Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a drug evaporation box and a pillow. Background Technology

[0002] Some existing pillows contain a drug vaporizer that releases medication to aid sleep. However, this vaporizer remains constantly open and cannot be closed, leading to significant medication waste and low utilization. To address this, a solution is to utilize the weight of the user's head and neck when using the pillow to open the vaporizer, making its opening and closing completely linked to pillow use. While the vaporizer can close when the user removes the pillow, the open time is still too long. The pillow lacks a delayed-closing mechanism after use, posing health risks due to excessive medication absorption, wasting medication, shortening its lifespan, increasing the frequency of medication replacement and maintenance, and negatively impacting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drug evaporation box and pillow with a time-delay switch assembly. Inside the drug evaporation box, a switch plate assembly driven by a pneumatic time-delay switch is installed. The pneumatic time-delay switch inflates and triggers the switch plate assembly under external downward pressure. While the downward pressure is present, the switch plate assembly closes by slowly deflating, ensuring that the closing of the switch plate assembly is independent of the downward pressure. This effectively shortens the opening time of the switch plate assembly, meeting usage requirements, reducing drug evaporation, extending drug lifespan, decreasing the frequency of drug replacement and maintenance, and improving ease of use.

[0004] This invention is achieved through the following method: a drug evaporation box with a time-delay switch assembly, comprising a housing with a receiving groove on its top surface, a pressure plate disposed on the top surface of the housing, and a time-delay switch assembly disposed within the housing. The time-delay switch assembly includes a pneumatic time-delay switch and a switch plate assembly driven by the pneumatic time-delay switch. The pressure plate, triggered by force, drives the switch plate assembly to the open state via the pneumatic time-delay switch, so that the pneumatic time-delay switch can drive the switch plate assembly to the closed state after a preset time. By providing a switch plate assembly driven by the pneumatic time-delay switch within the drug evaporation box, the pneumatic time-delay switch can inflate and trigger the switch plate assembly when the pressure plate receives external downward pressure and moves downward. When the downward pressure exists, it slowly deflates to drive the switch plate assembly to close. This ensures that the opening of the switch plate assembly is correlated with the action of the pressure plate, while the closing of the switch plate assembly is independent of the action of the pressure plate. This effectively shortens the opening time of the switch plate assembly, meeting usage requirements, reducing drug evaporation, extending drug lifespan, reducing the frequency of drug replacement and maintenance, and improving ease of use.

[0005] Preferably, the pneumatic delay switch includes a compressed air chamber and a pneumatic component. The pneumatic component includes a movable part connected to the switch assembly and a built-in deformable air chamber with a delayed vent. The compressed air chamber is compressed and deformed by a pressure plate, forming high-pressure gas input into the deformable air chamber. The deformable air chamber expands and, through the movable part, drives the switch assembly to the open state. The high-pressure gas in the deformable air chamber is discharged and contracts through the delayed vent, causing the movable part to reset and drive the switch assembly to the closed state. The compressed air chamber can generate high-pressure gas that is supplied to the deformable air chamber within the pneumatic component when the pressure plate is pressed down. The expanded deformable air chamber drives the switch assembly to the open state through the movable part. The deformable air chamber can exhaust gas and contract through the delayed vent, causing the switch assembly to switch to the closed state. The deformable air chamber can exhaust gas independently, and the compressed air chamber can be filled with gas independently, so that the switch assembly can independently perform a closing action without the compressed air chamber resetting.

[0006] Preferably, the pneumatic component is tubular, including a sleeve and a movable tube inserted within the sleeve. The movable tube is telescopically inserted into the sleeve and encloses the deformable air chamber. A spring is provided between the inner port of the movable tube inserted into the sleeve and the outer port of the sleeve into which the movable tube is inserted. The deformable air chamber is inflated and elongated, compressing the spring. The spring has a preload force that drives the deformable air chamber to contract and exhaust air through a delayed exhaust port. The spring, through a resetting movable part, drives the switch plate assembly to switch to the closed state. The movable tube is axially telescopically inserted into the sleeve and encloses the axially deformable deformable air chamber. The spring is compressed by the sleeve and the movable tube and accumulates a preload force that drives the deformable air chamber to contract, so that the deformable air chamber slowly releases air under the drive of the spring and drives the switch plate assembly to switch to the closed state through the movable part, achieving the purpose of delayed closing of the switch plate assembly.

[0007] Preferably, the inner port of the movable tube is provided with an outwardly extending internal limiting ring, and the outer port of the sleeve is provided with an inwardly extending external limiting ring. The spring is disposed between the sleeve and the movable tube and is held and positioned by the external and internal limiting rings. The internal limiting ring can slide along the inner wall of the sleeve, and the outer wall of the movable tube can slide along the inner edge of the external limiting ring. This improves the sealing reliability, prevents high-pressure gas in the deformation chamber from leaking out through the gap between the movable tube and the sleeve, and also guides the movable tube, ensuring that it can move axially and telescopically along the sleeve. In addition, the spring is sleeved on the movable tube and held and limited by the internal and external limiting rings, ensuring that the preload generated by the spring compression can drive the movable tube to insert into the sleeve and contract the deformation chamber.

[0008] Preferably, the outer end of the movable tube is exposed outside the sleeve and forms the movable part. The movable part is always exposed outside the sleeve, which facilitates connection with the switch plate assembly via the connecting rod.

[0009] Preferably, the pressure plate has several evenly distributed through holes, so that the drug-carrying gas in the containment tank can diffuse upward through the through holes after passing through the switch plate assembly in the open state, effectively reducing the obstruction of the pressure plate to the diffusion of the drug-carrying gas.

[0010] Preferably, the receiving tank is equipped with a drug module, and the drug-laden gas generated by the drug module diffuses outward after passing through the switch panel assembly which is in the open state. The drug module is installed at the bottom of the receiving tank for convenient sealed storage and to prevent the drug-laden gas from leaking out.

[0011] Preferably, the switch plate assembly includes an evaporating plate embedded and fixed at the opening of the receiving groove, and a movable plate that can move horizontally along the top surface of the evaporating plate. The evaporating plate has a vertically penetrating evaporating hole, and the movable plate has a vertically penetrating movable hole. The movable plate moves horizontally back and forth, allowing the switch plate assembly to switch between an open state where the evaporating hole and the movable hole are vertically aligned and connected, and a closed state where the evaporating hole and the movable hole are vertically misaligned and blocked. The evaporating plate is fixed to the housing, and the movable plate can move horizontally back and forth along the top surface of the evaporating plate, allowing the switch plate assembly to switch back and forth between the open and closed states, which facilitates control and improves the reliability of opening and closing. The evaporating hole and the movable hole are evenly distributed on the evaporating plate and the movable plate, respectively. This reduces the translational distance of the movable plate by reducing the size of the evaporating hole and the movable hole, thus facilitating precise control. Furthermore, increasing the number of evaporating holes and movable holes improves the diffusion efficiency of the drug-carrying gas.

[0012] Preferably, the movable part is provided with a vertically arranged connecting rod. The bottom end of the connecting rod is fixedly connected to the movable part, and the top end passes through the evaporation plate and is fixedly connected to the movable plate. The connecting rod drives the movable plate to reciprocate relative to the evaporation plate, thereby switching the switch plate assembly between the open and closed states. The connecting rod bridges between the movable part and the movable plate, serving to transmit horizontal forces and ensuring that the movable plate and the movable part are linked and control the opening and closing of the switch plate assembly. The evaporation plate has a long, narrow hole for the connecting rod to pass through vertically, ensuring that the connecting rod can move horizontally with the movable part.

[0013] Preferably, the pressure plate has a compression column on its bottom surface, and the compressed air chamber is a tubular structure with an exposed top. The compression column is vertically insertable into the compressed air chamber and its gaps are sealed by a sealing ring. When the pressure plate descends under pressure, the compression column pushes the air in the compressed air chamber, forming high-pressure gas that is then supplied to the deformation air chamber. The compression column is fixedly connected to and linked with the pressure plate. The compression column can be inserted into the compressed air chamber when the pressure plate descends under pressure, allowing the air in the compressed air chamber to be compressed into high-pressure gas and input into the deformation air chamber. A sealing ring is provided between the outer wall of the compression column and the inner wall of the cylindrical compressed air chamber to prevent air leakage.

[0014] Preferably, the bottom wall of the compressed air chamber is provided with a one-way air supply valve that communicates with the outside. The extrusion column is reset upward and draws in outside air through the one-way air supply valve. The one-way air supply valve only allows outside air to enter the compressed air chamber, ensuring that the compressed air chamber can be replenished with air when the extrusion column moves upward, and preventing the high-pressure gas in the compressed air chamber from being discharged into the outside space.

[0015] Preferably, the bottom of the compressed air chamber is connected to the deformation air chamber through a one-way valve. The high-pressure gas generated in the compressed air chamber passes through the one-way valve and is delivered to the deformation air chamber. The one-way valve only allows the high-pressure gas in the compressed air chamber to be delivered to the deformation air chamber, preventing the high-pressure gas in the deformation air chamber from flowing back to the compressed air chamber.

[0016] Preferably, the extrusion column passes vertically through the switch plate assembly and is inserted into the compressed air chamber. After passing through the corresponding holes on the movable plate and the evaporation plate, the extrusion column is inserted into the compressed air chamber located on the bottom wall of the receiving tank. The holes on the movable plate are elongated to meet the requirements for horizontal movement of the movable plate.

[0017] Preferably, an annular elastic ring is provided between the periphery of the pressure plate and the periphery of the evaporation plate. The elastic ring is deformed by the pressure plate and accumulates a preload force that drives the pressure plate to return to its original position. The elastic ring can drive the pressure plate to return to its original position and prepare for the re-formation of high-pressure gas.

[0018] Preferably, the housing includes a base and a cover ring that covers the base. The cover ring has a receiving groove in its center. The periphery of the top surface of the base and the periphery of the bottom surface of the cover ring are vertically stacked and clamp the periphery of the evaporation plate. A limiting ring is provided on the inner edge of the top surface of the cover ring, and a limiting edge is provided on the periphery of the pressure plate. The bottom surface of the limiting ring abuts against the top surface of the limiting edge and prevents the pressure plate from detaching from the housing. The limiting ring vertically limits the limiting edge, preventing the pressure plate from detaching from the housing.

[0019] A pillow includes a pillow body with a mounting groove in the center of its bottom surface. A drug vaporization box is disposed within the mounting groove, and a through-hole diffusion channel is provided between the top wall of the mounting groove and the top surface of the pillow body. The mounting groove serves to conceal and protect the drug vaporization box, and the drug-containing gas generated by the box diffuses outward through the diffusion channel.

[0020] The beneficial effects of this utility model are as follows: A switch plate assembly driven by a pneumatic delay switch is set inside the drug evaporation box. The pneumatic delay switch can be inflated and trigger the switch plate assembly when the pressure plate receives external downward pressure and moves downward. When the downward pressure exists, the switch plate assembly is closed by slowly releasing air. This makes the opening of the switch plate assembly and the action of the pressure plate interconnected, while the closing of the switch plate assembly and the action of the pressure plate are independent of each other. This not only effectively shortens the opening time of the switch plate assembly to meet the usage requirements, but also reduces drug evaporation, extends the drug's service life, reduces the frequency of drug replacement and maintenance, and improves the convenience of use.

[0028] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] This embodiment provides a drug evaporation box.

[0031] like Figure 1The illustrated drug evaporation box includes a housing with a receiving groove on its top surface, a pressure plate 2 disposed on the top surface of the housing, and a time-delay switch assembly disposed within the housing. The time-delay switch assembly includes a pneumatic time-delay switch 3 and a switch plate assembly driven by the pneumatic time-delay switch 3. The pressure plate 2, triggered by force, drives the switch plate assembly to the open state via the pneumatic time-delay switch 3, allowing the pneumatic time-delay switch 3 to reset the switch plate assembly to the closed state after a preset time. The switch plate assembly, driven by the pneumatic time-delay switch, is disposed within the drug evaporation box. The pneumatic time-delay switch inflates and triggers the switch plate assembly when the pressure plate 2 receives external downward pressure and moves downward. While the downward pressure exists, it slowly deflates, driving the switch plate assembly to close. This ensures that the opening of the switch plate assembly is correlated with the action of the pressure plate 2, while the closing of the switch plate assembly is independent of the action of the pressure plate 2. This effectively shortens the opening time of the switch plate assembly, meeting usage requirements, reducing drug evaporation, extending drug lifespan, reducing the frequency of drug replacement and maintenance, and improving ease of use.

[0032] In this embodiment, the switch plate assembly includes an evaporating plate 13 embedded and fixed at the opening of the receiving groove, and a movable plate 14 that can move horizontally along the top surface of the evaporating plate 13. The evaporating plate 13 has a vertically penetrating evaporation hole 16, and the movable plate 14 has a vertically penetrating movable hole 15. The movable plate 14 moves horizontally back and forth, so that the switch plate assembly can switch between an open state where the evaporating hole 16 and the movable hole 15 are vertically aligned and connected, and a closed state where the evaporating hole 16 and the movable hole 15 are vertically misaligned and blocked. The movable hole 15 on the movable plate 14 corresponds one-to-one with the evaporating hole 16 on the evaporating plate 13 and has the same cross-sectional profile. The bottom surface of the movable plate 14 is tightly fitted with the top surface of the evaporating plate 13, and the movable plate 14 can move back and forth along the top surface of the evaporating plate 13, so that the switch plate assembly can switch back and forth between the open and closed states.

[0033] When the switch plate assembly is in the open state, the movable hole 15 on the movable plate 14 and the evaporation hole 16 on the evaporation plate 13 are aligned one by one. The drug-laden gas located below the switch plate assembly can diffuse upward through the aligned evaporation hole 16 and movable hole 15, and then be transported outward through the through hole 12 provided on the pressure plate 2.

[0034] When the switch plate assembly is in the closed state, the movable hole 15 on the movable plate 14 is blocked by the solid wall between the adjacent evaporation holes 16 on the evaporation plate 13, and the evaporation holes 16 on the evaporation plate 13 are blocked by the solid wall between the adjacent movable holes 15 on the movable plate 14. The top surface of the evaporation plate 13 and the bottom surface of the movable plate 14 are tightly fitted to ensure that the drug-containing gas at the evaporation hole 16 cannot diffuse outward through the misaligned movable hole 15.

[0035] In this embodiment, the outer end of the movable tube 8 is exposed outside the sleeve 7 and forms the movable part 5. The movable part 5 is provided with a vertically arranged connecting rod 17. The bottom end of the connecting rod 17 is fixedly connected to the movable part 5, and the top end passes through the evaporation plate 13 and is fixedly connected to the movable plate 14. The connecting rod 17 drives the movable plate 14 to reciprocate relative to the evaporation plate 13, so that the switch plate assembly switches between the open and closed states. The connecting rod 17 is arranged vertically, with its top end fixedly connected to the movable plate 14 and its bottom end fixedly connected to the movable part 5 on the pneumatic component, so that the movable plate 14 and the movable part 5 are linked, thereby ensuring that the movable plate 14 can be controlled by the pneumatic delay switch 3 to realize the switching of the switch plate assembly between the open and closed states.

[0036] In this embodiment, the pneumatic delay switch 3 includes a compressed air chamber 4 and a pneumatic component with a deformable air chamber (such as...). Figure 2 As shown, the pneumatic component includes a movable part 5 connected to the switch plate assembly and a built-in deformation chamber with a delayed vent 6. The compression chamber 4 is compressed and deformed by the pressure plate 2, forming high-pressure gas input into the deformation chamber. The deformation chamber expands and inflates, driving the switch plate assembly to the open state through the movable part 5. The high-pressure gas in the deformation chamber is discharged through the delayed vent 6 and contracts, causing the movable part 5 to reset and driving the switch plate assembly to the closed state. The compression chamber 4 is equipped with a one-way valve 20 for replenishing gas, and the deformation chamber is provided with a delayed vent 6. When the pressure plate 2 is subjected to a downward force, the compression chamber 4 can form high-pressure gas through the compression space. The deformation chamber receives the high-pressure gas and deforms by elongation, causing the movable part 5 to move from the first position close to the sleeve 7 to the second position away from the sleeve 7, thereby driving the switch plate assembly to the open state and ensuring that the drug-carrying gas can be discharged smoothly.

[0037] During this process, spring 9 is compressed and accumulates pre-tightening force to drive movable part 5 back to the first position. The deformation gas chamber stores high-pressure gas higher than the external air pressure. This high-pressure gas in the deformation gas chamber is slowly discharged through the delayed vent 6. When the air pressure in the deformation gas chamber decreases, movable tube 8 moves to the first position under the drive of spring 9, thereby driving the switch plate assembly to switch to the closed state via movable part 5. In the above process, the switch plate assembly can switch to the open state when the pressure plate 2 is subjected to vertical compression, and diffuse the drug-carrying gas outwards. After the high-pressure gas in the deformation gas chamber is discharged, the switch plate assembly is controlled to switch to the closed state and stop dispersing the drug-carrying gas. The action of the switch plate assembly switching to the open state is related to the action of the pressure plate 2 descending under pressure; the action of the switch plate assembly switching to the closed state is related to the action of the high-pressure gas in the deformation gas chamber being discharged, but not to whether the pressure plate 2 rises and resets, thus achieving a delayed automatic closing of the drug vaporization box.

[0038] In this embodiment, the pneumatic component is tubular, including a sleeve 7 and a movable tube 8 inserted within the sleeve 7. The movable tube 8 is telescopically inserted into the sleeve 7 and encloses the deformation air cavity. A spring 9 is provided between the inner port of the movable tube 8 inserted into the sleeve 7 and the outer port of the sleeve 7 where the movable tube 8 is inserted. The deformation air cavity is inflated and elongated, compressing the spring 9. The spring 9 has a preload force that drives the deformation air cavity to contract and exhaust air through a delayed exhaust port. The spring 9 drives the switch plate assembly to switch to the closed state through the reset movable part 5. The movable tube 8 and the sleeve 7 are interlocked, which can not only enclose the variable volume deformation air cavity, but also guide the movable tube 8 to reciprocate along the axis of the sleeve 7, preventing jamming.

[0039] In this embodiment, the inner port of the movable tube 8 is provided with an outwardly extending internal limiting ring 10, and the outer port of the sleeve 7 is provided with an inwardly extending external limiting ring 11. The spring 9 is disposed between the sleeve 7 and the movable tube 8 and is clamped and positioned by the external limiting ring 11 and the internal limiting ring 10. The spring 9 is sleeved on the outer wall of the movable tube 8, and the two ends of the spring 9 abut against the external limiting ring 11 and the internal limiting ring 10, respectively. When the deformation gas chamber is inflated and expanded, the movable part 5 moves to the second position, and the internal limiting ring 10 moves closer to the external limiting ring 11 and compresses the spring 9, so that the spring 9 accumulates a preload force to drive the movable part 5 to reset to the first position, so that the movable tube 8 can retract into the sleeve 7 under the drive of the spring 9 after the high-pressure gas in the deformation gas chamber is discharged.

[0040] In this embodiment, a drug module 23 is provided in the receiving tank. The drug-laden gas generated by the drug module 23 diffuses outward after passing through the switch plate assembly which is in the open state. A plurality of evenly distributed through holes 12 are formed on the pressure plate 2, allowing the drug-laden gas in each area below the pressure plate 2 to diffuse outward through the corresponding through holes 12. When the switch plate assembly is switched to the open state, the drug-laden gas diffuses upward through the through holes 12 after passing through the switch plate assembly.

[0041] In this embodiment, the bottom surface of the pressure plate 2 is provided with a squeezing column 18, and the compressed air chamber 4 is a tubular structure with its top exposed. The squeezing column 18 can be inserted into the compressed air chamber 4 in a vertically movable manner and the gap is sealed by a sealing ring 19. When the pressure plate 2 is lowered by force, the squeezing column 18 pushes the air in the compressed air chamber 4 and forms high-pressure gas that is delivered to the deformation chamber. The bottom side wall of the squeezing column 18 is provided with an annular groove for the inner edge of the sealing ring 19 to be embedded. The sealing ring 19 is fitted into the annular groove, which not only effectively improves the sealing performance and prevents high-pressure gas from leaking out through the gap between the squeezing column 18 and the side wall of the compressed air chamber 4, but also plays a positioning role for the sealing ring 19.

[0042] In this embodiment, the bottom wall of the compressed air chamber 4 is provided with a one-way valve 20 for air replenishment that communicates with the outside. The extrusion column 18 is reset upwards and draws in outside air through the one-way valve 20. The one-way valve 20 can prevent the high-pressure gas in the compressed air chamber 4 from leaking into the outside space, and can also replenish the compressed air chamber 4 with gas, ensuring that the extrusion column 18 can be raised upwards within the compressed air chamber 4 and providing a sufficient air source for subsequent compression operations. The compressed air chamber 4 is multiple and distributed, which can effectively balance the force state of each area of ​​the pressure plate 2, ensuring that the pressure plate 2 rises and falls in a horizontal posture. It can also increase the volume of the compressed air chamber 4 by increasing the vertical projection area of ​​the compressed air chamber 4, thereby increasing the output of high-pressure gas. At the same time, it can effectively reduce the rising and falling amplitude of the extrusion column 18, thereby reducing the height of the shell and facilitating use.

[0043] In this embodiment, the bottom of the compressed air chamber 4 is connected to the deformation air chamber via a one-way valve 21. The high-pressure gas generated in the compressed air chamber 4 passes through the one-way valve 21 and is delivered to the deformation air chamber. The one-way valve 21 prevents the high-pressure gas in the deformation air chamber from flowing back into the compressed air chamber 4, ensuring that the high-pressure gas can only be discharged through the delayed vent 6.

[0044] In this embodiment, the extrusion column 18 vertically passes through the switch plate assembly and is inserted into the compressed air chamber 4. After passing through the corresponding holes on the movable plate 14 and the evaporation plate 13, the extrusion column 18 is inserted into the compressed air chamber 4 located on the bottom wall of the receiving tank. The holes on the movable plate 14 are elongated to meet the requirements for horizontal movement of the movable plate 14.

[0045] In this embodiment, an annular elastic ring 22 is provided between the periphery of the pressure plate 2 and the periphery of the evaporation plate 13. The elastic ring 22 is deformed by the pressure plate 2 and accumulates a preload force that drives the pressure plate 2 to return to its original position. The elastic ring 22 is annular and arranged along the periphery of the pressure plate 2 to ensure that each area around the periphery of the pressure plate 2 is evenly stressed and maintains a horizontal posture. Preferably, the elastic ring 22 is a helical spring or a compressible sponge strip arranged along the top surface of the limiting edge 29 and the edge of the limiting ring 28, etc., and both should be considered as specific implementations of this embodiment.

[0046] In this embodiment, the housing includes a base 1 and a cover ring 27 that covers the base 1 (e.g., ...). Figure 3 As shown), the cover ring 27 has a receiving groove in the middle. The periphery of the top surface of the base 1 and the periphery of the bottom surface of the cover ring 27 are vertically stacked and clamp and fix the periphery of the evaporation plate 13. The inner edge of the top surface of the cover ring 27 is provided with a limiting ring 28, and the periphery of the pressure plate 2 is provided with a limiting edge 29 (as shown). Figure 4As shown, the bottom surface of the limiting ring 28 abuts against the top surface of the limiting edge 29 and restricts the pressure plate 2 from detaching from the housing. The limiting edge 29 is clamped between the top surface of the elastic ring 22 and the bottom surface of the limiting ring 28, and can obtain movement space by squeezing the elastic ring 22 when the pressure plate 2 is subjected to downward pressure. It can effectively sense the downward pressure and will not detach from the housing.

[0047] In this embodiment, the delayed vent 6 is a sealing component with a small ventilation channel. It can not only block the opening, but also realize the function of exhaust and depressurization through the small ventilation channel, so that the air pressure in the deformation chamber can slowly decrease, thereby causing the movable part 5 to slowly move and realize the function of delayed closing.

[0048] Example 2:

[0049] Compared to Embodiment 1, this embodiment provides a

[0050] like Figure 5 The pillow shown includes a pillow body 24. A mounting groove 25 is provided in the center of the bottom surface of the pillow body 24. The drug vaporization box is housed within the mounting groove 25. A through-hole diffusion channel 26 is provided between the top wall of the mounting groove 25 and the top surface of the pillow body 24. The drug vaporization box is embedded in the mounting groove 25, serving to conceal and protect it. The drug-containing gas generated by the drug vaporization box diffuses into the space above the pillow body 24 through the diffusion channel 26 for absorption by the user.

[0051] In this embodiment, the mounting groove 25 is located in the middle of the bottom surface of the pillow body 24. The depth of the mounting groove 25 matches the height of the drug vaporization box, so that the top surface of the pressure plate 2 fits against the top wall of the mounting groove 25. This not only receives the downward pressure force when the user's head and neck squeeze the pillow and drives the switch assembly to the open state, but also diffuses the drug-carrying gas from the through hole 12 into the space above the pillow body 24 through the diffusion channel 26, ensuring that the user can effectively absorb the drug-carrying gas through breathing.

[0052] In this embodiment, the lower port of the dispersing channel 26 is opened on the top wall of the mounting groove 25 and aligned with the through hole 12 on the pressure plate 2. The upper port of the dispersing channel 26 is opened on both sides of the top surface of the pillow body 24 (e.g., Figure 6 As shown in the figure, it effectively prevents the dissemination channel 26 from being blocked by the user's head and neck, and improves the diffusion efficiency of the drug-carrying gas.

[0053] The other structures and effects of the drug evaporation box described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
