Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and more particularly to a cold or hot compress device and a method for using the same. Background Art

[0002] In medical rehabilitation and daily life care scenarios, hot and cold compress therapy is a common physical therapy method.

[0003] For some complex sports injuries, such as when an athlete suffers a sprain and strain at the same time during a game, the injured part may need cold compresses to urgently treat the acute injury and reduce swelling and pain in a short period of time, and it may also need to switch to hot compresses at the appropriate time to promote local blood circulation and speed up the repair of damaged tissues. In this case, accurate and timely switching between hot and cold compresses is crucial to the recovery process.

[0004] For example, in the treatment of scalds or burns, using cold compresses in the early stage can reduce the temperature of the injured area, reduce further damage to the tissue by heat, and relieve pain; while when the wound enters the healing stage, appropriate hot compresses can help promote local metabolism and accelerate wound healing. At this time, switching between hot and cold compresses according to the recovery stage of the wound can effectively improve the treatment effect.

[0005] During the medical rehabilitation process, for some patients with long-term illnesses, such as rheumatoid arthritis patients, joint symptoms vary at different times. During the inflammation period, cold compresses can help reduce joint redness, swelling, heat and pain; while during the remission period, hot compresses can improve blood circulation in the joints, reduce joint stiffness, and increase joint mobility. Frequent and precise switching between hot and cold compresses can better relieve patients' symptoms and improve their quality of life.

[0006] Not only that, in some special cases, the hot and cold compress device is also required to switch between hot and cold water quickly. For example, at the scene of an accidental injury, such as a traffic accident or outdoor sports injury, the injured may need to apply cold compress immediately to control the deterioration of the injury, but as the rescue time goes by and the injury changes, it may be necessary to switch to hot compress as soon as possible to promote recovery. In such an urgent and complex situation, if the hot and cold compress device can achieve rapid switching between hot and cold water, it can provide more effective treatment for the injured at the first time.

[0007] Another example is in some beauty care scenarios, for example, cold compress on the face can shrink pores and reduce oil secretion on the skin, while hot compress can help promote the absorption of skin care products and enhance the skin care effect. In a complete facial care process, it is necessary to quickly switch between hot and cold compress modes to improve care efficiency and effectiveness. However, existing beauty hot and cold compress equipment often cannot meet this demand for fast switching, which affects the quality of beauty care.

[0008] Traditional hot and cold compress devices often separate the cold water and hot water circulation pipelines and equip them with water pumps, which makes the device structure complicated and increases the cost. Multiple circulation pipelines not only take up space, but also increase the risk of device failure, making repair and maintenance more difficult. For example, in some large hot and cold compress devices used in hospitals, due to the large number of circulation pipelines, once a pipeline is blocked or leaking, the troubleshooting and repair work is time-consuming and labor-intensive, seriously affecting the normal use of the equipment.

[0009] Moreover, existing hot and cold compress devices are not convenient and efficient enough in switching between hot and cold water. In actual use, users need to frequently manually operate multiple valves or switches to achieve the conversion of hot and cold compress modes, which is cumbersome and error-prone. For example, when users switch between hot and cold compress functions in some household hot and cold compress products, the hot and cold water are often mixed due to the complicated operation steps, which affects the use effect and may even cause safety hazards such as burns or frostbite to the user.

[0021] The present invention has at least the following beneficial effects: The present invention adopts a unique multi-cavity structure, and realizes the circulation of hot and cold water only through a set of circulation pipelines connected to the buffer chamber, abandoning the complex design of the traditional hot and cold compress device in which the cold water and hot water circulation pipelines are separately set and equipped with water pumps respectively. This greatly simplifies the device structure, reduces the number of parts, and thus reduces the production cost.

[0022] The ingenious coordination between the movable plate and the pressing blocks of the present invention, as well as the reasonable layout of the openings, realizes the precise control of the supply and switching of hot and cold water. During the cold compress, hot compress and hot and cold switching process, the various components work together according to the predetermined logic, effectively avoiding the cross-flow phenomenon of hot and cold water, and ensuring the reliability and stability of the operation of the device. The bottom and top of the buffer chamber of the present invention are respectively provided with a base and a top seat. The movable plate fits with the base and the top seat when in different positions, and the pressing blocks are inserted into the corresponding openings, which provides clear upper and lower limit positions for the movable plate and plays a role in precise positioning. This not only ensures that the hot and cold compress device transports cold water or hot water according to the design logic, but also enhances the overall structural stability of the device, reduces the shaking and displacement of the movable plate during movement, reduces component wear, and extends the service life of the device.

[0023] The cold water chamber, hot water chamber and buffer chamber of the present invention are divided into two parts, so that the storage and mixing functions of cold and hot water are separated. The buffer chamber is used as a mixing and temporary storage space for cold and hot water. Through the connection with the cold water chamber and the hot water chamber and the water circulation of the compress bag, the switching of the cold and hot compress functions is realized. This design ensures the stability and continuity of the cold and hot water supply, avoids the direct mixing of cold and hot water, and improves the effect and safety of the cold and hot compress.

[0024] The first opening, the second opening, and the third opening of the present invention respectively play the key role of guiding hot and cold water into or out of the cache chamber in different working modes. The first opening is precisely opened during cold compress to provide a stable cold source for cold compress; the third opening assists the first opening during cold compress to accelerate the flow of cold water in the cache chamber, making the water temperature uniform and improving the cold compress effect, and discharges the cold water remaining above the cache chamber during hot compress; the second opening is opened during hot compress to provide suitable hot water for hot compress. The coordinated work of these openings ensures that hot and cold water flow into the cache chamber according to design requirements at different stages, and then flow to the compress bag, achieving precise water flow control.

[0025] The power device of the present invention drives the moving plate to move up and down, and cooperates with the functions of each pressing block and the first elastic member and the second elastic member to realize fast and convenient switching of hot and cold compress modes.

[0026] The automatic hot and cold water switching design of the present invention eliminates the need for users to frequently manually operate multiple valves or switches as in traditional devices, which reduces the difficulty of operation and the probability of errors caused by cumbersome operations. Users only need to start the power device to perform operations such as cold compress, hot compress, and hot and cold switching, which improves the convenience of use.

[0027] The temperature sensors embedded on the top and bottom of the movable plate of the present invention can monitor the temperature of hot and cold water in real time, providing data basis for accurate control of water temperature. By cooperating with other control components, the temperature of hot and cold water can be adjusted in time to meet the personalized temperature requirements of different users, thereby improving the effect and comfort of hot and cold compress treatment.

[0033] Design purpose and beneficial effects of each part: Cold water room 1, hot water room 2 and cache room 3: Design purpose: Cold water chamber 1 is used to store low-temperature cold water to provide a stable cold source for cold compress; hot water chamber 2 is used to store hot water to meet the demand for suitable water temperature during hot compress; buffer chamber 3 is used as a mixing and temporary storage space for hot and cold water. Through the connection with cold water chamber 1 and hot water chamber 2 and the water circulation of the compress bag, the switching of hot and cold compress functions can be realized. In actual use, the functions of cold water chamber 1 and hot water chamber 2 can be interchangeable, as long as one of them provides cold water and the other provides hot water.

[0034] Beneficial effects: This multi-cavity design separates the storage and mixing functions of hot and cold water, so that the device can meet the different needs of cold and hot compresses respectively. Through the transition of the buffer chamber 3, the stability and continuity of the supply of hot and cold water are ensured, the direct mixing of hot and cold water is avoided, and the effect and safety of hot and cold compresses are improved.

[0035] The first opening 301, the second opening 302 and the third opening 303: Design purpose: The first opening 301 and the third opening 303 are connected to the cold water chamber 1. The first opening 301 allows cold water to flow into the cache chamber 3 during cold compress to provide a cold source for cold compress; the third opening 303 assists the first opening 301 during cold compress to ensure that cold water can quickly and evenly fill the corresponding area of ​​the cache chamber 3, and discharge the cold water remaining above the cache chamber 3 during hot compress. The second opening 302 is connected to the hot water chamber 2, allowing hot water to flow into the cache chamber 3 during hot compress to provide a heat source for hot compress, and discharge the hot water remaining below the cache chamber 3 during cold compress. They are channels for cold and hot water to enter or discharge the cache chamber 3 in different working modes.

[0036] Beneficial effects: The first opening 301 is precisely opened during cold compress to ensure timely inflow of cold water, providing a stable cold source for cold compress. The third opening 303 cooperates with the first opening 301 during cold compress to accelerate the flow of cold water in the buffer chamber 3, making the water temperature in the buffer chamber 3 uniform and improving the cold compress effect; during hot compress, the third opening 303 discharges the cold water remaining above the buffer chamber 3 back to the cold water chamber 1, avoiding the mixing of cold and hot water, ensuring the stability of the hot water temperature during hot compress and the effectiveness of the hot compress effect. The second opening 302 is opened during hot compress to allow hot water to flow smoothly into the buffer chamber 3, providing suitable hot water for hot compress and ensuring the normal operation of the hot compress function.

[0037] The fourth opening, the first elastic member 32 and the second pressing block 34: Design purpose: The fourth opening provides a movable space for the second pressing block 34. The first elastic member 32 is connected to the second pressing block 34 so that it maintains a certain position when not squeezed. When the first pressing block 33 squeezes the second pressing block 34, the second pressing block 34 can move in the fourth opening, thereby controlling the opening and closing of the first opening 301.

[0038] Beneficial effects: This design achieves precise control of the first opening 301 through the cooperation of the first pressing block 33 and the second pressing block 34. During cold compress, the first pressing block 33 squeezes the second pressing block 34 to open the first opening 301, allowing cold water to flow smoothly into the buffer chamber 3; during hot compress, the second pressing block 34 resets and seals the first opening 301 to prevent cold water from flowing in, ensuring the normal switching of the hot and cold compress modes and improving the working efficiency of the device.

[0039] Mobile plate 31 and power device: Design purpose: The moving plate 31 moves up and down under the drive of the power device, and cooperates with the first pressing block 33, the second pressing block 34 and other components to block and guide the water flow, control the opening and closing of each opening, and realize the supply and switching of hot and cold water. The power device provides power for the movement of the moving plate 31.

[0040] Beneficial effect: The coordinated work of the moving plate 31 and the power device enables the hot and cold compress device to realize automatic switching of hot and cold water. Precise movement control ensures that each opening is opened or closed according to predetermined requirements in different working modes, improves the operating convenience and stability of the device, and reduces the operating difficulty of the user.

[0041] The first pressing block 33 and the second pressing block 34: Design purpose: The first pressing block 33 is installed at the bottom of the movable plate 31, and is opposite to the second pressing block 34 up and down. The interaction between the two controls the opening and closing of the first opening 301, thereby controlling the inflow and blocking of cold water.

[0042] Beneficial effects: Their design ensures precise control of cold water supply. During cold compress, the first pressing block 33 squeezes the second pressing block 34 to open the first opening 301, ensuring that cold water enters the buffer chamber 3 smoothly; in other modes, the second pressing block 34 can effectively seal the first opening 301 to prevent cold water from flowing accidentally, thereby improving the sealing and reliability of the device in different working modes.

[0043] Water inlet 304 and water outlet 305: Design purpose: As the key interface for water circulation in the device, the water outlet 305 transports the water in the buffer chamber 3 to the compress bag, and the water inlet 304 returns the water in the compress bag to the buffer chamber 3, thereby realizing the circulation of cold and hot water between the compress bag and the buffer chamber 3.

[0044] Beneficial effects: It ensures that hot and cold water can be supplied to the compress bag in a timely and stable manner, maintaining the continuation of cold or hot compress. This circulation design improves the utilization efficiency of hot and cold water, ensures the continuity of the cold and hot compress effect, and provides users with a better experience.

[0045] When the movable plate 31 moves downward from the second position until the top of the first pressing block 33 is flush with the top of the first opening 301, the first opening 301 is sealed by the second pressing block 34 and / or the first pressing block 33: Design purpose: to ensure that the water in the cold water chamber 1 and the hot water chamber 2 will not flow in parallel during the switching process between cold and hot compresses, to ensure that the device provides cold water or hot water to the compress bag in a predetermined manner, and to maintain the independence and stability of the cold and hot compress functions. During the switching process, the water flow path is precisely controlled so that only when the moving plate 31 reaches a specific position, the corresponding opening will be opened or closed, so that cold water and hot water can flow into the buffer chamber 3 according to the design requirements at different stages, and then flow to the compress bag.

[0046] Beneficial effect: It effectively avoids the mixing of cold water and hot water caused by the first opening 301 not being sealed in time, makes the switching of cold compress and hot compress functions more accurate and reliable, and can provide users with a stable cold compress or hot compress experience.

[0047] The method of using the hot and cold compress device provided in this scheme is as follows: 1. Cold compress operation Preparation: Ensure that there is enough cold water in the cold water chamber 1 and that all parts of the device are in normal working condition.

[0048] Start cold compress: Start the power device to drive the moving plate 31 downward to the first position. During the movement, the first pressing block 33 at the bottom of the moving plate 31 moves downward synchronously to squeeze the second pressing block 34. After being squeezed, the second pressing block 34 moves downward, and then the moving plate 31 moves downward to the bottom of the first opening 301 and seals the second opening 302. At this time, the first opening 301 is open, and the water inlet 304 and the water outlet 305 are both located above the moving plate 31.

[0049] Cold compress: The cold water in the cold water chamber 1 flows rapidly into the area above the movable plate 31 in the buffer chamber 3 through the first opening 301 under the action of the pressure difference. The cold water flows into the compress bag through the water outlet 305, contacts the part that needs cold compress, absorbs heat, and then flows back to the buffer chamber 3 through the water inlet 304, forming a stable cycle, continuously supplying cold water to the compress bag, and realizing the cold compress function.

[0050] 2. Hot compress operation Preparation: Ensure that hot water of suitable temperature is stored in the hot water chamber 2 and that all components of the device operate normally.

[0051] Start hot compress: Start the power device to drive the movable plate 31 from the first position to the second position. As the movable plate 31 rises, the second pressing block 34 gradually returns to its original position under the elastic force of the first elastic member 32, and its upper part is located outside the fourth opening, re-blocking the first opening 301. At the same time, the movable plate 31 rises above the second opening 302, so that the second opening 302 is opened. When the movable plate 31 moves to the second position, the movable plate 31 is located below the third opening 303 or blocks the third opening 303, which can prevent hot water from flowing from the third opening 303 to the cold water chamber 1.

[0052] Hot compress: The hot water in the hot water chamber 2 enters the area below the movable plate 31 in the buffer chamber 3 through the second opening 302 under its own pressure. The hot water forms a cycle through the water inlet 304 and the water outlet 305, flows into the compress bag to provide heat to the part that needs hot compress, and realizes the hot compress function.

[0053] 3. Switch from cold to hot compress Preparation: When it is determined that it is necessary to switch from cold compress to hot compress, first check whether the hot water temperature in the hot water chamber 2 reaches the standard range suitable for hot compress.

[0054] Start switching: first, let the cold water in the compress bag flow back to the buffer chamber 3, then turn on the power device to drive the moving plate 31 upward. As the moving plate 31 rises, the first pressing block 33 that originally squeezed the second pressing block 34 gradually breaks away from the second pressing block 34. Due to the action of the first elastic member 32, the second pressing block 34 begins to reset, and its upper part gradually moves outward from the fourth opening until it re-blocks the first opening 301, effectively preventing the cold water in the cold water chamber 1 from continuing to flow into the buffer chamber 3.

[0055] Cold water discharge: The moving plate 31 continues to move upward, and at this time it pushes the cold water above it in the buffer chamber 3 to move upward. Since the third opening 303 is connected to the cold water chamber 1 and the position is reasonably designed, under the push of the moving plate 31, the cold water above the moving plate 31 flows smoothly back to the cold water chamber 1 through the third opening 303. This process avoids a large amount of cold water remaining in the buffer chamber 3.

[0056] Start hot compress: When the movable plate 31 rises to the second position, the movable plate 31 is located above the second opening 302, the water inlet 304 and the water outlet 305. At this time, the movable plate 31 has completely left the position of the second opening 302, so that the second opening 302 is open. Under the action of its own pressure, the hot water in the hot water chamber 2 flows into the area below the movable plate 31 in the cache chamber 3 through the second opening 302. The hot water forms a cycle through the water inlet 304 and the water outlet 305, and flows into the compress bag to provide heat to the part that needs hot compress, realizing the hot compress function, and thus completing the switch from cold compress to hot compress.

[0057] 4. Switch from hot to cold compress Preparation: When the hot compress achieves the desired effect and you are ready to switch to cold compress, make sure there is sufficient low-temperature cold water in the cold water chamber 1.

[0058] Start switching: first, the hot water in the compress bag flows back to the buffer chamber 3, and then the power device is started to drive the moving plate 31 downward. As the moving plate 31 descends, the second pressing block 34 that originally sealed the first opening 301 is gradually squeezed by the first pressing block 33 at the bottom of the moving plate 31. Under the squeezing force, the upper part of the second pressing block 34 gradually moves into the fourth opening.

[0059] Draining hot water: The moving plate 31 continues to move downward and starts to push the hot water in the buffer chamber 3 below it downward. Since the second opening 302 is connected to the hot water chamber 2, the hot water below the buffer chamber 3 flows back to the hot water chamber 2 through the second opening 302 under the push of the moving plate 31.

[0060] Turn on the cold compress: When the movable plate 31 moves downward to the first position, the first pressing block 33 completely squeezes the second pressing block 34 into the fourth opening, so that the first opening 301 is opened. At the same time, the movable plate 31 seals the second opening 302. At this time, the water inlet 304 and the water outlet 305 are both located above the movable plate 31. Under the action of the pressure difference, the cold water in the cold water chamber 1 quickly flows into the area above the movable plate 31 in the cache chamber 3 through the first opening 301. The cold water flows into the compress bag through the water outlet 305, contacts the part that needs cold compress, absorbs heat, and then flows back to the cache chamber 3 through the water inlet 304, forming a stable cycle, realizing the cold compress function, and completing the switch from hot compress to cold compress.

[0061] In another embodiment, in the hot and cold compress device, the bottom of the cold water chamber 1 is higher than the bottom of the hot water chamber 2 , the first opening 301 is close to the bottom of the cold water chamber 1 , and the second opening 302 is close to the bottom of the hot water chamber 2 .

[0062] The bottom of the cold water chamber 1 is set higher than the bottom of the hot water chamber 2, and the first opening 301 is close to the bottom of the cold water chamber 1, and the second opening 302 is close to the bottom of the hot water chamber 2. During cold compress, cold water can flow more smoothly from the cold water chamber 1 through the first opening 301 into the cache chamber 3 under the action of gravity; during hot compress, hot water can also flow efficiently from the hot water chamber 2 through the second opening 302 into the cache chamber 3 under the action of gravity. This allows the cold and hot water to flow more smoothly under the action of gravity, reduces energy loss, improves the efficiency and stability of the cold and hot water supply, and further optimizes the performance of the device. In another embodiment, in the cold and hot compress device, Figures 1 to 3As shown, a third pressing block 35 is installed on the top of the movable plate 31; a fifth opening is provided on the top of the cache chamber 3 in the vertical direction, a second elastic member 36 is provided in the fifth opening, a fourth pressing block 37 is connected to the bottom of the second elastic member 36, the upper part of the fourth pressing block 37 is always inserted into the fifth opening, and the fourth pressing block 37 is opposite to the third pressing block 35 in the upper and lower parts; the power device can drive the movable plate 31 to move upward from the first position to the third position, and then move upward from the third position to the second position; as shown Figure 1 As shown, when the movable plate 31 is located at the first position, the fourth pressing block 37 seals the third opening 303, and the third pressing block 35 does not seal the first opening 301. At this time, although the third pressing block 35 is opposite to the first opening 301, it does not seal the first opening 301, so that cold water can enter the cache chamber 3 through the first opening 301; Figure 2 As shown, when the movable plate 31 is located at the second position, the movable plate 31 seals the third opening 303; Figure 3 As shown, when the movable plate 31 is located at the third position, the first pressing block 33 and the third pressing block 35 are only in contact with the second pressing block 34 and the fourth pressing block 37 respectively, and the upper part of the second pressing block 34 is located outside the fourth opening, and the lower part of the fourth pressing block 37 is located outside the fifth opening, the first opening 301 is closed by the second pressing block 34, and the third opening 303 is closed by the fourth pressing block 37, the water inlet 304, the water outlet 305 and the third opening 303 are all located above the movable plate 31, and the first opening 301 and the second opening 302 are all located below the movable plate 31; when the third pressing block 35 is opposite to the third opening 303, the third pressing block 35 does not seal the third opening 303, so that the third pressing block 35 will not seal the third opening 303 in the process of pushing the fourth pressing block 37 upward, and then when the movable plate 31 pushes the cold water thereon upward, the cold water can flow back to the cold water chamber 1 through the third opening 303.

[0063] In actual use, the liquid level of cold water in the cold water chamber 1 can be made lower than the height of the third opening 303, so that when the third opening 303 is not closed, cold water cannot enter the cache chamber 3 through the third opening 303. However, in actual use, due to factors such as slight shaking of the device and changes in the placement angle, cold water may flow into the cache chamber 3 over the third opening 303. This part of water cannot be cooled by the refrigeration component, affecting the use of the device. When the device is not in use, the movable plate 31 can be kept in the third position. At this time, the fourth pressing block 37 can prevent cold water from entering the area above the movable plate 31 in the cache chamber 3 when the device is slightly shaken. Because the second opening 302 is connected to the hot water chamber 2, only a small amount of hot water remains in the cache chamber 3.

[0064] The method of using the hot and cold compress device provided in this scheme is as follows: 1. How to use cold compress: Preparation: Check the cold water chamber 1 to ensure that there is sufficient low-temperature cold water stored. The water temperature should meet the cold compress requirements (generally recommended to be around 0-10℃, which can be adjusted according to actual usage scenarios and needs).

[0065] Start the cold compress process: The power device is turned on, and the power device drives the moving plate 31 downward. During the downward process, the first pressing block 33 at the bottom of the moving plate 31 moves downward synchronously.

[0066] As the moving plate 31 moves downward, the first pressing block 33 gradually approaches and presses the second pressing block 34. After the second pressing block 34 is pressed, its upper portion is further fully inserted into the fourth opening. This action opens the first opening 301, and at the same time, the moving plate 31 moves downward to below the first opening 301, sealing the second opening 302. At this time, the water inlet 304 and the water outlet 305 are both located above the moving plate 31.

[0067] Cold compress implementation stage: The cold water in the cold water chamber 1 flows rapidly into the area above the movable plate 31 in the cache chamber 3 through the first opening 301 under the action of pressure difference (mainly gravity and the spatial pressure difference in the device).

[0068] Cold water flows into the compress bag through the water outlet 305 and contacts the part that needs cold compress. During the contact process, the cold water absorbs the heat of the injured part, thereby reducing the local temperature, reducing swelling and pain. The cold water after absorbing the heat flows back to the buffer chamber 3 through the water inlet 304, forming a stable cycle.

[0069] 2. How to use hot compress: Preparation: Check the hot water chamber 2 to ensure that there is enough hot water stored. The water temperature should reach a temperature range suitable for hot compress (usually recommended to be around 40 - 50°C, which can be adjusted according to actual usage needs).

[0070] To start the hot compress operation: The power device is started to drive the moving plate 31 upward from the first position. As the moving plate 31 rises, the second pressing block 34 is gradually reset under the elastic force of the first elastic member 32. Its upper portion gradually moves upward from the fourth opening until the upper portion of the second pressing block 34 is located outside the fourth opening. At this time, the second pressing block 34 blocks the first opening 301 again to prevent cold water from flowing into the buffer chamber 3.

[0071] The movable plate 31 continues to move upward, and when it reaches the third position, the third pressing block 35 contacts the fourth pressing block 37 and starts to press the fourth pressing block 37 , and the movable plate 31 is located above the second opening 302 , so that the second opening 302 is opened.

[0072] The power device continues to drive the moving plate 31 upward to the second position. At this time, the moving plate 31 seals the third opening 303.

[0073] Hot compress stage: The hot water in the hot water chamber 2 enters the area below the movable plate 31 in the cache chamber 3 through the second opening 302 under the action of its own pressure (mainly gravity and the spatial pressure difference in the device).

[0074] The hot water flows into the compress bag through the water outlet 305, contacts the part that needs hot compress, provides heat to the part, promotes blood circulation, relieves muscle fatigue and joint pain. After absorbing the heat of the human body, the hot water flows back to the buffer chamber 3 through the water inlet 304, forming a stable cycle to maintain the hot compress effect.

[0075] 3. How to use cold compress to switch to hot compress Prepare to switch: Make sure the hot water required for hot compress is ready and the water temperature meets the requirements.

[0076] Start the switching operation: First, the cold water in the compress bag flows back to the buffer chamber 3, and then the power device is started to drive the moving plate 31 upward. As the moving plate 31 rises, the first pressing block 33 and the second pressing block 34 gradually disengage from the squeeze, and the second pressing block 34 is reset under the action of the first elastic member 32, and its upper part moves outward from the fourth opening, re-closing the first opening 301 and blocking the inflow of cold water. At the same time, the moving plate 31 gradually moves to the top of the second opening 302 and opens the second opening 302.

[0077] The movable plate 31 continues to move upward, and when it reaches the third position, the third pressing block 35 starts to press the fourth pressing block 37 .

[0078] The movable plate 31 continues to move upward to the second position. During this process, the movable plate 31 gradually seals the third opening 303 .

[0079] Complete the switch: The hot water in the hot water chamber 2 flows into the buffer chamber 3 through the second opening 302 and enters the compress bag to achieve hot compress, completing the switch from cold compress to hot compress.

[0080] 4. How to use hot compress to switch to cold compress Prepare to switch: Confirm that there is enough cold water in the cold water chamber 1 and the water temperature meets the cold compress requirements.

[0081] Start the switching process: First, the hot water in the compress bag flows back to the buffer chamber 3, and then the power device is started to drive the movable plate 31 downward. As the movable plate 31 descends, the third pressing block 35 and the fourth pressing block 37 gradually disengage from being squeezed, and the fourth pressing block 37 is reset under the action of the second elastic member 36, and the third opening 303 is reclosed to prevent cold water from flowing in in advance.

[0082] The movable plate 31 continues to move downward, and when it reaches the third position, the first pressing block 33 contacts the second pressing block 34. At this time, the first opening 301 is still closed by the second pressing block 34, and the third opening 303 is closed by the fourth pressing block 37, ensuring that the cold and hot water are not mixed during the transition stage.

[0083] The power device continues to drive the moving plate 31 downward to the first position. In this process, the first pressing block 33 presses the second pressing block 34 so that the second pressing block 34 is inserted into the fourth opening to open the first opening 301, and the moving plate 31 moves downward to below the first opening 301 to seal the second opening 302.

[0084] Complete the switch: The cold water in the cold water chamber 1 flows into the buffer chamber 3 through the first opening 301, enters the compress bag to realize cold compress, and completes the switch from hot compress to cold compress. In another scheme, in the hot and cold compress device, the cold water chamber 1, the hot water chamber 2 and the buffer chamber 3 are all hollow rectangular parallelepiped, the top and bottom of the buffer chamber 3 are both protruding from the top and bottom of the cold water chamber 1 and the hot water chamber 2, the buffer chamber 3 has a first side wall and a second side wall arranged opposite to each other, the buffer chamber 3 and the cold water chamber 1 share the first side wall, the buffer chamber 3 and the hot water chamber 2 share the second side wall, the first opening 301 and the third opening 303 are both located on the first side wall, the second opening 302 is located on the second side wall, and the third opening 303 is close to the top of the cold water chamber 1, so as to avoid the cold water from entering the buffer chamber 3 from the third opening 303 when it is not needed, and the cold water will flow into the buffer chamber 3 at will because the position of the third opening 303 is too low and the liquid level is slightly high, so as to ensure that the system operates in the set manner and improve the accuracy and controllability of the use of the hot and cold compress device. In another embodiment, in the hot and cold compress device, a base 38 and a top seat 39 are respectively provided at the bottom and the top of the cache chamber 3, and the fourth opening and the fifth opening are respectively located at the outer edges of the base 38 and the top seat 39.

[0085] In another embodiment, in the hot and cold compress device, Figure 1 As shown, when the movable plate 31 is located at the first position, the first pressing block 33 presses the second pressing block 34, and both the first pressing block 33 and the second pressing block 34 are inserted into the fourth opening, and the movable plate 31 fits with the base 38; Figure 2 As shown, when the moving plate 31 is located at the second position, the third pressing block 35 presses the fourth pressing block 37 , and both the third pressing block 35 and the fourth pressing block 37 are inserted into the fifth opening, and the moving plate 31 fits against the top seat 39 .

[0086] The design of the movable plate 31 being fitted with the base 38 or the top seat 39 and the pressure block being inserted into the corresponding opening can provide clear upper and lower limit positions for the movable plate 31, and play a role in precise positioning. The movable plate 31, driven by the power device, can be accurately positioned each time it reaches the first position or the second position, ensuring that the cold and hot compress device delivers cold water or hot water according to the designed logic and path, and ensuring the reliability and repeatability of the device operation.

[0089] In another embodiment, in the hot and cold compress device, a screw rod is arranged on the cache chamber 3 in the vertical direction, and the screw rod is rotatably connected to the top and bottom of the cache chamber 3. The screw rod is connected to a power device and is driven to rotate by the power device. A nut matching it is arranged on the screw rod, and the nut is fixedly connected to the middle part of the movable plate 31.

[0090] The movable plate 31 is driven by a screw rod and a nut in conjunction with a power device. This driving method makes the movement of the movable plate 31 more stable and precise, and can more accurately control the opening and closing of each opening, thereby achieving more precise supply and switching of hot and cold water, and improving the accuracy and reliability of device control.

[0091] In another embodiment, in the hot and cold compress device, the first elastic member 32 and the second elastic member 36 are both springs.

[0092] The first elastic member 32 and the second elastic member 36 are determined to be springs, and the stable elastic characteristics of the springs are used to ensure that each pressure block can be accurately reset during the operation of the device, thereby ensuring the stability and reliability of the device operation and reducing device failures caused by failure of the elastic members.

[0093] Methods for using the hot and cold compress device include: When cold compress is needed, the power device drives the movable plate 31 downward to the first position.

The third pressing block squeezes the fourth pressing block until the third pressing block and the fourth pressing block are both inserted into the fifth opening. The moving plate seals the third opening and fits with the top seat. During this process, hot water continuously flows into the cache chamber through the second opening, completing the switching. When it is necessary to switch from hot compress to cold compress, the power device drives the movable plate downward, the third pressing block and the fourth pressing block gradually withdraw from the fifth opening, the fourth pressing block returns to its original position and seals the third opening, and the movable plate pushes the hot water below it downward; As the movable plate continues to descend, the movable plate continuously pushes the hot water below it downward and flows into the hot water chamber through the second opening. The first pressure block squeezes the second pressure block until the first pressure block and the second pressure block are both inserted into the fourth opening. The movable plate seals the second opening and fits with the base. The first opening opens, and cold water flows into the cache chamber through the first opening, completing the switch.
