Description

Air pump assembly, controller and bed Technical Field

[0001] The present invention relates to the field of bedding, and in particular to an air pump component, a controller and a bed. Background Art

[0002] An existing bed includes a bed frame and a mattress mounted on the bed frame. The mattress is equipped with a controller and an airbag. The controller is equipped with an air pump assembly and a solenoid valve assembly. The high-pressure airflow generated by the air pump assembly is transmitted to the airbag under the guidance of the solenoid valve assembly. The mattress hardness is adjusted by adjusting the air pressure in the airbag. The existing air pump assembly includes a pump housing and a pump body mounted within the pump housing. The pump body is in direct contact with the pump housing. The vibration generated by the operation of the pump body is directly transmitted outward through the pump housing, causing the controller to vibrate during use and generating noise due to the vibration, affecting the user's sleep and user experience. In addition, the pump body includes a gas pumping unit and a motor that drives the gas pumping unit. Because the motor is heavier than the gas pumping unit, the gas pumping unit generates relatively large vibrations when the motor is in operation. The vibration is transmitted outward through the pump housing, resulting in increased noise and affecting the user experience. Summary of the Invention

[0003] In order to address the deficiencies of the prior art, the present invention provides an air pump assembly, a controller, and a bed, which reduce vibration and noise by arranging soft vibration damping parts between the pump body and the pump housing, thereby reducing the impact on the user's sleep and improving the user experience.

[0004] The present invention is implemented as follows: an air pump assembly comprising a pump housing with an internal assembly cavity and a pump body disposed within the assembly cavity. The pump body is characterized in that a vibration damping assembly is provided on the pump body to reduce vibration and noise generated during operation. The vibration damping assembly on the pump body reduces noise by reducing vibration generated during operation, effectively minimizing the impact of noise and vibration on the user's sleep and enhancing the user experience.

[0005] Preferably, the vibration damping assembly includes a soft vibration damper, and the pump body is suspended in the assembly cavity through the soft vibration damper, and the soft vibration damper offsets the vibration generated by the pump body during operation through its own deformation. A soft vibration damper is provided between the pump body and the pump casing, and the soft vibration damper has a deformation reset performance. The soft vibration damper can offset the vibration generated by the pump body during operation by utilizing its own deformation, thereby preventing the pump casing from generating noise due to receiving vibration from the pump body, effectively reducing the impact of noise and vibration on the user's sleep, and can also guide the pump body to reset by resetting the deformation when the vibration of the pump body disappears, thereby supporting and positioning the pump body, ensuring that the pump body is suspended in the pump casing and will never come into direct contact with the pump body, thereby avoiding the vibration generated by the pump body from being directly transmitted to the pump casing, and improving the user experience.

[0006] Preferably, the soft vibration damper comprises a first connection portion connected to the pump casing, a second connection portion sleeved on the pump body, and a vibration damper portion disposed between the first and second connection portions. The first and second connection portions are connected to the pump casing and the pump body, respectively, ensuring that the vibration damper portion can effectively receive vibrations from the pump body and offset them through its own deformation. Furthermore, the vibration damper portion acts as a position limiter for the pump body, preventing the pump body from directly contacting the pump casing due to excessive displacement, thereby effectively enhancing the vibration damping effect of the vibration damper portion.

[0007] Preferably, the first connecting portion is a collar, and a screw is provided on the inner wall of the assembly cavity. The screw passes through the collar and is fixed to the inner wall of the assembly cavity at its end, thereby fixing the first connecting portion to the pump housing. The collar is placed on the screw, and the screw is connected to the pump housing, ensuring that the relative position between the first connecting portion and the pump housing is fixed.

[0008] Preferably, there are four screws and they are arranged in parallel with each other in the assembly cavity. The soft vibration damper includes four collars that can be respectively placed on the corresponding screws so that the pump body is tightened and suspended in the assembly cavity. The vibration damping part includes a transverse vibration damping plate spanning the collars and an oblique vibration damping plate spanning the transverse vibration damping plate and the second connecting part. The soft vibration damper is connected to the corresponding screws through the collars, so that the soft vibration damper is tightened and positioned in four directions by the four sets, which ensures that the pump body can be suspended in the assembly cavity and prevents direct contact between the pump body and the pump casing. The vibration damping part can also be used to absorb vibrations and prevent vibrations from being transmitted outward. The vibration damping part includes a transverse vibration damping plate and an oblique vibration damping plate. The vibration generated by the pump body will be transmitted to the transverse vibration damping plate through the oblique vibration damping plate, thereby improving the vibration damping effect by increasing the transmission distance of the vibration on the vibration damping part.

[0009] Preferably, the pump housing includes a kit and a cover. A cylindrical assembly groove is provided in the kit. The cover covers the notch of the assembly groove and is enclosed with the kit to form the assembly cavity. The wall of the assembly groove away from the notch is provided with a screw hole. The cover is provided with a through hole. The screw passes through the through hole and the collar and is screwed and locked with the corresponding screw hole. The assembly groove is cylindrical, so that the cross-sectional profiles of the assembly groove are the same, which is convenient for processing and production, as well as for the installation of the pump body and the soft vibration damping component. The axes of the screw and the kit are arranged parallel to each other. The screw passes through the through hole from the outside to the inside and is screwed and locked with the corresponding screw hole, so that the screw is fixed in the assembly cavity and is positioned by the collar, ensuring that the pump body is tightened and positioned by the soft vibration damping component.

[0010] Preferably, a retaining ring is provided at the end of the screw exposed from the cover, and a sealing ring is sleeved on the section of the screw located between the retaining ring and the cover. Once installed, the retaining ring and the cover tightly clamp the sealing ring to seal the perforation. The retaining ring acts as a limiter for the cover, preventing it from detaching from the assembly. The sealing ring is sleeved on the screw and clamped and fixed by the retaining ring and the cover, effectively sealing the gap between the perforation and the screw, ensuring that external airflow enters the assembly chamber along a predetermined path and is drawn out by the pump body, while also effectively eliminating noise generated by direct contact and friction between the screw and the cover.

[0011] Preferably, the soft vibration damping components are two components, including a main component and a secondary component, which are fixed to the two ends of the pump body to prevent contact and collision between the pump body and the pump casing. The main component and the secondary component are respectively arranged at both ends of the pump body. This not only ensures that the pump body is suspended in the assembly cavity in a predetermined posture, but also disperses and offsets vibrations by adding the soft vibration damping components, thereby improving the vibration reduction effect.

[0012] Preferably, the second connecting part of the main component is a main sleeve, the inner diameter of the main sleeve matches the diameter of the pump body, the main sleeve extends radially inward away from the side port of the auxiliary component to form a positioning ring, the pump body is inserted into the main sleeve and contacts the positioning ring, so that the pump body is positioned by the main sleeve. The main component is tightly sleeved on the pump body through the main sleeve. The main component is sleeved on the pump body through the main sleeve, which not only supports and positions the pump body, but also uses its own deformation to offset the vibration from the pump body and prevent the vibration from being transmitted to the pump casing. The main sleeve is tightly sleeved on the end of the pump body, which plays a radial limiting role on the pump body. The limiting ring contacts the end face of the pump body and plays an axial limiting role on the pump body, thereby ensuring that the end of the pump body is accurately positioned in the pump casing under the action of the main sleeve.

[0013] Preferably, an air outlet is provided in the middle of the end surface of the pump body, and the second connecting portion of the auxiliary component is a secondary sleeve, the inner diameter of which matches the diameter of the air outlet, and the auxiliary component is tightly mounted on the air outlet via the secondary sleeve. The auxiliary component, mounted on the air outlet via the secondary sleeve, not only supports and positions the pump body but also offsets vibration from the pump body through its own deformation, preventing vibration from being transmitted to the pump casing.

[0014] Preferably, a motor is provided in the front end of the pump body, and a gas pumping unit is provided in the rear end. The vibration reduction assembly includes a counterweight, which is provided on the gas pumping unit to reduce the amplitude of the gas pumping unit during operation. Providing the counterweight on the gas pumping unit ensures weight balance between the two ends of the pump body by reducing the weight difference between the gas pumping unit and the motor, effectively reducing the vibration amplitude of the gas pumping unit during operation, thereby effectively reducing the noise generated by the operation of the air pump assembly, preventing the pump housing from generating noise due to receiving vibrations from the pump body, effectively reducing the impact of noise and vibration on the user's sleep, and improving the user experience.

[0015] Preferably, the counterweight is sleeve-shaped and is sleeved and fixedly attached to the rear end of the pump body. The counterweight is sleeved and fixedly attached to the gas pumping unit, eliminating the gap between the counterweight and the gas pumping unit to ensure synchronous movement of the two. The counterweight can use its own weight to offset some vibrations, effectively reducing the vibration amplitude of the gas pumping unit.

[0016] Preferably, the thickness of the counterweight is A, 1mm≤A≤5mm, which not only ensures that the counterweight has a larger weight and ensures that the weight is balanced between the front and rear ends of the pump body, but also facilitates assembly by limiting the thickness of the counterweight and reduces the size requirements for the space inside the pump casing.

[0017] Preferably, the counterweight is fixed to the rear end of the pump body by gluing, and the relative positions between the counterweight and the rear end of the pump body are fixed, which can not only prevent the counterweight from detaching from the rear end of the pump body, but also ensure that the counterweight can apply a constant force to the rear end of the pump body, ensuring that the vibration amplitude of the rear end of the pump body is always within a preset range.

[0018] Preferably, the axial dimension of the counterweight is not larger than the axial dimension of the gas pumping part, and the counterweight completely covers the outer wall of the gas pumping part. The thickness of the counterweight is reduced by increasing the area covered on the surface of the gas pumping part, thereby increasing the weight of the counterweight without excessively increasing the occupied space.

[0019] Preferably, the counterweight is made of butyl rubber, which has a high density, effectively reducing the thickness of the counterweight, and has good elastic deformation performance, so that the counterweight can be tightly positioned on the rear end of the pump body using its own elasticity, and can prevent the counterweight from resonating under the vibration of the pump body, thereby ensuring vibration reduction reliability.

[0020] A controller using the air pump assembly includes a housing with an internal mounting cavity, and a solenoid valve assembly, an air pump assembly, and a circuit board disposed within the mounting cavity. The air pump assembly is characterized in that a vibration damping assembly is provided on the air pump assembly to reduce vibration and noise generated by the operation of the air pump assembly. The air pump assembly and solenoid valve assembly are suspended on a suspension frame via a vibration damping strap, and the suspension frame is overlapped on the bottom wall of the mounting cavity via a silicone foot pad. The air pump assembly includes a gas pumping portion with a counterweight mounted thereon. The vibration damping strap, soft vibration damping member, and counterweight are utilized to reduce vibration and noise, preventing the noise generated by the operation of the air pump assembly from affecting the user's sleep.

[0021] A bed using the controller includes a cushion body, the cushion body including a comfort layer, an adjustment layer, and a spring layer arranged sequentially from top to bottom. The adjustment layer includes a front sponge section, a middle adjustment section, and a rear sponge section arranged sequentially from front to back. The middle adjustment section is provided with an airbag with adjustable hardness and softness. The rear sponge section is provided with a controller for controlling the hardness of the airbag, and the controller is connected to the airbag via an air pipe. Placing the controller within the cushion body effectively shortens the distance between the controller and the middle adjustment section, facilitating piping layout. A multi-stage vibration damping structure is provided to prevent vibrations generated by the operation of the air pump assembly and the solenoid valve assembly from being transmitted through the outer casing to the cushion body, ensuring a better sleeping experience for the user.

[0022] The beneficial effects of the present invention are as follows: a soft vibration damper is arranged between the pump body and the pump casing. The soft vibration damper has a deformation reset performance. The soft vibration damper can offset the vibration generated by the pump body during operation by utilizing its own deformation, thereby preventing the pump casing from generating noise due to receiving the vibration from the pump body, effectively reducing the impact of noise and vibration on the user's sleep, and can also guide the pump body to reset by resetting the deformation when the vibration of the pump body disappears, thereby supporting and positioning the pump body, ensuring that the pump body is suspended in the pump casing and will never come into direct contact with the pump body, thereby avoiding the vibration generated by the pump body from being directly transmitted to the pump casing, and improving the user experience.

[0035] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0036] Example 1:

[0037] This embodiment provides an air pump assembly.

[0038] The air pump assembly shown in Figure 1 consists of a pump housing with an internal assembly cavity and a pump body disposed within the cavity. The pump body is equipped with a vibration damping assembly to reduce vibration and noise generated during operation. The vibration damping assembly reduces noise by dampening the vibration generated by the pump body during operation, effectively minimizing the impact of noise and vibration on the user's sleep and enhancing the user experience.

[0039] In this embodiment, the vibration damping assembly includes a soft vibration damper, and the pump body is suspended within the assembly cavity via the soft vibration damper. The soft vibration damper offsets the vibration generated by the pump body during operation through its own deformation. The soft vibration damper includes a first connection portion connected to the pump housing, a second connection portion sleeved on the pump body 1, and a vibration damper portion disposed between the first connection portion and the second connection portion. The soft vibration damper is fixedly connected to the pump housing and the pump body 1 respectively via the first connection portion and the second connection portion, and the vibration generated by the operation of the pump body 1 is offset by the deformation reset of the vibration damper portion, thereby improving the sleeping experience by reducing vibration and noise.

[0040] In this embodiment, two soft vibration dampers are provided (as shown in Figure 2), comprising a main component 12 and a secondary component 13. These components are respectively fixedly attached to the respective ends of the pump body 1 to prevent contact and collision between the pump body 1 and the pump casing. The main component 12 and secondary component 13 are respectively sleeved onto the respective ends of the pump body 1, allowing the pump body 1 axis to maintain a parallel position with the axis of the pump casing. This ensures that the pump body 1 is suspended within the assembly cavity and does not contact the pump casing, preventing vibrations generated by the pump body 1 from being directly transmitted to the pump casing.

[0041] In this embodiment, the pump housing includes a sleeve 6 and a cover 7 (as shown in FIG3 ). The sleeve 6 is provided with a cylindrical assembly groove. The cover 7 covers the notch of the assembly groove and encloses the sleeve 6 to form the assembly cavity. The wall of the assembly groove away from the notch is provided with a screw hole 8. The cover 7 is provided with a through-hole 9. The screw 3 passes through the through-hole 9 and the collar 2 and is screwed and locked with the corresponding screw hole 8. During installation, first, the auxiliary component 13 is placed on the air outlet 15 of the pump body 1 through the auxiliary sleeve 16, and the main component 12 is placed on the end of the pump body 1 away from the air outlet 15 through the main sleeve 14. Then, the end of the screw 3 passes through the sealing ring 11, the through-hole 9, and the corresponding collar 2 in sequence, so that the pump body 1, the soft vibration damper, the screw 3, and the cover 7 are assembled and connected. Finally, the cover 7 is placed on the notch of the assembly groove and screwed and locked with the end of the screw 3 through the corresponding screw hole 8.

[0042] After installation, the screw 3 is locked with the corresponding screw hole 8. The screw 3 is restricted by the limiting ring 10 to limit the movement of the cover 7, so that the cover 7 is tightly covered on the sleeve 6, ensuring that the sealing ring 11 is sealed and clamped and effectively blocks the gap between the through hole 9 and the screw 3; the screw 3 is supported and limited by the screw hole 8 and the through hole 9, and plays a positioning role for the collar 2, ensuring that the soft vibration damper is tightened by the collar 2 and ensuring that the pump body 1 is suspended in the assembly cavity. When in use, the pump body 1 does not contact the pump casing. The vibration generated by the operation of the pump body 1 will be transmitted to the main part 12 and the auxiliary part 13 respectively. The vibration damping parts on the main part 12 and the auxiliary part 13 are used to offset the deformation, thereby playing a role in reducing vibration and noise.

[0043] In this embodiment, a retaining ring 10 is provided at the end of the screw 3 exposed from the cover 7. A sealing ring 11 is sleeved on the section of the screw 3 between the retaining ring 10 and the cover 7. Once installed, the retaining ring 10 and the cover 7 tightly clamp the sealing ring 11 to seal the through-hole 9. The inner diameter of the sealing ring 11 is between the outer diameter of the retaining ring 10 and the diameter of the screw 3. This ensures that the sealing ring 11 can be sleeved on the screw 3 and that it can be squeezed and retained by the retaining ring 10 to form an annular contact surface, thereby ensuring sealing reliability.

[0044] In this embodiment, the first connection portion is a collar 2. A screw 3 is provided on the inner wall of the assembly cavity. The screw 3 passes through the collar 2 and is fixed to the inner wall of the assembly cavity at its end, thereby fixing the first connection portion to the pump casing. The first connection portions on both the main component 12 and the auxiliary component 13 are collars 2. The ends of the screw 3 are connected to the cover 7 and the screw hole 8, respectively, and the middle section passes through the collar 2. The collar 2 is placed on the screw 3, ensuring that the pump body 1 can be tightened and positioned by the soft vibration damping component, thereby ensuring that the vibration damping component can offset vibration through its own deformation, preventing vibration from the pump body 1 from being transmitted outward through the soft vibration damping component.

[0045] In this embodiment, there are four screw rods 3 and they are arranged parallel to each other in the assembly cavity. The soft vibration damper includes four collars 2 that can be respectively placed on the corresponding screw rods 3. The collars 2 are dispersed so that the collars 2 can provide pulling forces in four different directions to the soft vibration damper, ensuring that the soft vibration damper is effectively tightened and can cope with vibrations in all directions of the pump body 1. Since the axes of the screw rod 3 and the assembly groove are arranged parallel to each other, the soft vibration damper is arranged perpendicular to the screw rod 3. When the screw rod 3 and the collar 2 are connected in place and tightened and positioned, the pulling force between the inner wall of the collar 2 and the outer wall of the screw rod 3 can generate friction, ensuring that the collar 2 will not slide along the axial direction of the screw rod 3, thereby ensuring that the pump body 1 is reliably positioned along the axial direction of the screw 3, and preventing the pump body 1 from contacting the end face of the assembly cavity.

[0046] In this embodiment, the vibration damping portion includes a horizontal vibration damping plate 4 spanning between the collars 2 and an inclined vibration damping plate 5 spanning between the horizontal vibration damping plate 4 and the second connecting portion. The collars 2 are four and arranged separately, including a No. 1 ring and a No. 2 ring located at the top and on both sides of the assembly cavity, and a No. 3 ring and a No. 4 ring located at the bottom and on both sides of the assembly cavity. The No. 1 and No. 3 rings, and the No. 2 and No. 4 rings are vertically aligned. The vibration damping portion includes two horizontal vibration damping plates 4 and two inclined vibration damping plates 5. A horizontally arranged horizontal vibration damping plate 4 spans between the No. 1 and No. 2 rings, and between the No. 3 and No. 4 rings. Two inclined vibration damping plates 5 are fixedly connected to the second connecting portion in the middle section of each horizontal vibration damping plate 4. The inclined vibration damping plates 5 and the horizontal vibration damping plates 4 are used to provide multi-stage vibration damping of the vibration from the pump body 1, effectively improving the vibration damping effect.

[0047] In this embodiment, the second connecting portion of the main component 12 is a main sleeve 14 (as shown in Figure 4), the inner diameter of the main sleeve 14 matches the diameter of the pump body 1, and the main sleeve extends radially inward away from the side port of the auxiliary component 13 to form a positioning ring 28. The pump body 1 is inserted into the main sleeve 14 and contacts the positioning ring 28 so that the pump body 1 is positioned by the main sleeve 14. The middle part of the end face of the pump body 1 is provided with an air outlet 15, and the second connecting portion of the auxiliary component 13 is a auxiliary sleeve 16 (as shown in Figure 5), the inner diameter of the auxiliary sleeve 16 matches the diameter of the air outlet 15, and the auxiliary component 13 is tightly sleeved on the air outlet 15 through the auxiliary sleeve 16. The inner wall of the main sleeve 14 and the outer wall of the pump body 1, as well as the inner wall of the auxiliary sleeve 16 and the outer wall of the air outlet 15, fit tightly together, not only radially positioning the pump body 1 and improving positioning reliability, but also effectively transmitting the vibration generated by the pump body 1 to the vibration-damping portions of the main component 12 and the auxiliary component 13. The coordinated use of the main component 12 and the auxiliary component 13 enhances the vibration-damping effect. Furthermore, the positioning ring 28 contacts the end surface of one end of the pump body 1, while the auxiliary sleeve 16 contacts the end surface of the other end of the pump body 1, thus providing axial positioning for the pump body 1 and preventing the pump body 1 from colliding with the pump casing due to axial deviation.

[0048] In this embodiment, the main component 12 and the auxiliary component 13 are both integrally formed structures, and are preferably made of materials with good deformation restoration properties such as rubber and silicone.

[0049] It can be understood that a sleeve is provided on the section of the screw 3 between the collars 2, and the end faces of the sleeve respectively contact the corresponding collars 2, which plays an axial limiting role on the collars 2 on the same screw 3, and should also be regarded as a specific implementation method of this embodiment.

[0050] Example 2:

[0051] Compared to the first embodiment, this embodiment provides another air pump assembly.

[0052] The air pump assembly shown in Figures 6 and 7 consists of a pump housing 29 with an internal assembly cavity and a pump body 1 disposed within the assembly cavity. The pump body 1 is fixedly connected to the pump housing 29 via a soft vibration damping member. A motor 30 is disposed within the front end of the pump body 1, and a gas pumping unit 31 is disposed within the rear end. A counterweight 32 is disposed on the gas pumping unit 31 to reduce the amplitude of the gas pumping unit 31 during operation. The gas pumping unit 31 reduces the weight difference between the motor 30 and the gas pumping unit 31 by providing the counterweight 32, so that the front and rear ends of the pump body 1 have a balanced weight, effectively preventing the gas pumping unit 31 from vibrating significantly due to its light weight. By suppressing the vibration amplitude, the noise generated by the vibration is reduced, thereby reducing the impact of vibration and noise on the user's sleep and ensuring a good user experience.

[0053] In this embodiment, the pump body 1 is formed by a fixed assembly of a motor 30 and a gas pumping unit 31 (as shown in FIG9 ). The motor 30 drives the gas pumping unit 31 to operate, compress, and transport gas, ensuring that the pump body 1 can deliver high-pressure airflow. The gas pumping unit 31 is equipped with a moving part driven by the motor 30. The moving part generates vibrations during operation. The weight difference between the motor 30 and the gas pumping unit 31 reduces the vibration amplitude of the gas pumping unit 31 during operation, thereby effectively reducing the vibration transmitted from the pump body 1. By reducing the vibration of the pump housing 29, the noise generated by the operation of the pump body 1 is reduced, ensuring a better sleep experience for the user.

[0054] In this embodiment, the counterweight 32 is sleeve-shaped (as shown in FIG8 ) and is mounted and fixedly attached to the rear end of the pump body 1. The gas pumping section 31 is cylindrical in structure, with the axes of the gas pumping section 31 and the motor 30 oriented in the same direction, so that the motor 30 and the gas pumping section 31 are located at opposite ends of the pump body 1. The outer wall of the gas pumping section 31 is annular, and the counterweight 32 can be mounted and fixedly attached to the outer wall of the gas pumping section 31, ensuring that the counterweight 32 and the gas pumping section 31 are synchronized and linked, and the weight of the counterweight 32 offsets the kinetic energy of the vibration, thereby reducing the vibration amplitude. Due to the principle of conservation of kinetic energy, the heavier the driven object, the lower the speed it can achieve, and thus the smaller the distance it can move while maintaining constant losses. By providing the counterweight 32, the weight of the gas pumping section 31 is increased, effectively reducing the vibration amplitude of the gas pumping section 31.

[0055] In this embodiment, the inner wall profile of the counterweight 32 matches the outer wall profile of the gas pumping portion 31. The counterweight 32 fits snugly over the gas pumping portion 31, ensuring a secure connection between the two and preventing vibrational detachment. The counterweight 32 is adhesively bonded to the rear end of the pump body 1. The inner wall of the counterweight 32 and the outer wall of the rear end of the pump body 1 are adhered to each other with glue, effectively improving the reliability of the connection between the counterweight 32 and the pump body 1.

[0056] In this embodiment, the axial dimension of the counterweight 32 is no greater than the axial dimension of the gas pumping portion 31, so that the counterweight 32 can completely cover the outer wall of the gas pumping portion 31. The circumferential sections of the counterweight 32 have the same thickness, so that the weight of the counterweight 32 can be evenly distributed on the periphery of the outer wall of the gas pumping portion 31, preventing the gas pumping portion 31 from vibrating in a biased manner due to excessive local weight. The thickness of the counterweight 32 is A, where A = mm. This ensures that the counterweight 32 has a large weight and a balanced weight between the front and rear ends of the pump body 1. It also facilitates assembly by limiting the thickness of the counterweight 32, reducing the size requirements for the space within the pump housing 29.

[0057] In this embodiment, the counterweight 32 is made of butyl rubber, which is easy to process and has low cost. It also prevents resonance between the counterweight 32 and the pump body 1, ensuring that the pump body 1 operates smoothly within a preset vibration amplitude. In addition, the counterweight 32 can also be made of silicone, rubber, etc., which should be considered as specific implementations of this embodiment.

[0058] It is understandable that the parameter A can also be 1mm, 3mm, 4mm, 5mm, etc., as long as it meets the requirement of 1mm≤A≤5mm.

[0059] It can be understood that the air pump assembly can selectively use the counterweight 32 and the soft vibration damping component or use them together, and both should be regarded as specific embodiments of the present invention.

[0060] The other structures and effects of the air pump assembly described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0061] Example 3:

[0062] Compared with the first or second embodiment, this embodiment provides a controller.

[0063] The controller shown in Figure 10 is composed of a shell with an internal mounting cavity, and a solenoid valve assembly 17, an air pump assembly 27 and a circuit board arranged in the mounting cavity. The air pump assembly 27 is provided with a vibration reduction assembly to reduce the vibration and noise generated by the operation of the air pump assembly 27.

[0064] In this embodiment, the vibration damping assembly includes a vibration damping belt 18. The air pump assembly 27 and the solenoid valve assembly 17 are suspended on a suspension 19 via the vibration damping belt 18. The suspension 19 is attached to the bottom wall of the mounting cavity via a silicone foot pad 20. A circuit board controls the operation of the solenoid valve assembly 17 and the air pump assembly 27. The high-pressure airflow generated by the air pump assembly 27 is guided by the solenoid valve assembly 17 and delivered to the target space, thereby adjusting the air pressure within the target space.

[0065] In this embodiment, the target space can be an airbag, so that the air pump assembly can inflate the airbag, or it can be an external space, so that the air pump assembly can exhaust the airbag.

[0066] In this embodiment, the air pump assembly 27 and the solenoid valve assembly 17 are suspended on the suspension 19 through a vibration-damping belt 18, and the suspension 19 is overlapped on the bottom wall of the installation cavity through a silicone foot pad 20, so that the vibration generated by the operation of the air pump assembly 27 and the solenoid valve assembly 17 will be offset by the deformation of the vibration-damping belt 18 and the silicone foot pad 20 in turn, and the vibration of the shell is reduced through multi-stage vibration reduction, thereby reducing the noise during the operation of the controller 26 and reducing the impact on the user's sleep.

[0067] In this embodiment, the controller 26 is equipped with a piping assembly comprising a noise reduction box, an internal tube spanning the air pump assembly 27 and the solenoid valve assembly 17, and an external tube connecting the solenoid valve assembly 17 to the external target space. The internal tube is completely concealed within the housing, while multiple external tubes are provided to connect to different target spaces. The high-pressure airflow generated by the air pump assembly 27 is transmitted through the internal tube to the solenoid valve assembly 17. The solenoid valve assembly 17, through opening and closing control, directs the high-pressure airflow toward the airbag forming the target space, thereby enabling adjustable airbag firmness.

[0068] The other structures and effects of the air pump assembly described in this embodiment are consistent with those of the first or second embodiment and will not be described in detail.

[0069] Example 4:

[0070] Compared with the third embodiment, this embodiment provides a bed.

[0071] The bed shown in Figure 11 is composed of a cushion body, which includes a comfort layer 21, an adjustment layer and a spring layer 22 arranged in sequence from top to bottom. The adjustment layer includes a front sponge segment 23, a middle adjustment segment 24 and a rear sponge segment 25 arranged in sequence from front to back. The middle adjustment segment 24 is provided with an airbag with adjustable hardness, and the rear sponge segment 25 is provided with a controller 26 for controlling the hardness of the airbag. The controller 26 is connected to the airbag through an trachea.

[0072] In this embodiment, the cushion body includes an outer cover that integrally encloses the comfort layer 21, the adjustment layer, and the spring layer 22. The comfort layer 21 conforms closely to the user's surface, increasing the contact area and enhancing support comfort. The adjustment layer adjusts the hardness of the cushion body by controlling the air pressure within the airbags, making the hardness adjustable to meet the user's varying needs. The spring layer 22 provides overall support for the user. The outer cover protects the cushion body and facilitates disassembly and cleaning.

[0073] In this embodiment, the controller 26 is disposed inside the cushion body, which effectively shortens the distance between the controller 26 and the airbag and facilitates pipeline laying.

[0074] The other structures and effects of the controller 26 described in this embodiment are consistent with those in the third embodiment and will not be described in detail.
