Slow-release multi-purpose medicinal scented pillow

Abstract

This invention relates to a household product, specifically a slow-release, multi-purpose herbal scented pillow, comprising a pillowcase and filling. Its key feature is a compressible and expandable bladder made of non-breathable elastic fabric inside the pillowcase. The bladder has a filling opening and an air tube connected to it, with a switch on the air tube. Beneficial effects: Various fragrances or traditional Chinese herbs can be placed inside the bladder. Normally, the switch is closed, preventing the release of herbal aromas. Opening the switch, especially when the pillowcase is under pressure, compresses the bladder, releasing a large amount of herbal aroma for respiration. When the pressure is released, the bladder expands, allowing air to enter. This controls the release of active ingredients, enhancing the health benefits and extending the pillow's shelf life. Its shelf life is more than four times longer than ordinary herbal pillows. It has excellent regulating and health-promoting effects on various sub-health conditions such as insomnia, cervical discomfort, rhinitis, and cardiovascular blockage. Furthermore, its simple structure, low cost, and ease of use make it a promising essential item for beds.

Description

Technical Field

[0001] This invention relates to a household product, namely a slow-release multi-purpose medicinal scented pillow. Background Technology

[0002] Pillows are common household items, mostly consisting of a pillowcase and filling. In recent years, medicinal pillows have appeared on the market, filled with fragrant Chinese herbs. The aroma and active ingredients of these herbs diffuse through the pillowcase, effectively improving indoor air quality and enhancing health. However, these medicinal pillows share a common drawback: their effectiveness is short-lived. The fragrance and herbs inside the pillow dissipate quickly, fading or disappearing, ending their health benefits. To address this, people add a plastic bag to the pillow, removing it before sleeping. While this extends the effect slightly, the overall effect is minimal. Some of the material's aroma remains in the plastic bag, quickly dissipating upon opening. Without the plastic bag's seal, most of the pillowcase releases the active ingredients for an extended period, not only diminishing the effective period but also spreading throughout the room. Very few of these active ingredients are actually absorbed by the body, preventing the full medicinal effect from being achieved. Furthermore, the herbal ingredients in these pillows are mostly disposable and mixed with other fillings, meaning they cannot be frequently replaced. This results in a short shelf life, limited functionality, and an inability to meet diverse needs. Frequent pillow replacements are often necessary, leading to high costs and waste. While modern high-tech methods could solve these problems, these products are expensive, have a limited target audience, and are difficult to widely adopt. Summary of the Invention

[0003] The purpose of this invention is to provide a slow-release multi-purpose herbal pillow that can be filled with various Chinese herbal medicines as needed, can control the release of odors, has a long shelf life, a wide range of applications, makes full use of effective ingredients, has outstanding health benefits, and is simple in structure, low in cost, and easy to use.

[0004] The above objective is achieved by the following technical solution: Developing a slow-release multi-purpose medicinal aroma pillow, including a pillowcase and an inner filling material, characterized in that: the pillowcase contains a compressible and retractable sac made of non-breathable elastic fabric, the sac has an opening that can be opened and closed, filled with and replaced medicinal materials, the sac is connected to an air tube, and the air tube has a switch. When the switch is opened, the sac can output the medicinal aroma. When the sac is compressed, a large amount of medicinal aroma is output. When the sac is retracted, air is introduced into the sac.

[0005] The outer end of the trachea is equipped with a ventilation mask that can be attached to room items or a person's face.

[0006] The outer end of the trachea is connected to a storage balloon made of an elastic membrane. The storage balloon is equipped with a slow-release valve. The slow-release valve is surrounded by a sleeve. Inside the sleeve is a damping core filled with tiny gaps. The outer end of the damping core is equipped with a microporous membrane.

[0007] The balloon is equipped with a support spring.

[0008] The upper part of the balloon is equipped with a pressure plate, and the lower part is equipped with a bottom plate. Both the pressure plate and the bottom plate are made of rigid plates. A vertical rack is installed under the pressure plate, and a gear that can mesh with the rack is installed on the bottom plate through a bracket. A stirring line extending in all directions is installed on the gear shaft. When the balloon is compressed or popped open, the rack drives the gear and the stirring line to rotate.

[0009] A shearing blade is mounted above the bottom plate of the balloon, and the shearing blade is parallel to and close to the stirring line.

[0010] The balloon is equipped with an inlet valve and an outlet valve, both of which are one-way valves. The outlet valve is connected to an air tube. During balloon compression, the inlet valve is closed and the outlet valve is open. During balloon expansion, the outlet valve is closed and the inlet valve is open.

[0011] Both the air inlet valve and the air outlet valve are provided with an air inlet and an air outlet. A swingable valve plate is installed inside the air inlet. When the valve plate is flat, the air inlet is closed, and when the valve plate is bent, the air inlet is opened.

[0012] The air inlet valve or air outlet valve is a ball valve. One end of the ball valve sleeve is the air inlet, and the other end is the air outlet. There is a sealing ball inside the air inlet, and a spring is abutted behind the sealing ball. The other end of the spring abuts against a protrusion on the inner wall of the sleeve.

[0013] The exhaust valve is equipped with a hysteresis device that delays closure.

[0014] The hysteresis device is equipped with a self-locking spring on the valve plate of the air outlet valve. After the valve plate is opened, the center line of the self-locking spring swings past the valve plate shaft to restrict the return of the valve plate.

[0015] The hysteresis device has a magnet installed on the open side of the valve plate of the air outlet valve. The valve plate is magnetic, and after the valve plate is opened, the magnet attracts the valve plate and restricts the return of the valve plate.

[0016] The hysteresis device is located inside the air outlet valve of the ball valve. That is, a check tooth is provided on the inner wall of the sleeve on which the sealing ball slides. The check tooth is a rough surface composed of multiple convex ridges. After the ball valve is opened, the sealing ball slides into the rough surface and is restricted from returning to its original position.

[0017] The balloon shown has a pressure plate at the upper part and a bottom plate at the lower part. Both the pressure plate and the bottom plate are made of rigid materials. A vertical rack is installed under the pressure plate, and a gear that meshes with the rack is mounted on the bottom plate via a bracket. A stirring line extending in all directions is mounted on the gear shaft. When the balloon is compressed or expanded, the rack drives the gear and the stirring line to rotate. A shearing plate is installed above the bottom plate of the balloon. The shearing plate is parallel to and close to the stirring line. The balloon has an inlet valve and an outlet valve. Both the inlet valve and the outlet valve are one-way valves. The outlet valve is connected to an air tube. During the compression of the balloon, the inlet valve is closed and the outlet valve is open. During the expansion of the balloon, the outlet valve is closed and the inlet valve is open.

[0018] The upper part of the balloon is equipped with a pressure plate, and the lower part is equipped with a bottom plate. Both the pressure plate and the bottom plate are made of rigid materials. The pressure plate is tightly connected to the inner wall of the pillowcase. A support spring is installed inside the balloon. The upper end of the support spring abuts against the pressure plate, and the lower end presses against the bottom surface of the pillowcase. The balloon is equipped with an inlet valve and an outlet valve, both of which are one-way valves. A downward-extending plunger is located in the middle of the pressure plate. The plunger slides in cooperation with a sliding sleeve. A side inlet is opened on one side of the upper middle part of the sliding sleeve, and the lower part of the sliding sleeve... It has a side outlet. The lower end of the sliding sleeve is connected to the base, and the lower end of the base is connected to the bottom plate. The outer periphery of the sliding sleeve is provided with an elastic conical mesh, and the outer periphery of the elastic conical mesh is connected to the inner wall of the balloon. The cone point of the elastic conical mesh is connected to the surface between the side inlet and the side outlet of the sliding sleeve. In the natural state of the balloon, the lower end of the plunger is higher than the side inlet of the sliding sleeve. When the balloon is compressed, the plunger descends to the lower stop point and contacts the base. A filling port is provided on the balloon above the elastic conical mesh, and the filling port is provided with a sealing cap.

[0019] The balloon is equipped with a pressure plate, which is tightly connected to the inner wall of the pillowcase. The pressure plate is a rigid board, and the space above the pressure plate is filled with breathable filler. Support springs are provided on both sides of the balloon. The upper end of the support spring abuts against the pressure plate, and the lower end presses against the bottom surface of the pillowcase. An adhesive sheet is provided between the pressure plate and the balloon to pull each other.

[0020] The beneficial effects of this invention are as follows: The bulb can hold various spices or traditional Chinese medicines. Normally, with the switch closed, the aroma of the spices and herbs cannot be released. When in use, opening the switch allows the aroma to be released, especially when the pillowcase is under pressure from the head, causing the bulb to compress and releasing a large amount of aroma for the user to breathe. When the head leaves the pillowcase, the bulb pops open, allowing air to enter. This controls the output of the effective components of the spices and herbs, improving utilization and extending the pillow's shelf life. Compared to ordinary medicinal pillows, its shelf life is increased by more than four times. It has excellent adjusting and health-preserving effects on various sub-health conditions such as insomnia, rhinitis, cervical discomfort, and cardiovascular blockage. Furthermore, its simple structure, low cost, and ease of use make it a promising essential item for bedding. Attached Figure Description

Detailed Implementation

[0051] First embodiment: Figure 1This invention introduces a slow-release, multi-purpose herbal scented pillow, comprising a pillowcase and an inner filling. The pillowcase 1 is made of common breathable fabric, and the filling 2 is also made of commonly used breathable materials such as rice husks, buckwheat husks, sponge, and latex. Buckwheat husks are the preferred breathable material. Buckwheat husks are pyramidal in shape, with flexible particles, are non-toxic and odorless, and have good breathability, making them an ideal pillow filling material. Compared with the existing technology described above, the feature of this embodiment is that the pillowcase 1 contains a spherical bladder 3.

[0052] Combination Figure 2 As can be seen, the balloon 3 is a hollow body made of non-breathable elastic fabric, and its shape can be various, such as elliptical, cuboid, saddle-shaped, etc. The elliptical shape shown in the figure has better mechanical properties. The balloon can be compressed when subjected to external force, and can spring open and return to its natural state after the external force is released.

[0053] As shown in the figure, the balloon has an openable and closable filling port 4. There are various types of filling ports; the example shown is a tubular opening that fits tightly with the cap. Opening the filling port allows for the filling of the balloon with medicinal materials 10. These medicinal materials include spices, traditional Chinese medicine, and other odor-producing ingredients. After filling, the cap is tightened to close the filling port. Once closed, the filling port must be airtight. For elastic materials, the opening can be removed after filling. The disappearance of this opening should be considered equivalent to the closure of the filling port.

[0054] As shown in the diagram, an air tube 6 is connected to the air outlet 5 of the balloon. The air tube can be made of flexible rubber tubing, and one end can be placed in an appropriate position as needed to deliver the aroma emitted by the medicinal herbs to the desired location. For ease of use, a diffuser hood 9 can also be attached to the outer end of the air tube. The diffuser hood can be placed in a corner of the room, preferably near the bedside.

[0055] A switch 8 is located on the trachea 6. The switch shown is a manual switch; when needed, it is turned on, allowing gas from the balloon to be released and exchanged with outside air. When a person is resting in bed with their head pressed against the pillowcase, the balloon is compressed, causing a sudden increase in internal pressure, which releases a large amount of medicinal gas through the trachea. When the external force is released, i.e., when the person's head leaves the pillowcase, the balloon automatically expands due to its own elasticity, causing a sharp drop in internal pressure, creating negative pressure, and drawing in ambient air. After use, the switch can be turned off, and gas from the balloon will no longer be released.

[0056] A filter screen 7 should be installed inside the air outlet of the balloon. During exhalation, the filter screen prevents fine particles of spices and herbs from entering the trachea. During inhalation, the filter screen blocks impurities from the ambient air. Of course, if the environment is relatively clean, or if the filling material inside the balloon is made of larger particles, this filter screen may not be necessary.

[0057] Instructions for use: First, fill the balloon with spices or traditional Chinese medicine, especially those that easily release fragrance. Normally, because the balloon is closed, the fragrance of the herbs cannot escape. When resting, turn on the switch, lie down on the bed with your head pressed against the pillow. The balloon is compressed, and the medicinal aroma rushes into the trachea and is released from the outside of the trachea, ready for inhalation. When you finish resting and lift your head off the pillow, the balloon quickly expands, returning to its natural state. The space inside the balloon suddenly increases, and the air pressure suddenly decreases. Air enters the balloon and mixes with the herbs, generating new gas. At this point, turn off the switch; the balloon returns to a sealed state, and the gas inside no longer exits, storing energy for the next output. Two specific usage methods are described below:

[0058] Figure 3 This article introduces one method of using the sustained-release multi-purpose herbal scented pillow: hang the gas diffuser 9 at the head of the bed. When a person is resting in bed, the switch can be turned on, and the gas in the balloon can rush out of the gas diffuser for the person to breathe.

[0059] Figure 4 Another method of using the slow-release multi-purpose herbal scented pillow is introduced: tie the air diffuser 9 around the person's mouth and nose. This allows for greater absorption and utilization of the herbal aroma. Furthermore, this method has another important function: when the head presses against the pillow to the set height, the head pressure and the supporting force of the airbag balance, the airbag stops compressing, and the pressure inside the airbag tends to balance with the external air pressure, thus ceasing gas exchange. At this time, because the air diffuser is close to the person's mouth and nose, the person can still breathe to reduce the air pressure in the trachea, thereby continuously inhaling the aroma emitted by the herbal medicine from the airbag. Even after the airbag compression process stops, the person can continue to breathe in the herbal aroma.

[0060] Figure 4 It is evident that the added mechanisms have increased the height of pillows, exceeding the height required by humans. Therefore, pillows are not placed on top of mattresses or quilts, but rather outside of them. From this, we can infer that with changes in pillow function and mechanism, the space at the head of the bed can be utilized to add more functions to the bedside area.

[0061] Experiments have shown that the fragrance emitted by the air bladder can significantly improve indoor air quality and promote human health. For example, lavender, magnolia, jasmine, schisandra, jujube seed, agarwood, and benzoin, ground into granules and filled into the air bladder, will emit a special, refreshing aroma that significantly improves symptoms such as insomnia, qi deficiency, chest tightness, and neck pain. Granules made from crushed Xanthium sibiricum, magnolia flower bud, saposhnikovia divaricata, angelica dahurica, and peppermint have a significant relieving effect on respiratory diseases such as rhinitis, sinusitis, and bronchitis. Granules made from crushed salvia miltiorrhiza, chuanxiong rhizome, angelica sinensis, safflower, notoginseng, and borneol have outstanding effects in improving and adjuvantly treating hyperlipidemia, hypertension, and cardiovascular and cerebrovascular diseases.

[0062] Product shelf-life comparison experiment: Ordinary pillows were filled with the same fragrances and traditional Chinese medicines. During the day, the pillows were placed in a plastic bag and used at night. The odor noticeably faded after about a month, and completely disappeared after about two months. However, the pillow in this embodiment retained its odor for more than 10 months and could be replaced for continued use. It is evident that this product solves the problems existing in similar products, achieves its invention objective, and has a very promising application prospect.

[0063] The second embodiment further addresses the issue of delayed deflation after balloon compression stops, building upon the first embodiment. For example... Figure 5 As shown, a gas storage balloon 11 is attached to the outer end of the trachea. This balloon, similar to existing balloons, is made of a highly elastic membrane. When the internal pressure exceeds ambient pressure, the balloon inflates to hold a larger amount of gas. Combined with... Figure 6 As can be seen, a slow-release valve 12 is installed on the outside of the gas storage balloon. Outside the slow-release valve is a sealed sleeve 13, inside which is a damping core 14 filled with tiny pores. The damping core can be made of sintered fine quartz sand powder, containing countless tiny and tortuous pores. A microporous membrane 15 is installed at the outer end of the damping core. The microporous membrane is a commercially available product, with the smallest pore size being approximately 0.001 mm. Because the gas inside the gas storage balloon often contains fragrances or active ingredients from traditional Chinese medicine, which exist mostly in the form of molecular clusters, and whose particle diameter is much larger than that of pure air, the release time from the gas storage balloon is significantly increased due to the adsorption and friction of the damping core and the microporous membrane. During use, the gas expelled from the balloon is stored inside the balloon and then slowly released through the slow-release valve, resulting in a relatively long release time. Even when the airway is closed, the gas storage balloon can continue to release for a period of time. Experiments have shown that the gas storage balloon continues to release odors for about 30 minutes after the balloon compression process stops. After the gas storage balloon stops releasing odors, the released odors will continue to linger in the room for a considerable period. If the user adjusts their lying position every 1-1.5 hours, they can enjoy the aroma of the medicine for most of the resting time, and the benefits to their health are self-evident.

[0064] The third embodiment enhances the elasticity of the balloon based on the aforementioned embodiments. Generally, balloons themselves possess good elasticity; a balloon compressed by external force can quickly spring back to its natural state when the force is removed. However, relying solely on the elasticity of the material itself requires expensive materials, and the elasticity parameters are relatively limited, with little room for adjustment. Therefore, this embodiment provides a new structure: such as... Figure 7 As shown, a support spring 16 is installed inside the balloon 3. The support spring can be screwed into the balloon through the filling port, with its upper end abutting the upper inner part of the balloon and its lower end abutting the lower inner part of the balloon. In this way, the support spring can participate in the contraction and expansion action together with the balloon, which greatly increases the overall elastic range of the balloon, especially significantly improving its return-to-position performance. Moreover, the support spring can be replaced as needed to improve the pillow's performance and broaden its applicability.

[0065] Fourth embodiment: An improvement upon the aforementioned embodiments. For example... Figure 8 , Figure 9 As shown, the upper inner part of the balloon 3 is equipped with a pressure plate 17, and the lower inner part is equipped with a base plate 21. Both the pressure plate and the base plate are rigid plates, and a vertical rack 18 is mounted under the pressure plate. A gear 19 that meshes with the rack is mounted on the base plate via a bracket 20. The bracket shown in the figure has a horizontally placed gear shaft, supported by uprights on both sides, and the lower ends of the uprights are fixed to the base plate. The rack and gear here use a large transmission ratio as much as possible. Taking a transmission ratio of 1:3 as an example, that is, for one stroke of the rack, the gear can rotate 3 revolutions. The gear shaft is equipped with stirring lines 22 extending in all directions. There are two sets of racks, gears and stirring lines shown in the figure, installed opposite each other at both ends of the pressure plate. On both sides of each set of gears, a set of stirring lines is installed on the gear shaft. The stirring lines can be made of thin steel wire or other hard filaments, and one rack can drive two or more sets of stirring lines to work. For ease of installation, the stirring lines in the figure are installed around the stirring wheel. During the compression or expansion of the balloon, the rack moves up and down, driving the gears and stirring line to rotate repeatedly, stirring the medicinal materials inside the balloon and releasing more of their aroma. Later in the product's lifespan, the user can repeatedly press the pillowcase to further activate the rack, gears, and stirring line, ensuring thorough mixing of the medicinal materials and releasing their active ingredients and aroma more completely.

[0066] Fifth embodiment: An improvement upon the fourth embodiment. For example... Figure 10 , Figure 11As shown, the upper inner part of the balloon 3 is provided with a pressure plate 17, and the lower inner part is provided with a base plate 21. Both the pressure plate and the base plate are rigid plates, and a vertical rack 18 is installed under the pressure plate. A gear 19 that can mesh with the rack is mounted on the base plate via a bracket 20, and a stirring line 22 extending in all directions is mounted on the shaft of the gear. The improvement is that a shearing blade 23 is installed above the base plate 21. As can be seen in the figure, the shearing blade can be a rigid narrow strip with sharp edges on the upper and lower sides, installed on both sides of a flat shaft, which is supported by two columns. The columns are installed on the base plate, and the shearing blade is parallel to and close to the stirring line, with a distance of less than 50 mm being preferable.

[0067] During operation, when the balloon contracts or expands, the rack moves vertically up and down, which drives the gears and stirring line to rotate, turning the material up and throwing it down. The material is then cut relative to the shearing blades, further crushing it and allowing the active ingredients to be better released.

[0068] The sixth embodiment: Based on the fourth and fifth embodiments, further improvements are made to the balloon with reference to the third embodiment. For example... Figure 12 , Figure 13 As shown, the balloon 3 is equipped with a pressure plate 17 and a base plate 21, and a support spring 16 is provided between the pressure plate and the base plate. There are two support springs in the figure, which are installed on the left and right sides of the filling port, respectively, which can better enhance the elasticity of the balloon and make its performance more stable and reliable.

[0069] Seventh embodiment: An improvement upon the foregoing embodiments. For example... Figure 14 As shown, the balloon 3 is equipped with two one-way valves: an inlet valve 24 and an outlet valve 25. Various one-way valves can be used; the example shown is a disc-type one-way valve. The disc-type one-way valve has a tube-like casing with an inlet end 26 and an outlet end 27. On the inside of the inlet end, facing the outlet end, is a swingable disc 28. The swingable disc can take many forms. The disc shown is a flexible, flat plate connected to the tube at its upper end. When the disc is flat, it covers the inlet end, closing it. When the disc is bent, the inlet end opens. Figure 15 , Figure 16 As can be seen, the outlet ends of both the inlet and outlet valves point to the right of the diagram. However, for the balloon, the outlet end of the inlet valve is inside the balloon, while the outlet end of the outlet valve is on the outside of the balloon. (Combined...) Figure 15 As can be seen, during balloon compression, the space inside the balloon decreases, the air pressure increases, and the valve plate of the intake valve is pushed towards the intake side, closing the intake end of the intake valve. Conversely, the valve plate of the exhaust valve is pushed open, opening the exhaust end. Combined with... Figure 16As can be seen, during the balloon's deployment, the space inside the balloon increases, the air pressure drops sharply, and the valve plate of the exhaust valve is sucked onto the air inlet end by the negative pressure, closing the exhaust valve. At the same time, the valve plate of the air inlet valve is attracted by the negative pressure and bends inward towards the balloon, opening the air inlet end of the air inlet valve and allowing outside air to enter the balloon.

[0070] Normally, because the valve of the airbag is closed, the aroma of the traditional Chinese medicine cannot be released. When a person rests, lying on the bed with their head pressed against the pillow, the airbag is compressed. That is... Figure 15 As shown, when the air valve opens, the medicinal aroma from the airbag enters the trachea and is released from the outside of the trachea, making it readily available for breathing. When the person finishes resting and their head leaves the pillow, the airbag quickly expands, returning to its natural state. The space inside the airbag suddenly increases, and the air pressure suddenly decreases. The valve of the air inlet valve is immediately sucked open, allowing air to enter the airbag. At the same time, the valve of the air outlet valve is also sucked closed, restoring the airbag to a sealed state, and the gas inside the airbag no longer exits.

[0071] Eighth embodiment: Based on the aforementioned embodiments, the performance of delayed output of beneficial gas after balloon compression is further enhanced. Specifically, the balloon's outlet valve is equipped with a hysteresis valve 30 that closes after a delay.

[0072] Figure 17 , Figure 18 A relatively simple hysteresis device is illustrated, in which a self-locking spring 31 is mounted on the valve plate 28 of the air outlet valve 25. The self-locking spring can be a spring made of coiled metal wire or a rubber band. The upper end of the self-locking spring is connected to the housing of the air outlet valve, and the lower end is connected to the upper middle part of the valve plate. The valve plate is hinged to the inside of the air inlet of the air outlet valve via the valve plate shaft. When the valve plate is closed, the center line of the self-locking spring is on the left side of the valve plate shaft, that is, on the side of the air inlet. When the balloon is compressed, the gas pushes open the valve plate. As the valve plate swings, the center line of the self-locking spring crosses the axis of the valve plate shaft, that is, it exerts a pulling force on the valve plate away from the direction of the air inlet, thus restricting the return of the valve plate. When the person's head leaves the pillow, the pressure in the balloon suddenly disappears and it rapidly expands, and the air pressure inside the balloon suddenly decreases. At this point, the valve plate, attracted by the negative pressure, overcomes the tension of the self-locking spring and quickly returns to its original position. The centerline of the self-locking spring also crosses the valve plate axis, changing the direction of pull on the valve plate, causing the valve plate to fit tightly against the air intake end. Simultaneously, the valve plate of the air intake valve at the other end of the balloon is lifted by the negative pressure, opening the air intake end of the air intake valve. Outside air quickly enters the balloon, and the balloon returns to its natural state.

[0073] The ninth embodiment: Similar to the third embodiment, the performance of delayed gas output after balloon compression is further enhanced. A hysteresis device 30 is added to the valve plate 28 at the inlet end of the outlet valve 25. For example... Figure 19As shown, the hysteresis device has a magnet 32 ​​mounted on the open side of the air outlet valve plate. The valve plate is made of a mixture of gel material and magnetic powder, and therefore also has magnetic properties. After the valve plate opens, it is attracted by the magnet and prevented from returning to its original position. Of course, the attraction between the magnet and the valve plate must be appropriate, so that the valve plate will quickly return to its original position when the person's head leaves the pillow. At the same time, the valve plate of the balloon air inlet valve is attracted by negative pressure and lifted, opening the air inlet end of the air inlet valve, allowing outside air to quickly enter the balloon, and the balloon returns to its natural state. This example illustrates that there can be various types of hysteresis devices for valve plate-type air outlet valves.

[0074] Tenth embodiment: such as Figure 20 , Figure 21 As shown, both the inlet valve 24 and the outlet valve 25 are ball valves 33. One end of the sleeve 34 of the ball valve is the inlet end 26, and the other end is the outlet end 27. Inside the inlet is a sealing ball 36, behind which a spring 35 rests. The other end of the spring rests on a protrusion on the inner wall of the sleeve 34. When the pillow is not compressed and the balloon remains in its natural state, the inlet end of the inlet valve is blocked by the sealing ball, preventing air from entering. The outlet end of the outlet valve is also blocked by the sealing ball, preventing air from escaping. When a person's head presses against the pillow, the internal pressure of the balloon suddenly increases, the sealing ball at the outlet end of the outlet valve is forced open, and the gas inside the balloon rushes out rapidly. Conversely, when a person's head leaves the pillow, the balloon rapidly expands, the internal pressure drops sharply, the sealing ball of the outlet valve is sucked back to the closed position, and the gas output from the balloon stops. The sealing ball at the inlet end of the inlet valve is also sucked towards the inside of the balloon, and ambient air rapidly enters the balloon.

[0075] For ball valves, both the outlet 27 of inlet valve 24 and the outlet 27 of outlet valve 25 can be used as follows: Figure 20 , Figure 21 As shown, the opening is made on the wall of sleeve 34, bypassing the sealing ball. Alternatively, notches or pipes can be made on both sides of the sealing ball.

[0076] For the ball valve in this example, a hysteresis device is also needed to solve the problem of delayed gas delivery when the balloon stops compressing. Figure 22 A hysteresis device 30 suitable for ball valves is introduced. This hysteresis device is located inside the air outlet valve of the ball valve, specifically, check teeth 37 are provided on the inner wall of the sleeve 34 through which the sealing ball 36 slides. The check teeth consist of multiple raised ridges, forming a rough surface. When the balloon is compressed and the air pressure increases sharply, the sealing ball is pushed open, the air outlet valve opens, and the sealing ball retracts into the rough surface of the check teeth. When the balloon pressure balances, and the pressure on both sides of the sealing ball is equal, the frictional force of the rough surface cancels out the spring's thrust, thus limiting the return of the sealing ball, and the air outlet remains open. Only when the person's head leaves the pillow and the balloon pressure drops sharply is the sealing ball forcibly drawn back, thus achieving the goal of continuous air supply when the pillow is compressed.

[0077] Eleventh embodiment: An improvement upon the foregoing embodiments. For example... Figure 23 , Figure 24 As shown, the upper part of the balloon 3 is equipped with a pressure plate 17, and the lower part is equipped with a bottom plate 21. Both the pressure plate and the bottom plate are rigid plates. A vertical rack 18 is installed under the pressure plate, and a gear 19 that meshes with the rack is mounted on the bottom plate via a bracket 20. A stirring line 22 extending in all directions is mounted on the gear shaft. When the balloon is compressed or expanded, the rack drives the gear and the stirring line to rotate. A shearing blade 23 is installed above the bottom plate of the balloon, and the shearing blade is parallel to and close to the stirring line. The balloon is equipped with an inlet valve 24 and an outlet valve 25. Both the inlet valve and the outlet valve are one-way valves. The outlet valve 25 is connected to an air tube 6. During the compression of the balloon, the inlet valve is closed and the outlet valve is open. During the expansion of the balloon, the outlet valve is closed and the inlet valve is open.

[0078] Clearly, this example combines the structure and performance of the aforementioned embodiments. During use, it can stir and cut the medicinal materials inside the balloon, and can be opened and closed via two one-way valves. All of these actions are performed automatically during the user's natural movements of lying down or getting up, thus further enhancing the product's quality. Moreover, its structure is not complex, making it easy to manufacture, and its application prospects are very promising.

[0079] Twelfth embodiment: Based on the foregoing embodiments, a simple and easy-to-implement equivalent structure is introduced. For example... Figure 25 This refers to the elongated balloon 3 inside the pillowcase. The upper part of the balloon 3 has a pressure plate 17, and the lower part has a base plate 21. Both the pressure plate and the base plate are rigid, and the pressure plate is tightly connected to the inner wall of the pillowcase. A support spring 16 is located inside the balloon; the upper end of the support spring abuts against the pressure plate, and the lower end presses against the bottom surface of the pillowcase. The balloon has an inlet valve 24 and an outlet valve 25, both of which are one-way valves. The outlet valve 25 is connected to an air tube 6. During balloon compression, the inlet valve closes and the outlet valve opens. During balloon expansion, the outlet valve closes and the inlet valve opens. A downward-extending plunger 38 is located in the middle of the pressure plate 17, and the plunger's periphery slides in conjunction with a sliding sleeve 39. A side inlet 42 is opened on one side of the upper middle part of the sliding sleeve, and a side outlet 43 is opened at the lower part of the sliding sleeve. The lower end of the sliding sleeve connects to a base 44, and the lower end of the base connects to the base plate 21. The outer periphery of the sliding sleeve is provided with an elastic conical mesh 41, the outer periphery of which is in contact with the inner wall of the balloon, and the cone point of the elastic conical mesh is connected to the surface between the side inlet and side outlet of the sliding sleeve. Figure 26 It is evident that in its natural state, the lower end of the plunger in balloon 3 is higher than the inlet on the sliding sleeve side. Combined with... Figure 27 As can be seen, when the balloon is compressed, the plunger descends to the lower dead center and contacts the base. A filling port 4 is located on the balloon above the elastic conical mesh, and the filling port is equipped with a sealing cap. Alternatively, a flexible tube can be extended from the filling port to the outside of the pillowcase and then sealed with the cap.

[0080] In use, spices or traditional Chinese medicine can be pulverized into sealed spice balls 40. The diameter of the spice ball should be smaller than the side inlet of the sliding sleeve but larger than the inner diameter of the sliding sleeve. That is, it can enter the inner hole of the sliding sleeve through the side inlet, but cannot slide down through the inner hole of the sliding sleeve. There are various sealing methods for the sealed spice balls, such as plastic sealing or wax sealing, as long as the fragrance cannot be emitted. The sealed spice balls are fed into the balloon through the filling port above, and then fill the top of the elastic conical mesh. Because the surface of the elastic conical mesh is conical, the sealed spice balls will flow to the lowest point. Due to the restriction of the side inlet of the sliding sleeve, normally only one sealed spice ball enters the side inlet of the sliding sleeve and gets stuck between the side inlet and the inner wall of the sliding sleeve. When the pillowcase is pressed down, the pressure plate 17 moves downward, pushing the plunger down along the inner hole of the sliding sleeve. The lower end of the plunger will crush and forcefully push the sealed spice ball down until it is released from the side outlet. Those that cannot be released will be further pulverized on the base, and since the upper part of the base is conical, the pulverized spices and traditional Chinese medicine can be scattered into the balloon. Because the seal of the fragrance ball is broken, the fragrance can be released into the balloon. When the balloon is compressed, the air outlet valve 25 opens, and the fragrance can be released into the user's surroundings through the air tube. When the person finishes resting and their head leaves the pillowcase, the balloon returns to its original shape, the air outlet valve 25 closes, and the air inlet valve 24 opens, allowing air to enter. The sealed fragrance ball on the elastic conical mesh will no longer fall off by itself and will remain on top of the elastic conical mesh.

[0081] The aforementioned sealed fragrance balls are suitable for strongly scented, less durable, and expensive fragrances or herbs. For common fragrances and herbs, the balls can also be inserted through the filling opening at the bottom of the pillowcase. Experiments show that using this method, only one sealed fragrance ball falls into the bladder each time the user presses their head down onto the pillowcase. Afterward, even if the head moves slightly, as long as it doesn't completely leave the pillowcase, the lower end of the plunger cannot return to its original position, and the sealed fragrance ball will not enter the inner hole of the sliding sleeve. Thus, several hundred sealed fragrance balls loaded into the bladder at once can last for a long time. After being completely used up, the bladder can be refilled, with excellent results.

[0082] Thirteenth embodiment: An improvement based on the foregoing embodiments. For example... Figure 28As shown, a pillowcase 1 surrounds the balloon 3. A pressure plate 17 is located on top of the balloon, and the pressure plate is tightly connected to the inner wall of the pillow. The pressure plate is a rigid board, and the space above it is filled with breathable filling material 2. Buckwheat hulls are the best breathable material here. Buckwheat hulls are pyramidal in shape, non-toxic, odorless, and have good breathability, making them an ideal filling material for pillows. Supporting springs 16 are located on both sides of the balloon's exterior. The upper end of the supporting springs abuts against the pressure plate, and the lower end presses against the bottom surface of the pillowcase. This type of pillow provides the same comfort as a traditional pillow. When a person rests, the pressure plate descends smoothly under the pressure of the head, and the balloon is compressed evenly. The aroma of spices and traditional Chinese medicine inside the balloon is released, providing various health benefits. Because the pressure plate operates smoothly, the balloon's movement is better supported, making it suitable not only for elliptical balloons but also for rectangular balloons.

[0083] Based on this, further adoption can be made Figure 29 The illustrated design incorporates a nylon zipper or similar adhesive strip 45 between the pressure plate 17 and the balloon 3, allowing the pressure plate and balloon to pull against each other. Thus, when a person leaves the pillow and the pressure plate moves upwards, the balloon, relying not only on its own elasticity but also on the tension of the spring, quickly expands and returns to its natural state, resulting in more stable and reliable performance.
