[0002] An air source heat pump is a device that uses heat in the air for heating or cooling. It absorbs heat from the outside air for heating in winter and transfers indoor heat to the outdoors in summer, providing a cooling effect.

[0003] Traditional air source heat pumps are installed outdoors without a protective cover design. The air intake holes are prone to water ingress and dust accumulation, which may cause damage to internal components and frequent failures, requiring more frequent cleaning and maintenance to prevent dust clogging and rainwater corrosion. The entry of dust and rainwater will affect the heat exchange efficiency of the heat pump, resulting in increased energy consumption and decreased performance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-5 , an air source heat pump, including a main body 1, a ventilation protection mechanism and a shock absorption mechanism. The ventilation protection mechanism includes a protective cover 2, a support frame 3, a dust-proof net 4, a sealing ring 5 and a rain-proof component. The protective cover 2 is installed at the top and is detachably connected to the main body 1. The support frame 3 is installed inside the protective cover 2 and is fixedly connected to the main body 1. The dust-proof net 4 is installed inside the protective cover 2 and is detachably connected to the main body 1. The sealing ring 5 is fixedly installed at the bottom of the dust-proof net 4 and is fixedly connected to the dust-proof net 4. The rain-proof component includes an extended screw 6, a fastening nut 7, a first rain-proof eaves 8 and a second rain-proof eaves 9. The extended screw 6 is fixedly arranged at the top of the main body 1 and is detachably connected to the protective cover 2. The fastening nut 7 is in threaded engagement with the extended screw 6. The first rain-proof eaves 8 is fixedly installed on the main body 1. The second rain-proof eaves 9 is slidably connected to the main body 1.

[0030] In this embodiment, the ventilation protection mechanism includes a protective cover 2, a support frame 3, a dust-proof net 4, a sealing ring 5 and a rain-proof component. When in use, when the main body 1 operates, a huge suction force is transmitted from the suction hole 18 at the upper end of the main body 1, acting on the dust-proof net 4 through the air inlet hole 19 on the support frame 3, causing the relatively soft dust-proof net 4 to deform. At this time, the dust-proof net 4 is affected by the support frame 3 and thus does not deform. After the suction force passes through the dust-proof net 4, it acts on the air inlet hole 19 on the protective cover 2, thereby sucking in the outside air. During this process, the dust-proof net 4 prevents dust from entering the outside air. And in rainy days, it may suck in rainwater into the protective cover 2. At this time, the sealing ring 5 is installed in the sealing groove 20 on the main body 1 to prevent rainwater from entering the suction hole 18. At the same time, the rainwater falls on the protective cover 2 and then onto the first rain-proof eaves 8. Then, due to the shape of the first rain-proof eaves 8, the rainwater falls. And the second rain-proof eaves 9 fixedly installed on the shock absorption base 13 is very close to the position of the first rain-proof eaves 8, so as to receive the rainwater and block the rainwater outside the shock absorption base 13. When performing maintenance, only need to unscrew the fastening nut 7 that is in threaded engagement with the extended screw 6, and then pick up the protective cover 2, so that the baffle 22 of the protective cover 2 is separated from the main body 1, and the connecting plate 27 fixedly connected to the baffle 22 is separated from the extended screw 6 accordingly. After completing the maintenance of the protective cover 2, then reconnect it according to the above connection method.

[0031] In this embodiment, the shock absorption mechanism includes a sliding chassis 10, a shock pad 11, a shock damper 12, a shock base 13 and an auxiliary mechanism. When in use, when the main body 1 starts to operate, it generates vibrations due to mechanical cooperation. The vibrations are transmitted from the main body 1 to the sliding chassis 10, and then from the sliding base to the connecting rod 14 and the shock pad 11. When the vibrations reach the shock pad 11, the shock pad 11 absorbs part of the energy generated by the vibrations and transmits the remaining energy to the shock damper 12, causing the shock damper 12 installed inside the shock base 13 to absorb the energy generated by the excess vibrations. During this process, due to the extremely small displacement generated by the vibrations of the main body 1, the bump 24 on the sliding chassis 10 starts to slide in the first chute 23 inside the shock base 13.

[0032] In this embodiment, the auxiliary mechanism includes a connecting rod 14, a slider 15, a through rod 16 and a shock spring 17. When in use, when the force generated by the vibrations of the sliding chassis 10 is transmitted to the connecting rod 14, the connecting rod 14 displaces at this time, causing the slider 15 rotatably connected thereto to directly slide in the second chute 26 inside the sliding seat 25. And while the slider 15 is sliding, it transmits the force to the shock spring 17, causing the shock spring 17 to be compressed under the action of the through rod 16. Subsequently, the shock spring 17 rebounds. During this process, the shock spring 17 serves as a carrier for absorbing energy, converting the pressure generated by the vibrations into the frictional force of the slider 15 sliding, thereby assisting the shock damper 12 to reduce the force brought by shock absorption and weakening the vibrations of the main body 1.

[0033] Embodiment 2:

[0034] In summary, during use, when the main body 1 operates, a huge suction force is transmitted from the suction hole 18 at the upper end of the main body 1. Through the air inlet hole 19 on the support frame 3, it acts on the dust-proof net 4, causing the relatively soft dust-proof net 4 to deform. At this time, the dust-proof net 4 is affected by the support frame 3 and thus does not deform. After the suction force passes through the dust-proof net 4, it acts on the air inlet hole 19 on the protective cover 2, thereby sucking in the outside air. During this process, the dust-proof net 4 prevents dust from entering the outside air. It is possible to suck in rainwater into the protective cover 2 on rainy days. At this time, the sealing ring 5 is installed in the sealing groove 20 on the main body 1 to prevent rainwater from entering the suction hole 18. At the same time, the rainwater falls on the protective cover 2 and then onto the first rain shield 8. Subsequently, due to the shape of the first rain shield 8, the rainwater falls. The second rain shield 9 fixedly installed on the shock-absorbing base 13 is very close to the position of the first rain shield 8, thus receiving the rainwater and blocking the rainwater outside the shock-absorbing base 13. During maintenance, only need to unscrew the fastening nut 7 that is threadedly engaged with the extended screw rod 6, and then pick up the protective cover 2, so that the baffle 22 of the protective cover 2 is separated from the main body 1, and the connecting plate 27 fixedly connected to the baffle 22 is separated from the extended screw rod 6 accordingly. After completing the maintenance of the protective cover 2, then reconnect it according to the above connection method. During the operation of the main body 1, due to mechanical cooperation, it generates vibrations. The vibrations are transmitted from the main body 1 to the sliding chassis 10, and then the sliding base transmits them to the connecting rod 14 and the shock-absorbing pad 11. When the vibrations reach the shock-absorbing pad 11, the shock-absorbing pad 11 will absorb a part of the energy generated by the vibrations and transmit the remaining energy to the shock-absorbing damper 12, and cause the shock-absorbing damper 12 installed inside the shock-absorbing base 13 to absorb the energy generated by the excess vibrations. During this process, due to the extremely small displacement generated by the vibrations of the main body 1, the convex block 24 on the sliding chassis 10 starts to slide in the first chute 23 inside the shock-absorbing base 13. When the force generated by the vibration of the sliding chassis 10 is transmitted to the connecting rod 14, at this time the connecting rod 14 undergoes displacement, causing the slider 15 rotatably connected to it to directly slide in the second chute 26 inside the sliding seat 25. And while the slider 15 is sliding, it transmits the force to the shock-absorbing spring 17, causing the shock-absorbing spring 17 to be compressed under the action of the through rod 16. Subsequently, the shock-absorbing spring 17 rebounds. During this process, the shock-absorbing spring 17 serves as a carrier for absorbing energy, converting the pressure generated by the vibrations into the frictional force of the slider 15 sliding, thereby assisting the shock-absorbing damper 12 to reduce the force brought by shock absorption and weakening the vibrations of the main body 1.

For all the cases of fixed connection mentioned above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
