Description

Technical Field

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

[0002] The existing pillow includes a pillow body and a mounting groove at the bottom of the pillow body for housing a drug vaporization box. The pillow body has a ventilation pipe bridging the mounting groove and the top surface of the pillow body. The ventilation pipe includes inclined diffusion channels bridging the top wall of the mounting groove and the top surface of the pillow body. The lower ends of the diffusion channels are concentrated on the top wall of the mounting groove, while the upper ends are distributed in various areas of the top surface of the pillow body. Drug-laden gas generated in the drug vaporization box diffuses and is transported to various areas of the top surface of the pillow body through the diffusion channels for absorption by the user through respiration. However, each diffusion channel is a straight tube with an inclined diffusion pattern. Because the diffusion channels are inclined within the pillow body, the top of the pillow body undergoes vertical compression deformation when subjected to downward pressure, causing the diffusion channels to become compressed and blocked. This prevents the drug-laden gas from being smoothly expelled through the diffusion channels, affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a pillow with good pressure resistance. The pillow has an inclined extension channel and a vertical channel inside, and a deformation buffer is formed above the extension channel. This effectively reduces the deformation amplitude of the extension channel caused by the deformation of the pillow body, thereby ensuring that the medicine-carrying gas can be smoothly discharged.

[0004] This utility model is achieved through the following means: a pillow with good pressure resistance, including a pillow body and a drug vaporization box disposed at the bottom of the pillow body. The bottom of the pillow body is provided with an installation groove for embedding the drug vaporization box. A ventilation pipe is connected between the installation groove and the top surface of the pillow body. The ventilation pipe includes an extension channel that communicates with the installation groove and extends obliquely upward, and a vertical channel that connects the extension channel and the top surface of the pillow body. The extension channel is disposed in the middle of the pillow body. The area of ​​the pillow body above the extension channel forms a deformation buffer part to reduce the deformation amplitude of the extension channel when the pillow body is compressed. The pillow features inclined extension channels and vertical channels, with a deformation buffer above the extension channels. The deformation buffer reduces the downward pressure on the extension channels through its own deformation, thereby effectively reducing the deformation amplitude of the extension channels caused by the pillow body. This ensures that the drug-containing gas generated by the drug vaporizer can diffuse to all sides through the extension channels and then be transported upwards to various areas above the pillow body through the corresponding vertical channels, facilitating absorption by the user through breathing and achieving sleep aid and anti-snoring effects.

[0005] Preferably, the vertical channel is vertically oriented, with its upper end exposed on the top surface of the pillow body and its lower end connected to the extended channel, thereby reducing the deformation amplitude of the vertical channel when the pillow body is compressed. The vertical channel vertically passes through the deformation buffer section, and the axial direction of the vertical channel is consistent with the compression direction of the deformation buffer section. This ensures that the radial cross-section of the vertical channel maintains a constant profile when the deformation buffer section is compressed and deformed, thus ensuring that the flow rate of the drug-carrying gas in the vertical channel does not decrease due to the compression deformation of the deformation buffer section, and ensuring that the drug-carrying gas can be effectively diffused.

[0006] Preferably, the extended channel has the same included angle A with the horizontal plane, where 10°≤A≤35°. The inclined setting of the extended channel not only facilitates the horizontal diffusion of the drug-carrying gas, ensuring that the drug-carrying gas can be diffused to all areas of the pillow body, but also controls the distance between it and the top surface of the pillow body by tilting upwards, shortens the transportation distance of the drug-carrying gas in the ventilation pipeline by shortening the length of the vertical pipe, and thus improves the diffusion effect by reducing flow resistance.

[0007] Preferably, the mounting slot is located at the center of the bottom of the pillow body, and the bottom port of the extension channel is opened on the top wall of the mounting slot. The top port extends obliquely outward to each section of the pillow body's periphery, so that the vertical channels are distributed. The mounting slot provides space for installing the drug vaporization box, and the top of the mounting slot has obliquely upward extension channels extending to each section of the pillow body's periphery, ensuring that the drug-containing gas generated by the drug vaporization box can diffuse in all directions through the extension channels.

[0008] Preferably, the top of the mounting groove is provided with a transverse channel that communicates with it and extends along the width direction of the pillow body. Each section of the transverse channel is provided with a corresponding extension channel and a transverse channel. The transverse channel receives the drug-carrying gas from the mounting groove and diffuses it into each extension channel along the width direction of the pillow body. The drug-carrying gas is concentrated and transported through the transverse channel with a large cross-sectional profile, ensuring that the drug-carrying gas can be uniformly diffused in the width direction.

[0009] Preferably, the extended channels and the transverse channels are arranged perpendicular to each other, and each extended channel has the same setting direction, which facilitates processing and ensures that the extended channels uniformly cover the pillow body, thereby improving the uniformity of drug-carrying gas diffusion.

[0010] Preferably, the extended channels located on the transverse channel are staggered and tilted in opposite directions at intervals, so that the extended channels form a grid pattern in the same plane. In the projection along the width of the pillow body, the extended channels have the same tilt angle A with the horizontal plane. In the vertical projection, adjacent extended channels on the transverse channel have opposite tilt directions, allowing adjacent extended channels to intersect each other, thereby forming a grid structure and effectively improving diffusion uniformity.

[0011] Preferably, the transverse channel is a single channel located at the centerline of the pillow body. Extended channels extending towards the front and rear edges of the pillow body are respectively provided on both sides of the transverse channel. The transverse channel, with its large radial cross-sectional profile, effectively reduces the flow resistance of the drug-carrying gas within it, ensuring a uniform concentration of drug-carrying gas in each section of the transverse channel and its delivery to all extended channels along its path. The front wall of the transverse channel has an extended channel extending towards the front edge of the pillow body, and the rear wall has an extended channel extending towards the rear wall of the pillow body, allowing the drug-carrying gas to be delivered to all extended channels through the single transverse channel.

[0012] Preferably, the transverse channels are two parallel channels located at the front and rear of the top of the mounting groove. These transverse channels extend in opposite directions to form extension channels facing the front and rear edges of the pillow body, respectively. Both transverse channels are connected to the top of the mounting groove. The front transverse channel extends forward to form an extension channel facing the front edge of the pillow body, while the rear transverse channel extends backward to form an extension channel facing the rear edge of the pillow body. Increasing the number of transverse channels improves the transverse diffusion efficiency of the drug-carrying gas, and the separate transverse channels reduce the probability of simultaneous compression and blockage.

[0013] Preferably, the extended channels are equidistantly distributed along the transverse channels, thereby ensuring that each area of ​​the pillow body in the vertical projection has a corresponding extended channel, and thus ensuring that each area above the pillow body can obtain the drug-laden gas from the corresponding extended channel through the vertical channel.

[0014] Preferably, the vertical channels are equidistantly distributed along the corresponding extended channels. The extended channels can discharge the drug-laden gas through multiple vertical channels along the way, thereby improving the diffusion uniformity by increasing the density of the vertical channels.

[0015] Preferably, the extended channels correspond one-to-one with the vertical channels, and each extended channel is provided with only one vertical channel to ensure that the drug-carrying gas output from each vertical channel has the same airflow rate and concentration, preventing uneven flow rate and concentration caused by the extension channel being provided with multiple vertical channels.

[0016] Preferably, the front and rear parts of the top of the pillow body are raised upwards respectively, and the extension channel is inclined to reduce the fluctuation range of the height difference between each section of the extension channel and the corresponding area of ​​the top of the pillow body. This ensures that the thickness of the deformation buffer part in each area of ​​the pillow body is within the preset range, which can not only ensure the reliability of the protection of the extension channel, but also effectively shorten the length of the vertical pipe and improve the diffusion effect of the drug-carrying gas.

[0017] Preferably, the pillow body is a one-piece structure, with the vertical, horizontal, and extended channels all being straight tubes, and at least one end exposed on the pillow body surface. The pillow body is integrally formed, effectively improving processing efficiency and reducing processing costs. The straight vertical, horizontal, and extended channels are formed on the one-piece pillow body, creating ventilation pipes spanning the top of the mounting groove and the top surface of the pillow body, facilitating batch processing. The vertical channels on the pillow body are all vertically oriented, the horizontal channels are all horizontally oriented, and the extended channels also have the same orientation, effectively reducing the difficulty of drilling and improving processing efficiency.

[0018] Preferably, the pillow body includes an upper layer and a lower layer that can be vertically stacked and fixed together. The mounting groove is formed in the middle of the lower layer. The upper and lower layers are stacked and enclosed to form a transverse channel and an extension channel. The upper and lower layers are processed and assembled into the pillow body independently. The contours of the bottom surface of the upper layer and the top surface of the lower layer can be formed differently during independent processing, and local ventilation channels are formed during stacking and assembly, including but not limited to the transverse channel and the extension channel, effectively reducing the processing difficulty.

[0019] Preferably, the transverse channels are three in number: a central channel and side channels on either side of the central channel. The extended channels include an upper channel formed by extending forward and backward from both sides of the central channel, and a lower channel formed by extending backward from the side channels. The upper and lower channels are staggered in height, and their vertical projections are inclined in opposite directions, connecting at their intersection via the transverse channels. The central and side channels are parallel and positioned from front to back. The two sides of the central channel extend forward and backward respectively to form upward-sloping upper channels. The side channels in front of the central channel extend forward to form upward-sloping lower channels, and the side channels behind the central channel extend backward to form upward-sloping lower channels. The upper channels are located above the lower channels, and the angle between the upper channels and the horizontal plane is greater than the angle between the lower channels and the horizontal plane. This staggered height and non-direct connection between the upper and lower channels effectively utilizes the space within the pillow. In the vertical projection, the upper and lower extension channels have opposite tilt directions, so that the upper and lower extension channels coincide in the vertical projection. The vertical channel can be set at the intersection of the upper and lower extension channels and realize the connection between the upper and lower extension channels.

[0020] Preferably, the vertical projections of the upper and lower extension channels are in a grid pattern that is perpendicular to each other, ensuring that the intersection points of the upper and lower extension channels on the vertical projection are distributed in a matrix shape, which facilitates the uniform setting of the vertical channels.

[0021] Preferably, the vertical channel is located at the intersection of the vertical projections of the upper and lower extension channels. The lower end of the vertical channel is connected to the lower extension channel, the middle section passes through the upper extension channel, and the upper end is exposed on the top surface of the pillow body. The vertical channel, by being vertically opened, serves to connect the upper and lower extension channels, ensuring that the drug-laden gas in the upper and lower extension channels can diffuse upwards to the space above the pillow body, and ensuring that the drug-laden gas in the ventilation pipeline can be smoothly discharged.

[0022] The beneficial effects of this utility model are as follows: An inclined extension channel and a vertical channel are set inside the pillow, and a deformation buffer part is formed above the extension channel. The deformation buffer part can reduce the downward pressure on the extension channel through its own deformation, thereby effectively reducing the deformation amplitude of the extension channel caused by the deformation of the pillow body. This ensures that the drug-containing gas generated by the drug vaporization box can diffuse to the surroundings through the extension channel, and then be transported upward to various areas above the pillow body through the corresponding vertical channel, so that the user can absorb it through breathing and obtain the effects of sleep aid and anti-snoring.

[0035] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] This embodiment provides a pillow.

[0038] like Figure 1 The pillow shown includes a pillow body 1 and a drug vaporization box 2 disposed at the bottom of the pillow body 1. The bottom of the pillow body 1 is provided with a mounting groove 3 for embedding the drug vaporization box 2. A ventilation pipe is connected between the mounting groove 3 and the top surface of the pillow body 1. The ventilation pipe includes an extension channel 4 that communicates with the mounting groove 3 and extends obliquely upward, and a vertical channel 5 that connects the extension channel 4 and the top surface of the pillow body 1. The extension channel 4 is disposed in the middle of the pillow body 1. The area of ​​the pillow body 1 above the extension channel 4 forms a deformation buffer to reduce the deformation amplitude of the extension channel 4 when the pillow body 1 is compressed. An inclined extension channel 4 and a vertical channel 5 are set inside the pillow, and a deformation buffer is formed above the extension channel 4. The deformation buffer can reduce the downward pressure on the extension channel 4 through its own deformation, thereby effectively reducing the deformation amplitude of the extension channel 4 caused by the deformation of the pillow body 1. This ensures that the drug-containing gas generated by the drug vaporization box 2 can diffuse to the surroundings through the extension channel 4, and then be transported upward to various areas above the pillow body 1 through the corresponding vertical channel 5, so that the user can absorb it through breathing and obtain the effects of sleep aid and anti-snoring.

[0039] In this embodiment, the mounting groove 3 is located at the center of the bottom of the pillow body 1, and the bottom port of the extension channel 4 is opened on the top wall of the mounting groove 3, while the top port extends obliquely outward to various sections around the periphery of the pillow body 1 (e.g., Figure 2 As shown), the vertical channels 5 are distributed in a dispersed manner. The mounting groove 3 is located in the center of the pillow body 1. The lower end of the extension channel 4 is connected to the top of the mounting groove 3, and the higher end extends to each section of the periphery of the pillow body 1, so that the extension channel 4 radiates outward from the mounting groove 3 as the center, ensuring that the vertical projection of the extension channel 4 can evenly cover the vertical projection of the pillow body 1.

[0040] In use, the drug-containing gas generated in the drug vaporization box 2 is transported to each extension channel 4 through the top of the mounting groove 3, and then transported to the space above the pillow body 1 through the vertical channels 5 set on each extension channel 4. This ensures that each area above the pillow body 1 can obtain drug-containing gas through the corresponding vertical channels 5 and diffuse it to the surrounding area, ensuring that the space above the pillow body 1 accumulates drug-containing gas with a balanced concentration, which is convenient for the user to absorb through breathing, thus achieving the effects of sleep aid and anti-snoring.

[0041] In this embodiment, the front and rear parts of the top surface of the pillow 1 are raised upwards to ensure effective support for the user's head and neck when lying down. The extension channel 4 is inclined to reduce the fluctuation range of the height difference between the corresponding areas of each section of the extension channel 4 and the top surface of the pillow 1. This ensures that each section of the extension channel 4 has a deformation buffer of appropriate thickness, and the deformation of the deformation buffer itself offsets part of the weight from the user's head and neck, thereby reducing the radial deformation amplitude of the extension channel 4. This ensures that the drug-carrying gas flows smoothly through the extension channel 4, and also limits the distance between each section of the extension channel and the top surface of the pillow 1 within a preset range, thereby shortening the length of the vertical channel 5 and improving the diffusion effect by reducing flow resistance. The extension channel 4 has the same angle A with the horizontal plane, 10°≤A≤35°. The parameter A can be 10°, 15°, 20°, 30°, 35°, etc., and all should be considered as specific implementations of this embodiment.

[0042] In this embodiment, the vertical channel 5 is vertically oriented, with its upper end exposed on the top surface of the pillow body 1 and its lower end connected to the extension channel 4, thereby reducing the deformation amplitude of the vertical channel 5 when the pillow body 1 is compressed. The vertical axis of the vertical channel 5 is aligned with the force direction of the deformation buffer section, ensuring that the radial cross-sectional profile of the vertical channel 5 does not change when the deformation buffer section is compressed, thus ensuring the flow efficiency of the vertical channel 5.

[0043] In this embodiment, the pillow body 1 is a one-piece structure (e.g., Figure 3 As shown in the figure, the vertical channel 5 and the extended channel 4 are both straight tubes, and at least one end is exposed on the surface of the pillow body 1, which facilitates the formation of the vertical channel 5 and the extended channel 4 through the opening, thereby improving the processing convenience.

[0044] In this embodiment, various drugs, such as traditional Chinese medicine, essential oils, and aromatherapy, can be placed in the drug evaporation box 2. The drug form can be solid, paste, or even liquid. When the drug is liquid, it can be mixed with cotton fibers to form a liquid-carrying cotton ball. All of these should be considered as specific implementation methods of this embodiment.

[0045] Example 2:

[0046] Compared to Example 1, this example provides another type of pillow.

[0047] like Figure 4 As shown, the top of the mounting groove 3 is provided with a transverse channel 6 that communicates with it and extends along the width direction of the pillow body 1. Each section of the transverse channel 6 is provided with a corresponding extension channel 4 and a transverse channel 6. The middle part of the transverse channel 6 communicates with the top of the mounting groove 3 and connects with the dispersed extension channels 4 along its path, so that the drug-laden gas in the mounting groove 3 can be transported to each extension channel 4 through the transverse channel 6, and then diffused into the space above the pillow body 1 through the corresponding vertical channel 5.

[0048] In this embodiment, the transverse channel 6 is a single channel located at the center line of the pillow body 1. The transverse channel 6 extends through the pillow body 1 along its width. Extension channels 4 (e.g., extending towards the front and rear edges of the pillow body 1) are respectively provided on both sides of the transverse channel 6. Figure 5 As shown), the eye pillow body 1 has an extension channel 4 extending obliquely upward on both sides of the channel. The extension channel 4 and the transverse channel 6 are perpendicular to each other. The extension channels 4 located on the same side of the transverse channel 6 are equidistant from each other and laid in the same inclined plane, which facilitates batch processing.

[0049] In this embodiment, the extended channels 4 are equidistantly distributed along the transverse channels 6, and the vertical channels 5 are equidistantly distributed along the corresponding extended channels 4. Each extended channel 4 is provided with equidistantly distributed vertical channels 5. Since the distance between adjacent extended channels 4 is the same, and the distance between adjacent vertical channels 5 on the same extended channel 4 is the same, the vertical channels 5 are uniformly distributed in a matrix at the upper port of the top surface of the pillow body 1, effectively improving the diffusion uniformity of the drug-carrying gas.

[0050] In this embodiment, the extended channel 4 corresponds one-to-one with the vertical channel 5 (e.g., Figure 6 As shown, each extended channel 4 is provided with only one vertical channel 5 to ensure that the drug-carrying gas in the extended channel 4 is discharged inside and outside through the corresponding vertical channel 5, and to ensure that each vertical channel 5 outputs an equal amount and concentration of drug-carrying gas. This should also be considered a specific embodiment of this utility model. In the embodiment, the positions of the vertical channels 5 on adjacent extended channels 4 can change sequentially and regularly to ensure that the vertical channels 5 are distributed in various areas of the top surface of the pillow body 1.

[0051] In this embodiment, the pillow body 1 is an integral structure, and the transverse channel 6, vertical channel 5 and extension channel 4 are all straight tubes, with at least one end exposed on the surface of the pillow body 1, which facilitates the formation of the transverse channel 6, vertical channel 5 and extension channel 4 through openings, thereby improving processing convenience.

[0052] In this embodiment, the transverse channels 6 are two parallel channels located at the front and rear of the top of the mounting groove 3. The transverse channels 6 extend in the opposite direction to form extension channels 4 facing the front and rear edges of the pillow body 1, which should also be considered as a specific implementation of this embodiment.

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

[0054] Example 3:

[0055] Compared to Example 2, this example provides another type of pillow.

[0056] like Figure 7 As shown, the pillow body 1 includes an upper layer and a lower layer that can be vertically stacked and fixed together. The mounting groove 3 is formed in the middle of the lower layer. The upper and lower layers are stacked and enclosed to form a transverse channel 6 and an extension channel 4. The upper and lower layers are processed independently and then stacked and bonded together to form the pillow body 1. The top surface of the lower layer and the bottom surface of the upper layer can form a unique contour when processed independently, and form the transverse channel 6 and / or the extension channel 4 when stacked and assembled, effectively eliminating the need for drilling to form the transverse channel 6 and the extension channel 4, and improving processing convenience.

[0057] The other structures and effects of the pillow described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.

[0058] Example 4:

[0059] Compared to Example 2, this example provides another type of pillow.

[0060] like Figure 8 As shown, the extended channels 4 located on the transverse channel 6 are staggered and inclined in opposite directions at intervals, so that the extended channels 4 form a grid in the same plane. The extended channels 4 are all arranged in the same inclined plane, so that the extended channels 4 can be directly connected by interleaving each other. The vertical channel 5 is located at the intersection of the extended channels 4, effectively receiving the drug-carrying gas from two extended channels 4, thereby improving the diffusion efficiency of the drug-carrying gas.

[0061] The other structures and effects of the pillow described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.

[0062] Example 5:

[0063] Compared to Example 4, this example provides another type of pillow.

[0064] like Figure 9As shown, the transverse channels 6 consist of three channels: a central channel 9 and side channels 10 located on either side of the central channel 9. The extended channels 4 include an upper extension channel 12 formed by extending forward and backward from both sides of the central channel 9, and a lower extension channel 11 formed by extending backward from the side channels 10. The upper extension channel 12 and the lower extension channel 11 are staggered in height, and their vertical projections are inclined in opposite directions and connected at their intersection by a vertical channel 5. The staggered height of the upper extension channel 12 and the lower extension channel 11 prevents them from being directly connected. A vertical channel 5 is provided at the intersection of the vertical projections of the upper extension channel 12 and the lower extension channel 11, allowing them to be connected. This facilitates the simultaneous reception of the drug-carrying gas from the upper extension channel 12 and the lower extension channel 11 by the vertical channel 5, effectively improving the diffusion efficiency of the drug-carrying gas.

[0065] In this embodiment, the vertical projections of the upper extension channel 12 and the lower extension channel 11 form a grid pattern that is perpendicularly intersecting with each other (e.g., Figure 10 As shown), this arrangement makes each grid square, ensuring that there is the same spacing between adjacent upper extension channels 12 and adjacent lower extension channels 11. This facilitates synchronous processing of the upper extension channels 12 and the lower extension channels 11, and also effectively reduces the differences in the concentration and flow rate of the drug-carrying gas in each vertical channel 5.

[0066] In this embodiment, the vertical channel 5 is located at the intersection of the vertical projections of the upper extension channel 12 and the lower extension channel 11 (e.g., Figure 11 As shown, the lower end of the vertical channel 5 is connected to the lower extension channel 11, the middle section passes through the upper extension channel 12, and the upper end is exposed on the top surface of the pillow body 1. The vertical channel 5 can be vertically opened to connect the upper extension channel 12 and the lower extension channel 11, ensuring that the drug-laden gas in the upper extension channel 12 and the lower extension channel 11 can diffuse upward to the space above the pillow body 1, and ensuring that the drug-laden gas in the ventilation pipeline can be smoothly discharged.

[0067] The other structures and effects of the pillow described in this embodiment are the same as those in Embodiment 4, and will not be repeated here.
