elastic band 42 is partially embedded in the second torsion shell 51; the second transmission structure 52 is disposed between the second torsion shell 51 and the pressure rod 2; wherein, after the locking unit 6 and the energy release unit 5 are released, the torsion elastic band 42 releases energy to make the second torsion shell 51 rotate, and drives the pressure rod 2 to compress the solid elastic material through the second transmission structure 52.

[0083] The second torsion housing 51 is coaxially connected to the first torsion housing 41, together wrapping the torsion elastic band 42 to form a complete torsion cavity. This ensures the stability of the elastic band's movement trajectory during rebound and prevents the elastic band from deflecting or getting stuck during the torsion rebound process. In addition, the coaxial connection between the second torsion housing 51 and the first torsion housing 41 ensures structural sealing, preventing dust or foreign objects from entering and affecting the lifespan of the torsion elastic band 42.

[0084] The second transmission structure 52 is used to convert the rotational motion of the second torsional housing 51 into the linear motion of the pressure rod 2, directly compressing the solid spring material. By designing the transmission ratio, the rotational speed can be reduced and the output force increased, ensuring that the pressure rod 2 presses down slowly and forcefully.

[0085] In some embodiments, the first transmission structure 43 and the second transmission structure 52 described above can be adopted as follows: Figure 3 and Figure 4 The structure shown is described in the following document. Figure 3 and Figure 4 The first transmission structure 43 includes a first rack 431 and a first gear 432. The first rack 431 is disposed on the outer surface of the force-applying member 3 and extends along the first direction. The first gear 432 is disposed on the outer surface of the first torsion housing 41 and meshes with the first rack 431.

[0086] The second transmission structure 52 is similar to the first transmission structure 43, including a second gear 522 and a second rack 521. The second gear 522 is disposed on the outer surface of the second torsion housing 51; the second rack 521 is disposed on the outer surface of the pressure rod 2 and extends along the first direction, and the second rack 521 is meshed with the second gear 522.

[0087] It adopts a gear and rack drive, which has high transmission efficiency, precise motion control, and simple structure, making it easy to form with other components.

[0088] In some embodiments, the locking element described above may be as follows: Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The continuous heat release device based on solid spring card material also includes a base 7; a support cylinder 71 is provided on the base 7, and the locking unit 6 is fixed inside the support cylinder 71 and partially extends out of the support cylinder 71.

[0089] The locking unit 6 may employ an electromagnet locking pin, which includes an electromagnet and a locking pin, and the locking pin is inserted into the second torsion housing 51. Specifically, the second torsion housing 51 has a radially protruding insertion portion, and the insertion portion has an insertion hole that mates with the locking pin.

[0090] During the energy storage phase, the electromagnet is de-energized, and the locking pin is inserted into the insertion hole. When the force-applying component 3 moves to the preset position along the first direction, the electromagnet is energized, the locking pin retracts, releasing the insertion into the insertion hole, and the twisted elastic band 42 releases elastic potential energy, driving the energy release unit 5 to move. When the energy release unit 5 drives the pressure rod 2 to the preset position, that is, the compression of the solid elastic clip material 1 reaches the preset value, the insertion hole of the energy release unit 5, i.e., the second twisted outer shell 51, rotates to correspond with the locking unit 6. Then the electromagnet is de-energized, and the locking pin is inserted into the insertion hole again.

[0091] When the external force of the force-applying component 3 is removed, and the force-applying component 3 moves in the opposite direction as described above, the torsional elastic band 42 is stretched in the opposite direction and stores energy again. At this time, the electromagnet is de-energized, and the locking pin is inserted into the insertion hole to prevent the pressure rod 2 from moving. When the force-applying component 3 moves to the preset return position, the locking unit 6 is unlocked, the electromagnet is energized, the locking pin retracts, and the insertion with the insertion hole is released. The torsional elastic band 42 releases elastic potential energy, and the energy release unit 5 rotates slowly under the push of the elastic potential energy, driving the pressure rod 2 back to its original position. The pressure rod 2 no longer compresses the solid spring clip material 1, and the solid spring clip material 1 returns to its original position and absorbs heat.

[0092] Because the torsional elastic band 42 is made of a highly elastic metal strip wound into a planar Archimedean spiral or a three-dimensional spiral cone, it can generate elasticity and store energy whether it is stretched in the forward or reverse direction.

[0093] It should be noted that the movement position of the force-applying component 3 can be detected by a distance sensor or a pressure sensor. Both the sensor and the locking unit 6 are electrically connected to the controller. When the sensor detects that the force-applying component 3 has moved to a preset position, the controller controls the electromagnet to be energized to release the lock.

[0094] The base 7 is used to support the fixing sleeve 11, and the support cylinder 71 is used to support the fixing locking unit 6. The position of the locking unit 6 can be raised using the support cylinder 71 to adapt to the connection with the energy release unit 5. It should be noted that in specific applications, the base 7 is fixed, so the sleeve 11 is also fixed. The solid spring clip material 1 is confined inside the sleeve 11 so that it can be compressed and release heat.

[0095] In some embodiments, the base 7 described above may also be as follows: Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The base 7 is provided with a contact platform 72. In the first direction, the contact platform 72 is directly opposite to the force-applying member 3. A return spring 73 is also provided between the contact platform 72 and the force-applying member 3.

[0096] The contact platform 72 is used to limit the movement of the force-applying component 3 along the first direction. When the force-applying component 3 moves instantaneously to abut against the contact platform 72, it is limited by the contact platform 72 and cannot move again. That is to say, the preset position of the force-applying component 3 is the position where it abuts against the contact platform 72. Specifically, a pressure sensor can be installed on the contact platform 72 to monitor whether the force-applying component 3 abuts against the contact platform 72. When the controller receives a value monitored by the pressure sensor that is greater than or equal to a preset value, the controller controls the electromagnet of the locking unit 6 to be energized, the locking pin retracts, and the insertion with the second torsion housing 51 is released.

[0097] The return spring 73 is disposed between the contact table 72 and the force-applying component 3, such as Figure 2 and Figure 3 As shown, one end of the spring is sleeved on the contact platform 72, and the other end is sleeved on the force-applying component 3, which is used to drive the force-applying component 3 to return to its original position. Specifically, when the force-applying component 3 is subjected to force and moves in the first direction, the return spring 73 is compressed. When the external force disappears, the return spring 73 returns to its original position and drives the force-applying component 3 to move in the opposite direction of the first direction, so that the force-applying component 3 returns to its original position.

[0098] A return spring 73 is installed between the contact table 72 and the force-applying component 3, eliminating the need for external operation to return the force-applying component 3 to its original position, thus simplifying the operation process.

[0099] In some embodiments, the above-described continuous heat release device may also employ, for example... Figure 1 and Figure 4 The structure shown is described in the following document. Figure 1 and Figure 4The continuous heat release device also includes a cover 8, which covers the solid elastic material body 1, the pressure rod 2, the force application member 3 and the energy storage buffer mechanism. The cover 8 is provided with a first slide and a second slide. The force application member 3 is slidably disposed in the first slide, and the input end of the force application member 3 extends out of the cover 8. The pressure rod 2 is slidably disposed in the second slide.

[0100] The cover 8 serves as an integrated outer shell, providing protection for the heating structure, pressure rod 2, force application component 3, and energy storage buffer mechanism. It isolates dust, liquid, and other contaminants from entering the sleeve 11 or the energy storage buffer mechanism, extending the life of the components. It also prevents pinching or mechanical damage caused by users accidentally touching moving parts.

[0101] The cover 8 is also equipped with a first slide and a second slide to restrict the sliding of the force-applying component 3 and the pressure rod 2. The first slide constrains the linear motion trajectory of the force-applying component 3, ensuring that it moves strictly along the first direction, avoiding mis-triggered or non-triggered locking unit 6 or uneven torsion of energy storage unit 4 caused by skewness. The second slide guides the linear motion of the pressure rod 2, making it accurately aligned with the solid spring clip material 1, preventing lateral friction loss or uneven distribution of compressive force.

[0102] It should be noted that the first slide rail and the force-applying component 3, and the second slide rail and the pressure rod 2 can both adopt a low-friction design to reduce the motion resistance of the force-applying component 3 and the pressure rod 2, and ensure that the input mechanical energy is maximized to be converted into elastic potential energy.

[0103] Please see Figure 5 Based on the same inventive concept, this application also provides a seat cushion, including a seat cushion body 9 and the above-mentioned continuous heat release device based on solid elastic material. The continuous heat release device is fixedly disposed below the seat cushion body 9, and the input end of the force application member 3 abuts against the lower surface of the seat cushion body 9.

[0104] When a person sits on the seat cushion body 9, their own weight presses down on the seat cushion body 9, simultaneously applying a momentary force to the force-applying component 3. The force-applying component 3, through an energy storage and buffering mechanism, drives the pressure rod 2 to move, compressing the solid spring material 1. The solid spring material 1 releases heat and diffuses the heat to the lower surface of the seat cushion, thus heating the cushion. When the person leaves the seat cushion, the force-applying component 3 can be manually returned to its original position, or the return spring 73 can automatically return the force-applying component 3 to its original position. The force-applying component 3, through the energy storage and buffering mechanism, drives the pressure rod 2 to move in the opposite direction, and the pressure rod 2 no longer compresses the solid spring material 1. The solid spring material 1 returns to its original position and absorbs heat. Since the person has left the seat cushion, even if cold air is transferred to the seat cushion, it does not affect its use.

[0105] The seat cushion provided by this utility model, due to the adoption of the above-mentioned continuous heat release device based on solid elastic material, when the seat cushion is pressed down, the instantaneous mechanical energy output by the force-applying component 3 is not directly transferred to the pressure rod 2, but is absorbed and stored by the energy storage and buffer mechanism. The energy storage and buffer mechanism slowly and continuously releases the stored energy in the form of potential energy, driving the pressure rod 2 to move and causing the pressure rod 2 to slowly compress the solid elastic material body 1, ensuring that the solid elastic material body 1 has enough time to undergo a complete and more thorough martensitic phase transformation, thereby maximizing the release of its latent heat, extending the effective heat release time, increasing the heating time of the seat cushion body 9, and improving the comfort of use.

[0106] Specifically, a heat insulation cover 8 can be installed below the seat cushion body 9, and the aforementioned continuous heat release device can be placed inside the heat insulation cover 8. The heat released by the compression of the solid elastic material 1 is stored in the inner cavity of the heat insulation cover 8 and transferred to the seat cushion body 9. Alternatively, a heat conduction pipe 91 can be installed below the seat cushion body 9 to transfer heat.

[0107] In some embodiments, the above-described continuous heat dissipation device can transfer heat to the cushion body 9 in the following manner: Figure 5 The structure shown is described in the following document. Figure 5 The continuous heat release device also includes a sleeve 11, and a fixing spring clip material is placed inside the sleeve 11; the sleeve 11 contains a heat-conducting fluid, and a heat-conducting pipe 91 is laid under the seat body 9, with both ends of the heat-conducting pipe 91 being sealed and connected to the sleeve 11 respectively.

[0108] Specifically, the sleeve 11 is provided with an inlet 111 and an outlet 112. One end of the heat-conducting pipe 91 is connected to the inlet 111, and the other end is connected to the outlet 112. The heat-conducting pipe 91 is coiled and arranged on the lower surface of the cushion body 9. The heat-conducting pipe 91 is also connected to a pump unit.

[0109] The heat released when the solid elastic material 1 is compressed is rapidly absorbed by the heat-conducting fluid in direct contact. Driven by the pump unit, the heat-conducting fluid circulates within the heat-conducting pipe 91 to heat the seat cushion body 9. The spirally arranged heat-conducting pipe 91 can cover the lower surface of the seat cushion body 9, eliminating the problem of uneven heating and cooling.

[0110] The cushion provided in this embodiment uses the weight of the human body to apply pressure to the solid elastic material 1, causing it to generate heat, which is then conducted to the cushion body 9 to make it heat up. When the person gets up, the force-applying component 3, the energy storage buffer mechanism, and the pressure rod 2 automatically return to their original positions, and the solid elastic material 1 returns to its original position and unloads, generating cooling energy, which cools the cushion body 9.

[0111] The cushion provided in this embodiment can be applied to cushions that require short-term heating, such as toilet cushions and public transportation cushions for short distances. That is, when a person sits down, the cushion body 9 heats up, and after leaving, the cushion body cools down.

[0112] Based on the same inventive concept, this application also provides a toilet seat, including a toilet seat body and the above-mentioned continuous heat release device based on solid elastic material, which is fixedly disposed below the toilet seat body, and the input end of the force application member 3 can abut against the lower surface of the toilet seat body.

[0113] The continuous heat release device based on solid elastic card material further includes a sleeve 11, the solid elastic card material body 1 is located inside the sleeve 11; the sleeve 11 contains a heat-conducting fluid, and a heat-conducting pipe 91 is laid on the lower surface or inside of the toilet seat body, and the two ends of the heat-conducting pipe 91 are respectively sealed and connected to the sleeve 11.

[0114] The toilet seat in this embodiment shares the same basic concept as the aforementioned seat cushion, differing only in its application. While the continuous heat dissipation device in the aforementioned embodiment was applied to the seat cushion, this embodiment applies it to the toilet seat. This toilet seat has the same effect as the aforementioned seat cushion, which will not be elaborated upon further here.

[0115] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
