Description

Technical Field

[0001] The invention relates to the technical field of pillows, in particular to a washable and anti-aging latex pillow. Background Art

[0002] Compared with ordinary pillows, latex pillows can provide better support and elasticity, thereby better maintaining the natural curve of the user's head and neck, thereby improving the user's cervical and lumbar pain; at the same time, latex pillows are made of latex material and have better antibacterial effects than ordinary pillows, thereby providing users with a healthier and cleaner sleeping environment.

[0003] Although latex pillows have better antibacterial effects than ordinary pillows, after a certain period of use, dandruff and grease will still remain on the pillow, so the latex pillow needs to be cleaned to ensure its cleanliness; during the washing process, the latex pillow will absorb water and swell, and it will easily deform or lose its original elasticity after drying, resulting in a decrease in the support and elasticity of the latex pillow; not only that, after a certain period of use, the latex material is easily affected by external factors such as air, sunlight or sweat, causing it to deteriorate, harden or deform, which will also cause a decrease in the support and elasticity of the latex pillow; for this reason, some latex pillow products add anti-aging agents to natural latex during production, and provide a waterproof coating on the surface of the latex pillow to improve the anti-aging and water-washing resistance of the latex pillow.

[0004] The above-mentioned emulsified pillow is provided with a waterproof coating on the surface, and an anti-aging agent is added to the natural latex. Although the support and elasticity of the latex pillow are guaranteed after washing or long-term use, the air permeability of the latex pillow is correspondingly reduced; In response to this problem, the prior art provides some solutions. For example, the utility model patent with patent application number 202223522817.4 provides a breathable and sweat-proof latex pillow. The solution provided by the patent is: a breathable inner cavity is provided in the latex pillow. When the latex pillow is subjected to downward pressure, the breathable inner cavity is squeezed and deformed, and the positive pressure gas in the breathable inner cavity is discharged out of the latex pillow, thereby achieving heat dissipation and breathability performance; and a spiral elastic column is provided in the inner wall to improve the support for the breathable inner wall, thereby improving the breathability effect when the airflow flows, and at the same time improving the elasticity of the latex pillow body and not easy to sag; although this technical solution can improve the breathability effect of the latex pillow, it also increases the overall weight and material cost of the latex pillow. At the same time, the latex pillow has structural parts, which is not convenient for users to disassemble and clean it. Summary of the invention

[0005] The purpose of the present invention is to provide a washable anti-aging latex pillow to solve the problem that the washable anti-aging latex pillow has poor air permeability and affects the sleep comfort of the user; at the same time, it solves the problem that the existing breathable emulsified pillow has high material cost, large overall weight, and is difficult to disassemble and clean.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A washable and anti-aging latex pillow comprises a pillowcase and a pillow core, wherein the pillowcase is wrapped around the outer side of the pillow core, the pillow core is made of latex material, and antioxidants, anti-ultraviolet agents, mildew inhibitors, stabilizers, waterproof agents and surfactants are added to the latex material of the pillow core to improve the anti-aging and washability of the pillow core, wherein the content proportions of various additives in the pillow core are: antioxidants account for 0.3% to 1.0%, anti-ultraviolet agents account for 0.5% to 1.0%, mildew inhibitors account for 0.1% to 0.5%, stabilizers account for 0.1% to 1.0%, waterproof agents account for 0.5% to 2.0%, and surfactants account for 0.1% to 1.0%; and in order to further improve the washability of the pillow core, a layer of water-based coating is coated on the surface of the pillow core, and the thickness of the water-based coating is 0.1mm to 0.5mm.

[0008] Specifically, a plurality of ventilation holes are provided on the upper surface of the pillow core, a weight reduction cavity is provided on the bottom of the pillow core, the ventilation holes are connected with the weight reduction cavity, a bracket is provided in the weight reduction cavity, a movable part is provided on the upper side of the bracket, the movable part is unconstrained in the vertical direction, an airbag is provided on the lower end surface of the movable part, and the airbag is connected with the ventilation holes.

[0009] By arranging air holes on the upper surface of the pillow core, and the air holes completely penetrate the lower end surface of the pillow core, the air permeability of the pillow core is improved; at the same time, by arranging a bracket and an air bag in the pillow core, when the pillow core is subjected to downward pressure, the pillow core is deformed downward due to the downward pressure, and the movable part of the bracket is forced to move downward. During the downward movement of the movable part, the air bag is squeezed, and the gas pressure in the air bag increases and is discharged from the air holes, thereby forming an airflow on the upper side of the pillow core, improving the gas flowability of the upper surface of the pillow core, and then improving the comfort of the latex pillow.

[0010] Furthermore, by arranging a weight-reducing cavity in the pillow core, the weight is reduced compared to a solid pillow core. At the same time, by arranging a bracket in the pillow core, the bracket limits the minimum downward height of the latex pillow. When the movable part is pressurized and presses the airbag down to the lower dead point, the movable part and the bracket are rigidly connected, thereby avoiding the collapse of the latex pillow. Moreover, the bracket can also be set as a cavity structure, thereby ensuring the overall support of the latex pillow and reducing the material cost and overall weight of the pillow core.

[0011] Preferably, a movable gap is provided on the front side of the bracket, and the movable gap separates the bracket into a supporting part and a movable part. The movable part is located on the upper side of the movable gap, and the rear end of the movable part is connected to the supporting part. The movable part is made of elastic material, and a fixing groove is provided on the lower end surface of the movable part. The fixing groove extends into the supporting part, and the airbag is installed in the fixing groove.

[0012] By setting the movable gap on the front side of the bracket, the material cost of the bracket and the overall weight of the latex pillow are further reduced, and the movable part and the supporting part are an integrated structure, which ensures the integrity of the bracket and facilitates the user to disassemble and assemble the latex pillow; the bracket can be optionally made of any of the materials selected from polycarbonate, polyethylene, polypropylene or polyester. This type of material has strong chemical resistance and is not easy to cause allergic reactions to users. At the same time, this type of material has good strength properties to ensure the supporting performance of the bracket, and this type of material has strong rebound toughness and elasticity, and can rebound after the pillow core loses pressure, thereby resetting the airbag, ensuring that the airbag is squeezed again after the pillow core is pressurized next time, so that the high-pressure gas in the airbag is discharged through the air vents, thereby improving the gas circulation on the upper surface of the pillow core and improving the comfort of the latex pillow.

[0013] Preferably, a raised portion is provided on the front side of the upper end surface of the pillow core, and the raised portion is higher than the average height of the upper end surface of the pillow core. The upper end surface of the raised portion is a curved surface with low front and rear ends and a raised middle part. The height of the movable gap is H1, and the raised height of the raised portion is H2, wherein H2≥H1.

[0014] By arranging a protrusion on the pillow core, when the user uses the pillow core to sleep, the protrusion supports the user's neck position to avoid the user's neck position being in a suspended state, thereby ensuring the pillow core's supporting effect on the user; at the same time, by setting the movable gap and the protrusion height of the protrusion to H2≥H1, when the user presses down on the pillow core, the movable part moves downward under the action of the downward pressure, and the front end height of the bracket drops. The protrusion compensates for the dropped active gap height at the front end of the bracket, thereby ensuring the latex pillow's supporting effect on the user's neck position when the user uses the latex pillow, thereby improving the comfort of the latex pillow.

[0015] Preferably, the number of the fixing grooves is at least 3, and an isolation groove is provided between adjacent isolation grooves. The isolation groove completely penetrates the movable part in the vertical direction, and the width of the isolation groove is the same as the width of the protruding part.

[0016] By arranging a plurality of fixing grooves and a plurality of air bags, and arranging isolation grooves between the isolation grooves, when the user changes his sleeping position, along with the lateral movement of the user's head, part of the air bags are pressed down under the action of the gravity of the user's head, and at the same time, part of the air bags are converted from a pressed state to a depressurized state, the internal pressure of the pressed air bags increases, and the high-pressure gas in the pressed air bags is discharged through the air holes, thereby improving the gas circulation on the upper surface of the pillow core; the interior of the air bag converted from a pressed state to a depressurized state is in a negative pressure state, so that the external gas enters the depressurized air bag; compared with a single air bag, this solution uses the changes in the sleeping position of the user during sleep to complete the air intake or exhaust of part of the air bags, thereby improving the gas circulation on the upper surface of the pillow core during sleep, thereby improving the comfort of the latex pillow.

[0017] Preferably, a guide surface is provided on the upper surface of the bracket, and the guide surface is in an arc shape with the front and rear parts convex and the middle part concave, and the lowest point of the arc-shaped guide surface is located in the middle of the bracket. A mounting groove is provided on the guide surface, and the mounting groove completely runs through the length direction of the bracket, and the lowest point of the guide surface is located in the mounting groove. A water absorbent strip is provided in the mounting groove, and the water absorbent strip is made of any one of the materials including polymer absorbent resin, seaweed silicon or bamboo fiber.

[0018] By setting the guide surface and the water-absorbing strip, the sweat or saliva produced by the user during sleep enters the ventilation holes through the pillowcase, and then remains on the guide surface. Under the guiding effect of the arc-shaped guide surface, the sweat or saliva finally flows to the water-absorbing strip, thereby ensuring the dryness of the latex pillow. The water-absorbing strip is made of absorbent resin, seaweed silicon or bamboo fiber, which is beneficial to reduce the growth of bacteria, thereby maintaining the hygiene of the latex pillow. At the same time, with the split design of the pillow core and the bracket, it is convenient for the user to disassemble and assemble the pillow core and the bracket, and to clean or replace the water-absorbing strip, thereby ensuring the hygiene of the latex pillow.

[0019] Preferably, the lower end surfaces of the plurality of mounting grooves are each provided with two through holes extending to the bottom of the bracket, the lower end surface of the airbag is provided with an air inlet and an air outlet, the air inlet and the air outlet are respectively located in the two through holes, the air outlet is connected with the air vent, the air inlet and the air outlet are respectively provided with an air inlet check valve and an air outlet check valve, the passing direction of the air inlet check valve is from the outside of the airbag to the inside of the airbag, and the passing directions of the air inlet check valve and the air outlet check valve are opposite.

[0020] Through the arrangement of the air inlet, the air outlet, the air inlet one-way valve and the air outlet one-way valve, when the airbag is pressurized, the positive-pressure gas in the airbag can only be discharged through the air outlet, and when the airbag loses pressure, the gas outside the airbag can only enter the airbag through the air inlet. Moreover, since the air inlet and the air outlet are both arranged on the lower side of the bracket, sweat or saliva is prevented from entering the airbag and breeding bacteria, thereby ensuring the cleanliness of the gas discharged from the airbag, ensuring the dryness and cleanliness of the gas while ensuring the gas flowability on the upper surface of the latex pillow.

[0021] Preferably, the bracket is provided with an exhaust hole coaxial with the air vent, the exhaust hole is connected with the air vent, a channel groove is opened on the lower end surface of the bracket, two ends of the channel groove are respectively connected with the air outlet and the air vent, and a sealing sheet is also provided on the lower end surface of the bracket, the sealing sheet is completely fitted with the lower end surface of the bracket, and a gas channel is formed between the channel groove and the sealing sheet.

[0022] By setting the channel groove and the sealing sheet, a gas channel is formed on the lower side of the bracket, and the two ends of the gas channel are connected to the air outlet and the exhaust hole respectively. When the airbag is pressurized, the positive pressure gas in the airbag is discharged into the gas channel through the air outlet, reaches the exhaust hole through the gas channel, and then is discharged into the air vent from the exhaust hole, and finally is discharged to the upper surface of the pillow core from the air vent; the sealing sheet and the bracket are bonded to ensure the integrity of the bracket and facilitate the user to disassemble and assemble the pillow core and the bracket; at the same time, by arranging the exhaust hole on the bracket and setting the passing area of ​​the exhaust hole to be smaller than the passing area of ​​the air outlet, the effect of slow exhaust can be achieved, thereby increasing the flow time of gas on the upper surface of the pillow core.

[0023] Preferably, the sealing sheet includes a bonding portion and an expansion portion, the expansion portion is made of elastic material, and the vertical projection of the air vent is completely within the vertical projection plane of the expansion portion, the maximum volume between the expansion portion and the lower end surface of the bracket after expansion is V1, and the maximum compression volume of the airbag is V2, wherein 6≤V1 / V2≤8.

[0024] After the latex pillow is manufactured, the passing area ratio of the exhaust hole and the air outlet is a constant value, that is, when the airbag is pressed down, the gas circulation time on the upper surface of the pillow core is a constant value. In addition, when the airbag is subjected to downward pressure, if the positive pressure gas in the airbag cannot be discharged in time, the protrusion will slowly drop as the pressure time increases until the movable part is limited by the supporting part, and the positive pressure gas in the airbag is completely discharged from the airbag. At this time, there is no gas flow on the upper surface of the pillow core; and when the user changes his sleeping position, the compressed airbag will also slowly sink, affecting the user's experience. By setting a pressure relief valve on the sealing sheet, the user can easily fall into the airbag and sleep in the airbag. A bonding part and an expansion part are arranged, and after the airbag is pressurized, the positive-pressure gas in the airbag is completely discharged out of the airbag, and the expansion part expands under the action of the positive-pressure gas, thereby reducing the discharge time of the airbag when under pressure, improving the response speed of the latex pillow, and improving the comfort of the latex pillow; and in conjunction with the air outlet one-way valve, the positive-pressure gas discharged out of the airbag cannot flow back into the airbag, thereby ensuring the gas flow on the upper surface of the pillow core and improving the comfort of the latex pillow; further, if the user wants to improve the exhaust effect of the pillow core, the airbag can be repeatedly pressed to increase the gas volume between the expansion part and the bracket, thereby extending the gas flow time on the upper surface of the pillow core.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention improves the air permeability of the pillow core by arranging air holes on the upper surface of the pillow core, and the air holes completely penetrate the lower end surface of the pillow core; and by arranging a bracket and an air bag in the pillow core, when the pillow core is subjected to downward pressure, the movable part is forced to move downward and squeeze the air bag, the gas pressure in the air bag increases, and is discharged from the air holes, thereby forming an air flow on the upper side of the pillow core, improving the gas flowability of the upper surface of the pillow core, and further improving the comfort of the latex pillow.

[0027] 2. The present invention provides a plurality of fixed grooves and a plurality of air bags, and provides isolation grooves between the isolation grooves. When the user changes his sleeping position, along with the lateral movement of the user's head, some of the air bags are pressed down under the action of the gravity of the user's head, and at the same time, some of the air bags are converted from a pressed state to a depressurized state. The internal pressure of the pressed air bags increases, and the high-pressure gas in the pressed air bags is discharged through the air holes, thereby improving the gas flowability on the upper surface of the pillow core during sleep, thereby improving the comfort of the latex pillow.

[0028] 3. The present invention arranges an adhesive portion and an expansion portion on the sealing sheet, and cooperates with the air outlet one-way valve of the airbag. After the airbag is pressurized, the positive pressure gas in the airbag is completely discharged out of the airbag, and the expansion portion expands under the action of the positive pressure gas, thereby improving the response speed of the latex pillow. If the user wants to improve the exhaust effect of the pillow core, the airbag can be pressed repeatedly to increase the air volume between the expansion portion and the bracket, thereby extending the gas flow time on the upper surface of the pillow core and improving the comfort of the latex pillow.

[0044] The working principle of the washable latex pillow provided by the present invention will be specifically described below in conjunction with the state diagram:

[0045] See also Figure 5 and Figure 8When the user falls asleep, the head lies on the pillow core 2, and the protrusion 202 moves downward under the action of the gravity of the head. The protrusion 202 drives the movable part 303 to move downward during the downward movement. When the movable part 303 moves downward, the airbag 4 is pressurized, and the gas pressure in the airbag 4 increases; at this time, the inlet check valve 403 is in the closed state, and the outlet check valve 404 is in the connected state. The positive pressure gas in the airbag 4 can only pass through the outlet check valve 404 and the outlet 402. The positive pressure gas discharged from the airbag 4 flows to the exhaust hole 3022 in the gas channel 3023, and the positive pressure gas flowing to the exhaust hole 3022 enters the air vent 201 through the exhaust hole 3022. Since the passing area of ​​the exhaust hole 3022 is smaller than that of the outlet port 402, and the outlet port 402 is provided with an outlet check valve 404, the positive pressure gas that is not discharged from the exhaust hole 3022 cannot flow back into the airbag 4, and the expansion part 502 is affected by the unexhausted positive pressure gas. The positive-pressure gas out of the exhaust hole 3022 expands due to the pressure; and the positive-pressure gas entering the air hole 201 is finally discharged to the upper surface of the pillow core 2. Due to the flow resistance of the pillowcase 1, part of the positive-pressure gas is directly discharged from the upper side of the air hole 201, and part of the positive-pressure gas flows on the lower surface of the pillowcase 1, and finally discharged from the pillowcase 1 through the fiber gap of the pillowcase 1; until the front end of the movable part 303 is completely attached to the supporting part 302 on the lower side, the movable part 303 no longer moves downward, and the raised part 202 is supported by the bracket 3 and no longer moves downward. The middle part of the pillow core 2 provides support for the user's head, and the raised part 202 provides support for the user's neck. Subsequently, no positive-pressure gas is injected between the expansion part 502 and the supporting part 302, and the expansion part 502 contracts until the positive-pressure gas remaining between the expansion part 502 and the supporting part 302 is completely discharged from the exhaust hole 3022, and the expansion part 502 retracts to fit the lower end surface of the bracket 3.

[0046] See also Figure 8 and Fig. 9 After the user's head leaves the pillow, the protrusion 202 loses the effect of the gravity of the head, and the movable part 303 resets upward under the action of its own elastic force. During the resetting process of the movable part 303, the protrusion 202 is pushed to reset upward. At the same time, the movable part 303 drives the airbag 4 to reset upward. During the resetting process of the airbag 4, the inside of the airbag 4 is in a negative pressure state. At this time, the air inlet check valve 403 is in a connected state, and the air outlet check valve 404 is in a cut-off state. The gas outside the airbag 4 can only enter the airbag 4 through the air inlet 401 and the air inlet check valve 403; until the movable part 303 completely returns to the reset position, the protrusion 202 and the airbag 4 return to the reset position, and at this time, the inside of the airbag 4 is in a full air state at normal pressure.
