Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a box-type system for cooling and reducing noise of an air pump. Background Art

[0002] Extracorporeal shock wave therapy is a mechanical pulse pressure wave transmitted through a physical mechanism medium (air or gas). It converts the pulse sound waves generated by pneumatics into precise ballistic shock waves. Through the positioning and movement of the treatment probe, it can produce a good therapeutic effect on human tissues with a wide range of pain.

[0003] The extracorporeal shock wave therapy device is equipped with an air pump, which generates the required pneumatic pulse sound waves. Some air pumps on the market use imported silent pumps, which have low noise and a quiet treatment environment, but are expensive, which increases the manufacturing cost of the entire treatment device.

[0004] In order to reduce costs, the air pump uses a plunger pump. The plunger pump is in an oil-free, dry friction state during operation, and is also accompanied by vibration, which will cause high operating temperatures and affect the service life of the plunger pump. The vibration will also generate loud noise, causing noise pollution, affecting the surrounding environment, destroying the quiet treatment environment, and reducing the patient's experience. Summary of the invention

[0005] In order to solve the problems of high temperature and loud noise during the operation of a plunger pump, the utility model provides a box-type system for cooling and reducing the noise of an air pump. Sound-absorbing cotton is used to reduce input and output noise, and an axial flow fan is used to reduce the operating temperature of the plunger pump, thereby controlling the temperature balance.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The axial flow fan is arranged on the rear wall of the box body and at the position corresponding to the pump head of the plunger pump. Direct airflow is adopted to cool down the plunger pump conveniently. The box back cover is arranged at the rear of the box body. The box body and the box back cover are connected through the axial flow fan. A plurality of baffles are arranged alternately on the left and right inside the box back cover. The baffles are arranged below the axial flow fan. Sound-absorbing cotton 1 is also arranged on the surface of the baffle and the inner wall of the box back cover. The lower part of the box back cover is horizontally bent backward to form an air inlet. Sound-absorbing cotton 2 is also arranged in the air inlet. Sound-absorbing cotton 1 and sound-absorbing cotton 2 in the box back cover are convenient for reducing input noise.

[0009] Furthermore, the first and second sound-absorbing cottons are one of pointed-angle sound-absorbing cottons or wavy sponge sound-absorbing cottons. The pointed-angle sound-absorbing cotton is a porous sound-absorbing material made into a conical or wedge-shaped sound-absorbing body to achieve the absorption of incident sound. The wavy sponge sound-absorbing cotton also has a good sound absorption and noise reduction effect.

[0010] Furthermore, the first sound-absorbing cotton is a pointed-angle sound-absorbing cotton, the first sound-absorbing cotton in the box is arranged around the plunger pump, and the second sound-absorbing cotton is a wavy sponge sound-absorbing cotton.

[0012] Furthermore, the axial flow fan and baffles are arranged vertically inside the rear cover of the box, and a plurality of baffles are arranged vertically at intervals inside the rear cover of the box to form an "S"-shaped air inlet channel, which extends the air flow path and facilitates better noise reduction. The upper and lower adjacent baffles are staggered left and right, and the two ends of the air inlet channel are respectively connected to the air inlet and the axial flow fan.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model has a reasonable structural design. Sound-absorbing cotton one and sound-absorbing cotton two are arranged in the rear cover of the box. The air inlet is connected to the axial flow fan through an "S"-shaped air inlet channel. In the process of air entering, the airflow first passes through the wavy sponge sound-absorbing cotton and then passes through the staggered multi-stage pointed-angle sound-absorbing cotton, which can effectively reduce the input noise of the plunger pump and has a significant sound absorption effect.

[0015] The axial flow fan of the utility model corresponds to the pump head of the plunger pump, and the axial flow fan is used to blow air directly to the pump head to achieve cooling, and provide the air required for the operation of the plunger pump.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0021] like Figure 1~Figure 3 As shown, a box-type system for cooling and reducing noise of an air pump is a storage space for the air pump, in which a plunger pump 1 is elastically suspended. The plunger pump 1 is a type of air pump, and the plunger pump 1 is elastically suspended and installed in the box-type system, which can reduce the transmission of vibration when the plunger pump 1 is running. At the same time, the box-type system has the function of cooling and reducing noise, which can ensure the stable and efficient operation of the plunger pump 1 and reduce the operating noise.

[0022] The box system includes a box body 2, a box rear cover 3, an axial flow fan 4 and a baffle 5. The plunger pump 1 is elastically suspended in the box body 2, so that the plunger pump 1 is suspended and installed in the air. The plunger pump 1 elastically contacts the box body 2, which can effectively reduce the vibration of the plunger pump 1 during operation.

[0023] A sound-absorbing cotton 6 is arranged on the inner peripheral side wall of the box body 2, and the sound-absorbing cotton 6 in the box body 2 is arranged around the plunger pump 1. The sound-absorbing cotton 6 is a kind of sharp-angle sound-absorbing cotton or a wave-shaped sponge sound-absorbing cotton. Here, the sound-absorbing cotton 6 adopts a sharp-angle sound-absorbing cotton, which can effectively absorb the noise of the plunger pump 1 when it is running.

[0024] The bottom of the box body 2 is connected to an air outlet base 7, that is, the bottom side wall of the box body 2 is hollowed out, and the air inside the box body 2 can flow out from the hollow position and flow into the air outlet base 7. The air outlet base 7 is a rectangular flat tube structure, the middle of the air outlet base 7 is open and connected to the box body 2 upward, and the two ends of the air outlet base 7 extend horizontally outward and protrude from the box body 2, that is, the length of the air outlet base 7 is greater than the width of the box body 2.

[0025] The two ends of the air outlet base 7 are air outlets 8, and the internal space of the air outlet base 7 is a double-sided air outlet channel 9. The air flowing into the air outlet base 7 from the box body 2 passes through the double-sided air outlet channel 9 and can flow back to the air outlets 8 at both ends.

[0026] A sound-absorbing cotton 2 10 is arranged in the air outlet 8 to process the noise of the outflowing air. Here, the sound-absorbing cotton 2 10 is a kind of pointed sound-absorbing cotton or wavy sponge sound-absorbing cotton. Specifically, the sound-absorbing cotton 2 10 is a wavy sponge sound-absorbing cotton. Wavy sponge sound-absorbing cotton is arranged in the upper and lower side walls of the air outlet 8. The wavy sponge sound-absorbing cottons in the upper and lower positions are arranged opposite to each other and overlapped, which can better reduce the output noise.

[0027] An axial flow fan 4 is arranged on the rear wall of the box body 2, corresponding to the pump head position of the plunger pump 1, and air can be supplied to the plunger pump 1 through the axial flow fan 4 to meet its operation requirements and cool it by direct blowing of airflow. A box rear cover 3 is arranged behind the box body 2, and the box rear cover 3 covers the axial flow fan 4, and the box body 2 and the box rear cover 3 are connected through the axial flow fan 4.

[0028] In order to realize the air intake of the axial flow fan 4, the lower part of the box rear cover 3 is bent backward and horizontally to form an air inlet 11. External air can enter the box rear cover 3 through the air inlet 11, and then enter the inside of the box body 2 as the axial flow fan 4 runs.

[0029] In order to achieve noise reduction when the axial flow fan 4 takes in air, a plurality of baffles 5 are staggered left and right inside the box rear cover 3. Specifically, the plurality of baffles 5 are arranged in intervals up and down inside the box rear cover 3, and the upper and lower adjacent baffles 5 are staggered left and right, thereby forming an "S"-shaped air inlet channel 12 between the plurality of baffles 5, and the two ends of the air inlet channel 12 are respectively connected to the air inlet 11 and the axial flow fan 4, which can extend the air flow path.

[0030] After the baffle 5 is installed, it is arranged below the axial flow fan 4, that is, the axial flow fan 4 and the baffle 5 are arranged up and down in the box back cover 3. The surface of the baffle 5 and the inner wall of the box back cover 3 are also provided with sound-absorbing cotton 16. The sound-absorbing cotton 16 can be selected from the above, and two types can be selected. The sound-absorbing cotton 16 here still uses the sharp-angle sound-absorbing cotton. At the same time, the air inlet 11 is also provided with sound-absorbing cotton 2 10. The sound-absorbing cotton 2 10 can be selected from the above, and two types can be selected. The sound-absorbing cotton 2 10 here still uses the corrugated sponge sound-absorbing cotton, thereby reducing the input noise.

[0031] The principle of the utility model is that when the plunger pump 1 is running, the axial flow fan 4 is running at the same time, and the external air flows to the position of the axial flow fan 4 after passing through the air inlet 11 and the "S"-shaped air inlet channel 12 in sequence. During the air flow process, the input noise can be reduced under the action of the multi-stage sound-absorbing cotton 1 6 and the sound-absorbing cotton 2 10. The axial flow fan 4 blows air into the box body 2, forming a direct air blow to the pump head of the plunger pump 1, which can cool the pump head of the plunger pump 1, and the air in the box body 2 is also required for the operation of the plunger pump 1.

[0032] The noise generated by the operation of the plunger pump 1 is absorbed by the sound-absorbing cotton 16 in the box 2. At the same time, the air in the box 2 flows out to the air outlet base 7. Under the action of the double-sided air outlet channels 9, the airflow flows in the opposite direction and flows out from the air outlet 8. The output noise is reduced by the sound-absorbing cotton 10 in the air outlet 8. In this way, the plunger pump 1 can be cooled down during operation, and the input and output noises can be effectively processed, the noise can be better reduced, the sound absorption effect is obvious, the noise reduction of the plunger pump 1 is guaranteed, the quiet treatment environment is guaranteed, and the patient's good experience is guaranteed.

Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
