Description

Technical Field

[0001] The present invention relates to the field of cleaning machines, in particular to an air pump structure arrangement and a cleaning machine provided with the air pump structure. Background Art

[0002] A washing machine is a small kitchen appliance primarily used to clean and disinfect food or kitchenware. Examples include fruit and vegetable washers, dishwashers, and sinks. To ensure the cleanliness of fruits and vegetables, existing washing machines typically incorporate an air pump. This pump pumps air into the water inside the washing machine via a pipe, achieving the desired cleaning effect.

[0003] The air pump is installed inside the cleaning machine. During operation, it draws in air from the external environment and compresses it, generating air pressure. The operation of the air pump generates a certain degree of vibration. If the air pump is installed directly inside the fruit and vegetable machine, it will collide with the inner wall or other components of the machine, thereby generating noise. Most existing fruit and vegetable machines do not have a corresponding vibration reduction structure, or simply install a shock-absorbing pad on the bottom surface of the air pump installation, which has an unsatisfactory vibration reduction effect. In addition, the internal and external environment of the cleaning machine is relatively humid. The air pump and the shock-absorbing pad are directly exposed to the environment, which makes them prone to rust and corrosion, shortening their service life. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an air pump assembly and a cleaning machine, wherein a shell is provided to provide a reasonable installation environment for the air pump; and a corresponding vibration reduction structure is added to the air pump to achieve the effect of reducing noise.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an air pump assembly, including an air pump and a shell, a sealing ring is provided at the upper end of the air pump, and the air pump is installed in the shell through the sealing ring.

[0006] A further preferred embodiment of the present invention is as follows: the sealing ring comprises an upper gasket and a lower gasket, the upper gasket is located on the top surface of the air pump, and the lower gasket is wrapped around the outer circumference of the air pump.

[0007] A further preferred solution of the present invention is that a connecting piece extends outward from the bottom surface of the upper gasket, the connecting piece is wrapped around the top surface of the air pump, and the outer periphery of the connecting piece is connected to the top surface of the lower gasket.

[0008] A further preferred embodiment of the present invention is as follows: a plurality of tubular members are erected on the connecting piece, and the plurality of tubular members are evenly distributed around the outer circumference of the upper gasket.

[0009] A further preferred solution of the present invention is that connecting edges extend from both sides of the tubular member to be connected to the outer wall of the upper gasket.

[0010] A further preferred embodiment of the present invention is that the top surface of the sealing ring is in contact with the housing. Specifically, the top surface of the upper gasket is in contact with the housing.

[0011] A further preferred embodiment of the present invention is that the outer wall of the sealing ring is in contact with the housing. Specifically, the outer wall of the lower gasket is in contact with the inner wall of the housing.

[0012] A further preferred solution of the present invention is that a circle of undercuts is provided at the bottom of the sealing ring, and the undercuts are snapped into the air pump.

[0013] A further preferred solution of the present invention is that the connecting piece is a ring piece structure and its inner ring is higher than the outer ring, and a circle of gaskets is provided on the bottom surface of the connecting piece, and the inner side of the gasket is embedded in the top surface of the air pump.

[0014] A further preferred solution of the present invention is that the top surface of the tubular member is flush with the top surface of the upper gasket, and the top surface of the tubular member is in contact with and connected to the shell.

[0015] A further preferred solution of the present invention is that the top surface of the connecting edge is flush with the top surface of the upper gasket, and the top surface of the connecting edge is in contact with the shell.

[0016] A further preferred solution of the present invention is that an air inlet is provided on the top surface of the shell, and the diameter of the air inlet is smaller than the diameter of the air pump.

[0017] The cleaning machine is provided with the air pump assembly inside.

[0018] Compared with the prior art, the advantage of the present invention is that the air pump is installed in the shell. The present invention effectively avoids direct contact between the air pump and the sealing ring and the external humid environment through the setting of the shell. The service life of the air pump is effectively extended. The upper end of the air pump is installed in the shell through the sealing ring. On the one hand, the installation of the upper end of the air pump is stable, and on the other hand, it avoids the air pump from colliding with the inner wall of the shell and making abnormal noises due to its own vibration during use. In summary, the structural setting of the present invention provides a reasonable installation environment for the air pump and extends its service life; the added vibration reduction structure reduces the noise generated by the operation of the air pump.

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 1 、 Figure 2 As shown: an air pump assembly includes a shell 1 and an air pump 2. A sealing ring is provided at the upper end of the air pump 2, and the upper end of the air pump 2 is installed in the shell through the sealing ring.

[0028] The sealing ring includes an upper gasket 3 and a lower gasket 4 . The upper gasket 3 is located on the top surface of the air pump 2 , and the lower gasket 4 is wrapped around the outer circumference of the air pump 2 .

[0029] The top surface of the upper gasket 3 is in contact with the housing 1. That is, the top surface of the air pump 2 is in contact with the housing 1 through the upper gasket 3. The upper gasket 3 avoids the possibility of contact and collision between the top of the air pump 2 and the housing 1.

[0030] The outer wall of the lower gasket 4 is in contact with the inner wall of the housing 1. That is, the outer periphery of the air pump 2 is in contact with the housing 1 through the lower gasket 4. The lower gasket 4 avoids the possibility of contact and collision between the outer periphery of the air pump 2 and the housing 1.

[0031] A connecting piece 5 extends outward from the bottom surface of the upper gasket 3, wrapping around the top surface of the air pump 2. The outer periphery of the connecting piece 5 is connected to the top surface of the lower gasket 4. The connecting piece 5 further wraps around the outer ring of the top surface of the cylinder and connects the upper gasket 3 and the lower gasket 4 to form an integral structure.

[0032] In addition to the upper washer 3, the present invention further provides a structural member with a vibration damping and buffering effect. Figures 3 and 4As shown, a plurality of tubular members 6 are vertically arranged on the connecting piece 5 , and the plurality of tubular members 6 are evenly distributed around the outer circumference of the upper gasket 3 .

[0033] Further, connecting edges 7 are extended from both sides of the tubular member 6 to connect with the outer wall of the upper washer 3. The tubular member 6 is connected to the upper washer 3 so that the two can share the force with each other.

[0034] Furthermore, the top surface of tubular member 6 is flush with the top surface of upper gasket 3 and in contact with housing 1. The top surface of connecting edge 7 is flush with the top surface of upper gasket 3 and in contact with housing 1. This structure of tubular member 6 and connecting edge 7 further decomposes the forces acting on the upper end face of the sealing ring. Forces acting on the upper end face of the sealing ring are shared among upper gasket 3, tubular member 6, and connecting edge 7, resulting in a superior vibration damping effect for the sealing ring.

[0035] In addition, the bottom of the lower gasket 4 of the present invention is provided with a circle of undercuts 8, and the undercuts 8 are clamped into the air pump 2. Figure 2 and Figure 4 It can be seen that the structure of the air pump 2 of the present invention allows the undercut 8 to be snapped into the air pump 2, thereby increasing the stability of the connection between the sealing ring and the air pump 2. Similarly, if a circle of indentation is provided on the surface of the air pump 2, the undercut 8 can also be snapped into the air pump 2, which is a simple variation of the present invention.

[0036] like Figure 2 As shown, the top surface of the present invention is not a flat structure, so the inner ring of the connecting piece 5 of the ring structure is higher than the outer ring. And a circle of gasket 9 is set on the bottom surface of the connecting piece 5, and the inner side of the gasket 9 is embedded in the top surface of the air pump 2. Figure 2 As can be seen in the figure, the outer periphery of the top surface of the air pump 2 is also provided with a circle of indentation, for the backing ring 9 to be embedded in its top surface. The backing ring 9 of the present invention is provided to further increase the vibration damping and buffering effect of the air pump 2 in the circumferential direction.

[0037] During operation, the air pump 2 itself will vibrate. If the air pump 2 directly contacts the housing 1, collisions will occur, producing unusual noises. Therefore, the present invention provides a sealing ring on the upper portion of the air pump 2. This allows the upper portion of the air pump 2 to rest against the inner wall of the housing 1 through the sealing ring, and the top surface of the air pump 2 to rest against the plate inside the housing 1 through the sealing ring. This provides good installation stability, and the air pump 2 does not directly contact the structure inside the housing 1, avoiding collisions and unusual noises.

[0038] Similarly, the present invention provides a sealing gasket 10 at the bottom of the air pump 2, and a ring-shaped mounting seat 11 is provided on the inner bottom surface of the housing 1. The air pump 2 is mounted on the mounting seat 11 through the sealing gasket 10. The air pump 2 does not directly contact the structure inside the housing 1, avoiding collision and generating abnormal noise.

[0039] The top surface of the housing 1 is provided with an air inlet, the diameter of which is smaller than the diameter of the air pump 2. That is, the housing structure of the present invention has a closed top, which can meet the air intake requirements of the air pump 1 while preventing water from entering the housing 1.

[0040] For ease of assembly, the housing 1 of the present invention is composed of a lower shell and an upper shell. During assembly, the air pump 2 can be simply assembled with the sealing gasket 10, then installed into the mounting seat 11 of the lower shell, the sealing ring is installed on the air pump 2, and finally the upper shell and lower shell are connected to complete the overall assembly of the present invention.

[0041] The cleaning machine is provided with the air pump assembly. The cleaning machine has the above-mentioned technical effects, such as low noise and long service life.
