Description

Technical Field

[0001] The utility model relates to the field of electrical appliances, in particular to a diaphragm pump assembly and a household appliance comprising the diaphragm pump assembly. Background Art

[0002] With the comprehensive development of the home appliance industry, more and more products use gas diaphragm pumps, especially micro gas diaphragm pumps. However, gas diaphragm pumps are reciprocating pumps, which will produce relatively large vibrations during operation, affecting the customer experience.

[0003] At present, the diaphragm pumps on the market mainly use springs for shock absorption. This type of diaphragm pump is prone to component wear during use. At the same time, as the spring is used for a longer time, the spring will experience plastic deformation, oxidation corrosion and other problems, which will weaken the spring elasticity and reduce the shock absorption effect of the product.

[0004] Therefore, there is still a need for a diaphragm pump product that solves at least some of the above problems and has a simple structure. Utility Model Content

[0005] In view of the above problems, according to the first aspect of the utility model, a diaphragm pump assembly is proposed, the diaphragm pump assembly includes a diaphragm pump, a suspension member and a housing, wherein the diaphragm pump is connected to the suspension member to be suspended inside the housing through the suspension member, wherein the connection between the diaphragm pump and the suspension member is non-rigid and / or at least a portion of the suspension member is non-rigid. In the diaphragm pump assembly according to the first aspect of the utility model, the suspension member can absorb and buffer the vibration from the diaphragm pump, thereby reducing the vibration transmitted to the housing. Therefore, the diaphragm pump assembly can effectively reduce or even avoid the transmission of the vibration of the diaphragm pump to the outside of the diaphragm pump assembly, thereby providing an improved shock absorption effect for the equipment equipped with the diaphragm pump assembly, while improving the user experience.

[0006] The diaphragm pump assembly according to the present invention may have one or more of the following features alone or in combination.

[0007] According to one embodiment, preferably, a shock absorbing block is fixedly mounted on the diaphragm pump. The diaphragm pump assembly according to this embodiment increases the weight of the diaphragm pump, and combined with the suspension arrangement of the diaphragm pump in the diaphragm pump assembly, the shock absorbing effect of the diaphragm pump assembly is further improved.

[0010] According to one embodiment, preferably, the damping block is made of metal. This embodiment is a preferred embodiment of the utility model, which improves the damping effect of the diaphragm pump assembly and ensures that the diaphragm pump assembly is small in size by using a metal material with a high density to manufacture the damping block, while having a relatively simplified manufacturing process.

[0011] According to one embodiment, preferably, the diaphragm pump includes a motor, a pump chamber, a transmission component and a diaphragm pump housing, the motor and the pump chamber are attached to the diaphragm pump housing, the transmission component transmits the drive from the motor to the pump chamber by moving basically in a plane, and the shock-absorbing block is fixedly mounted to the diaphragm pump housing. This embodiment is a preferred embodiment of the utility model, which further improves the shock-absorbing effect of the diaphragm pump assembly.

When the damping block is arranged along the outer surface of the diaphragm pump housing, it helps to simplify the installation process of the damping block.

[0014] According to one embodiment, preferably, the shock absorbing block is installed at the bottom of the diaphragm pump housing. This embodiment is a preferred embodiment of the utility model.

This embodiment is a preferred embodiment of the utility model, and the damping effect can be particularly improved by setting the horizontal dimension of the damping block as above.

[0016] According to one embodiment, preferably, the damping block is installed on the lateral side of the diaphragm pump housing.

[0020] According to one embodiment, it is preferably characterized in that the suspension member is made of a non-rigid material. According to the diaphragm pump assembly of this embodiment, the suspension member can have a simple structure while ensuring that the suspension member has a non-rigid property.

[0070] The present invention will be described in detail below by describing exemplary embodiments.

[0071] Figure 1A and Figure 1B The diaphragm pump 100 of the diaphragm pump assembly 10 according to one embodiment of the utility model is shown in an exploded view. Figure 1B Relative to Figure 1A The perspective of FIG. 1 is slightly offset to further illustrate the structure of the various components of the diaphragm pump 100. Figure 1A and Figure 1BAs shown, the diaphragm pump 100 includes a motor 110, a pump chamber 120 and a transmission mechanism, wherein the transmission mechanism receives a drive from the motor 110 to drive the pump chamber 120. The diaphragm pump 100 also includes a diaphragm pump housing 150, to which the motor 110 and the pump chamber 120 are attached. For ease of description, the side of the diaphragm pump housing 150 where the pump chamber 120 is arranged is referred to as the front side, the side opposite to the front side is referred to as the rear side, and the direction between the front side and the rear side is referred to as the front-to-back direction. The diaphragm pump housing 150 can be formed by assembling a diaphragm pump housing frame 151 and a diaphragm pump housing cover 152.

[0072] like Figure 1A and Figure 1B Specifically, the pump chamber 120 includes a front pump body 121, a rear pump body rib 122, a valve sheet 123, a rear pump body 124, a pressure plate 125 and a diaphragm sheet 126. When assembling the pump chamber 120, the front pump body 121, the rear pump body rib 122, the rear pump body 124, the pressure plate 125, the diaphragm sheet 126 and the transmission component 130 are arranged in sequence. On the one hand, the front pump body 121 is provided with an air inlet 127 and an air outlet 128, and the rear pump body 124 is provided with corresponding air inlet holes and air outlet holes, respectively, and the rear pump body rib 122 is formed as a component that can be arranged on the surface of the rear pump body 124 around the air inlet holes and the air outlet holes, respectively. The front pump body 121, the rear pump body rib 122 and the rear pump body 124 are fixed together by screws, wherein the rear pump body rib 122 is arranged between the front pump body 121 and the rear pump body 124, so that the front pump body 121, the rear pump body rib 122 and the rear pump body 124 can jointly form an inlet channel and an outlet channel for the fluid. On the other hand, the pressing plate 125, the diaphragm 126 and the transmission component 130 are fixed to each other by screws on the pressing plate 125, and the rear pump body 124 fixes the edge of the diaphragm 126 on the opening of the diaphragm pump housing 150, thereby forming a chamber between the side of the rear pump body 124 facing away from the front pump body 121 and the pressing plate 125 and the diaphragm 126 fixed to each other, and the chamber can be communicated with the external fluid through the air inlet and the air outlet on the rear pump body 124. The valve plate 123 is respectively arranged at the air inlet and the air outlet on the rear pump body 124 to control the flow direction of the fluid.

[0073] Reference Figure 2A and Figure 2B The diaphragm pump housing 150 accommodates the transmission component 130 and at least a portion of the pump chamber 120. The diaphragm 126 is elastic, for example, made of rubber. Therefore, by the transmission component 130 pushing the diaphragm 126 toward the front pump body 121 and pulling the diaphragm 126 away from the front pump body 121, the volume of the chamber changes, and the pump chamber 120 discharges and inhales air to pump gas.

[0074] Figure 2A , Figure 2B and Figure 3The transmission mechanism is further shown. Figure 2A , Figure 2B and Figure 3 As shown, the transmission mechanism includes a bearing 141, an eccentric wheel 142, a counterweight 143 and a transmission component 130. Specifically, the eccentric wheel 142 is cylindrical, and has an interference fit with the motor shaft 111 of the motor 110 through its eccentrically arranged through hole. The inner ring of the bearing 141 has an interference fit with the radial outer surface of the eccentric wheel 142, and the outer ring of the bearing 141 has an interference fit with the transmission component 130, for example, an interference fit with the radial inner surface of the through hole of the transmission component 130. Therefore, one end (driving part 133) of the transmission component 130 is fixedly connected to the diaphragm 126 of the pump chamber 120, and the other end (driven part 132) is connected to the motor shaft 111 of the motor 110 through the bearing 141 and the eccentric wheel 142, so that the transmission component 130 can transmit the drive of the motor 110 to the pump chamber 120, driving the chamber volume of the pump chamber 120 to change. In this configuration, the transmission member 130 is generally in a plane perpendicular to the rotation axis of the motor shaft 111 ( Figure 2A and Figure 2B In addition, the counterweight 143 can be fixedly sleeved on the radial outer side of the eccentric wheel 142, for example, by interference fit, so as to reduce or eliminate the vibration of the diaphragm pump 100 caused by the movement of the eccentric wheel 142.

[0075] like Figure 2A As shown, the transmission component 130 can be installed so that its main body 131 extends roughly along the line direction between the diaphragm 126 and the motor shaft 111 (i.e., roughly along the front-back direction), the driven portion 132 of the transmission component 130 is provided with a through hole that is interference-fitted with the outer ring of the bearing 141, and the driving portion 133 of the transmission component 130 is formed as a disc to be fixed to the roughly center position of the diaphragm 126. The transmission component 130 can also be called a connecting rod.

[0076] The applicant has found that the movement of the transmission component 130 in the diaphragm pump 100 has a significant effect on the vibration performance of the diaphragm pump 100. Specifically, one reciprocating motion of the transmission component 130 produces one air intake and one air discharge, that is, one cycle. Since the counterweight block 143 is installed on the eccentric wheel 142, the motor 110 itself can reach a higher speed and frequency. However, the high-speed reciprocating transmission component 130 will drive the diaphragm pump 100 to generate greater vibration. For this reason, according to the utility model, a shock-absorbing block 400 is fixedly installed on the diaphragm pump 100 to reduce the vibration transmitted to the outside by the diaphragm pump 100.

[0077] like Figure 1A , 1B and Figure 2A , 2B As shown, a plate-shaped damping block 400 is fixedly mounted on the diaphragm pump 100. Figure 1A , 1B and Figure 2A In the embodiment of the present invention, a shock absorbing block 400 is provided, which has a uniform thickness and is arranged at the bottom of the diaphragm pump housing 150 along the outer surface of the diaphragm pump housing 150. Figure 2B In the embodiment, three plate-shaped damping blocks 400 are arranged inside the diaphragm pump housing 150 and are arranged along the inner surface of the diaphragm pump housing 150 at the bottom and two lateral sides of the diaphragm pump housing 150 to form a U-shape. Figure 4 In the embodiment, two plate-shaped damping blocks 400 are provided, which are arranged outside the diaphragm pump housing 150, respectively located on two opposite lateral sides between the front side and the rear side. Therefore, according to the embodiment of the utility model, one or more damping blocks 400 can be arranged along the inner surface and / or outer surface of the diaphragm pump housing 150, and one or more damping blocks 400 can be installed at the bottom and / or lateral sides of the diaphragm pump housing 150. The damping blocks 400 can be fixed to the diaphragm pump housing 150, for example, by bolt connection, welding, gluing, etc. The damping blocks 400 can also be embedded in the corresponding recessed portions on the diaphragm pump housing 150 and fixed therein, and the above fixing methods can also be used in combination.

[0078] In addition, according to an embodiment not shown in the utility model, the shock absorbing block 400 may also have other shapes, for example, the shock absorbing block 400 as an integral component is fixedly arranged on the diaphragm pump 100, and the shock absorbing block 400 is arranged along the bottom and at least one lateral side of the diaphragm pump housing 150. Such a shock absorbing block 400 can be formed as a U-shape or an L-shape as a whole. When the shock absorbing block 400 is in a U-shape, the parts at both ends thereof can be respectively located on two opposite lateral sides between the front side and the rear side of the diaphragm pump housing 150, and are constructed symmetrically to each other. Similarly, the shock absorbing block 400 as an integral component can be fixed to the diaphragm pump housing 150, for example, by bolt connection, welding, gluing, etc., or embedded in a corresponding recessed portion arranged on the diaphragm pump housing 150 and fixed therein, and the above fixing methods can also be used in combination.

[0079] The damping block 400 is fixedly installed on the diaphragm pump 100, which can be regarded as adding the overall weight to the diaphragm pump 100. The applicant has found that for a diaphragm pump mounted to an external device by, for example, a spring, when the diaphragm pump is equipped with the above-mentioned damping block, the vibration transmitted to the outside world will be reduced. When the diaphragm pump 100 is suspended inside the housing 300 by the suspension member 200 to be described in detail below, the damping block 400 is provided to further reduce the vibration transmitted from the diaphragm pump 100 to the housing 300, thereby reducing the impact of the vibration of the diaphragm pump 100 on the external device. According to an embodiment of the utility model, the damping block 400 can be made of metal to increase the weight while ensuring the smaller volume of the diaphragm pump assembly 10 as a whole. According to other embodiments of the utility model, the weight of the damping block 400 can be greater than 30% of the weight of the diaphragm pump 100, in particular greater than 50% of the weight of the diaphragm pump 100, and in particular greater than 70% of the weight of the diaphragm pump 100. The shock absorbing block 400 may be made of other materials with higher density. For example, the density of the shock absorbing block 400 is greater than the density of the material forming the diaphragm pump housing 150 .

[0080] The installation of the damping block 400 also adjusts the mass distribution of the diaphragm pump 100 as a whole. Generally, the damping block 400 applies a vertical downward force to the diaphragm pump housing 150, thereby applying a vertical downward force to the entire diaphragm pump 100. The applicant has found that the damping blocks 400 (such as the damping blocks 400 disposed on opposite sides of the diaphragm pump housing 150) Figure 4 ) can reduce the transmission of vibration of the diaphragm pump 100 along the front-to-back direction, while the shock-absorbing block 400 arranged at the bottom of the diaphragm pump housing 150 can reduce the transmission of vibration of the diaphragm pump 100 in the entire horizontal direction (i.e., the lateral direction). Further, according to an embodiment of the utility model, when the shock-absorbing block 400 is installed at the bottom of the diaphragm pump housing 150, the shock-absorbing block 400 is along the plane where the movement of the transmission component 130 is located (such as Figure 2A and Figure 2B The dimension in the direction parallel to the horizontal plane in the middle) can be larger than the stroke range of the transmission component 130 in the corresponding direction, that is, the range that the transmission component 130 can cover in the corresponding direction during the reciprocating motion.

[0081] Figure 5 A cross-sectional view of a diaphragm pump assembly 10 according to the present invention is shown. Figure 5 The shaded structure in the middle schematically shows a diaphragm pump 100, which is disposed in a housing 300. The housing 300 may be composed of an upper half 310 and a lower half 320, for example, a protrusion at the opening edge of the upper half 310 may be embedded in a groove at the opening edge of the lower half 320. The upper half 310 and the lower half 320 of the housing 300 together enclose an interior 301 of the housing 300.

[0082] exist Figure 5 In the embodiment, a plate-shaped damping block 400 is fixedly installed below the diaphragm pump 100, and the damping block 400 extends beyond the diaphragm pump 100 to be connected to the suspension member 200. The suspension member 200 is connected between the damping block 400 and the inner top of the upper half 310 of the housing 300, thereby suspending the damping block 400. In other words, the diaphragm pump 100 is indirectly connected to the suspension member 200 to be suspended inside the housing 300 through the suspension member 200. Figure 5 In the cross-sectional view of FIG. 1 , only two suspension members 200 of the diaphragm pump assembly 10 are shown, which are located at the front and rear sides of the diaphragm pump 100 (i.e., the left and right sides in the figure). Figure 5 In the corresponding embodiment, a suspension member 200 is respectively provided at each of the four corners of the plate-shaped shock-absorbing block 400, so that the four suspension members 200 can suspend the diaphragm pump 100 in the housing 300, and the diaphragm pump 100 is easy to maintain balance. It should be understood that each outer side of the diaphragm pump 100 should be kept at a certain distance from the inner wall of the housing 300, so that when the diaphragm pump 100 is working and vibrates itself, its vibration will not cause it to hit the inner wall of the housing 300.

[0083] Figure 5 The figure also specifically shows an air inlet pipe 501, one end of which is connected to the air inlet of the diaphragm pump 100, and the other end is connected to the protruding fixed pipe at the inner top of the upper half 310 of the housing 300, and is in fluid communication with the fixed pipe, so that the fluid inside the pump chamber 120 can be communicated with the outside. The air inlet pipe 501 can be fixed to the fixed pipe by a clamp 505. At the same time, the suspension member 200 can also be formed by the same pipe member as the air inlet pipe 501 and the air outlet pipe 502. In this way, the two ends of the suspension member 200 can be respectively sleeved to the protruding support portion 201 provided on the damping block 400 and the corresponding support portion at the inner top of the upper half 310 of the housing 300, and are fixed by the clamp 505 respectively. It should be understood that the connection method of the suspension member 200 with the damping block 400 and the top of the housing 300 is not limited to the clamp, and can also be used in the form of a buckle, a ball shaft, a bull's eye rod, etc. In addition, if the damping block 400 is disposed outside the diaphragm pump housing 150 but has other specific shapes, the suspension member 200 can still be connected to the damping block 400 to suspend the diaphragm pump 100 accordingly.

[0084] Fig. 6A and Figure 6B A perspective view and a cross-sectional view of the diaphragm pump assembly 10 of this embodiment are respectively shown, and the lower half of the housing 300 is not shown for clarity of illustration. Fig. 6A and 6BThree of the four suspension members 200 are further shown. Providing four suspension members 200 to surround the air inlet pipe 501 and the air outlet pipe 502 can reduce the tensile force on the air inlet pipe 501 and the air outlet pipe 502, thereby reducing the risk of the air inlet pipe 501 and the air outlet pipe 502 falling off. The four suspension members 200 can have the same structure and be connected to the inner top of the shock absorbing block 400 and the housing 300 in the same way, thereby facilitating the balanced installation of the diaphragm pump 110. It should be noted that Figure 5 and Fig. 6A , 6B as well as Fig. 7A , 7B Only some embodiments of the present invention are shown. In fact, the suspension member 200 can be made of other materials and structures, as long as at least a part of it is non-rigid. Alternatively, the connection between the diaphragm pump 100 and the suspension member 200 can be non-rigid. The embodiments of the above figures can reduce the number of parts by manufacturing the suspension member using the same pipe component as the inlet pipe and the outlet pipe. The suspension member 200 can also be made of other non-rigid materials to have greater flexibility in the design and manufacturing process.

[0085] exist Figure 5 and Fig. 6A , 6B In the embodiment, the damping block 400 is fixedly mounted to the outside of the diaphragm pump housing 150, and the suspension member 200 is connected to the diaphragm pump 100 only through the damping block 400. In another embodiment, as Fig. 7A and Figure 7B As shown, the damping block 400 is still fixedly mounted to the outside of the diaphragm pump housing 150. Fig. 7A and Figure 7B In the figure, at the rear side of the diaphragm pump 100 (right side in the figure), the suspension member 200 is connected between the shock absorbing block 400 and the inner top of the upper half 310 of the housing 300, and at the front side of the diaphragm pump 100 (left side in the figure), the air inlet pipe 501 and the air outlet pipe 502 play the role of the suspension member 200. In other words, the air inlet pipe 501 and the air outlet pipe 502 also form at least a part of the multiple suspension members, and the air inlet pipe 501, the air outlet pipe 502 and the two suspension members 200 at the rear side of the diaphragm pump 100 jointly suspend the diaphragm pump 100 inside the housing 300. Among them, the connection between the air inlet pipe 501 and the air outlet pipe 502 and the air inlet and outlet includes but is not limited to socketing, buckle, clamp and other methods, and the connection between the air inlet pipe 501 and the air outlet pipe 502 and the top of the housing 300 includes but is not limited to buckle, clamp, ball shaft, bull's eye rod and other methods. Such a configuration utilizes the structural features of the diaphragm pump 100 itself, can reduce the number of installation positions of the suspension member 200 , and reduce the difficulty of processing and installation.

[0086] Thus, according to the present invention, at least a portion of the plurality of suspension members 200 may be connected to the shock absorbing block 400 to suspend the diaphragm pump 100. On the other hand, the suspension member 200 may also be connected between the diaphragm pump 100 itself and the top of the housing 300, in which case the diaphragm pump 100 is directly connected to the suspension member 200 to be suspended inside the housing 300 through the suspension member 200.

[0087] Since the diaphragm pump 100 is suspended in the housing 300 in the above-mentioned arrangement, when the housing 300 is arranged in a corresponding device, for example, when the housing 300 is installed inside a household appliance (such as a washing machine, a dishwasher, a refrigerator, etc.), the suspension member 200 will absorb and buffer the vibration transmitted from the diaphragm pump 100 to the housing 300, thereby further reducing the impact of the vibration of the diaphragm pump 100 on external equipment. At the same time, installing the above-mentioned damping block 400 on the diaphragm pump 100 itself can also reduce the impact of the vibration of the diaphragm pump 100 on the outside. Therefore, a household appliance equipped with the diaphragm pump assembly 10 according to the utility model can have further reduced vibration.

[0088] The exemplary embodiments of the diaphragm pump assembly and the household appliance proposed in the utility model are described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the utility model, various modifications and alterations can be made to the above specific embodiments, and various technical features and structures proposed in the utility model can be combined in various ways without exceeding the protection scope of the utility model.
