[0026] Due to the provision of the vents in the housing, external liquid (such as rainwater) can easily enter the housing, thereby affecting the components in the housing and further affecting the service life of the pump device.

[0027] In order to solve the above technical problems, refer to Figures 1-4 , Figure 1 A schematic structural diagram of a pump device provided in an embodiment of the present application is shown. Figure 2 Show Figure 1 The enlarged view of part A is shown. Figure 3 A cross-sectional view of a pump device provided in an embodiment of the present application is shown. Figure 4 Show Figure 3 An enlarged view of part B is shown.

[0028] The present application provides a shell 1, which is used to cover a pump body 2. The side wall of the shell 1 is provided with a vent for air flow outside the shell 1, and a grille 3 is provided in the vent. The grille 3 includes a plurality of gratings 31, and the plurality of gratings 31 are arranged at intervals. The plane where the gratings 31 are located is a first plane, and the plane where the side wall at the vent is located is a second plane. The internal angle between the first plane and the second plane is angle α, and 0°<angle α<90°.

[0029] It should be understood that the pump device of the present application is arranged outside the liquid. In order to protect the pump device, the present application includes a shell 1 and a pump body 2. The present application does not limit the shape of the shell 1. The shell 1 can be any shape such as a rectangular parallelepiped or a cylindrical shape. The shell 1 is provided with an inner cavity. The inner cavity of the shell 1 is used to cover the pump body 2, thereby reducing the impact of external foreign matter on the pump body 2 and improving the service life of the pump body 2. The pump body 2 includes a motor 21 and a hydraulic component 22 connected to the motor 21. The motor 21 is connected to a heat dissipation fan to dissipate heat from the pump body 2.

[0030] This application does not limit the material of the housing 1, but in order to further improve the protection of the pump body 2, the housing 1 is made of plastic, which is lighter and less prone to decay than metal, and can also provide insulation protection. The housing 1 is provided with a vent that penetrates the side wall of the housing 1 to facilitate the exchange of air within the housing 1 with the outside air, thereby dissipating heat from the pump body 2 and improving the service life of the pump body 2. The shape of the vent is not limited here, and the vent can be any shape, such as a triangle, rectangle, pentagon, etc.

[0031] The vent is provided with a grille 3 comprising a plurality of spaced-apart gratings 31. These gratings 31 are spaced apart to divide the vent into a plurality of strip-shaped apertures. External air is exchanged with the air within the housing 1 through these strip-shaped apertures, thereby not interfering with the heat dissipation of the pump body 2. The grille 3 can be fixedly or detachably connected to the housing 1, without limitation in this application. The grilles 3 do not protrude from the sidewalls of the housing 1, to avoid interference with packaging and handling, and to prevent scratches from protruding portions.

[0032] In one example, the grille 3 is detachably connected to the shell 1, that is, a plurality of gratings 31 are arranged at intervals to form a grille, and then the grille 3 is installed at the vent of the shell 1. The installation method can be through bolt connection, or through snap connection, plug-in connection, etc.

[0033] In one example, the material of the grid plate 31 is the same as that of the housing 1 , and the grid plate 31 and the housing 1 are integrally formed, thereby forming the grille 3 at the vent of the housing 1 .

[0034] The grating 31 is arranged in a plate shape, with the plane where the grating 31 is located being a first plane, and the plane where the sidewall at the vent is located being a second plane. The first plane and the second plane are arranged at an angle, and the internal angle between the first plane and the second plane is an angle α, where 0°<angle α<90°, and the angle α can be 10°, 30°, 45°, 60°, 80°, or 85°. The angle α is set so that the strip holes between the two gratings 31 are arranged at an angle, so that air inside the housing 1 and / or air outside the housing 1 enter and exit the housing 1 at a certain angle, and the angle of the strip holes is set by the angle α between the first plane and the second plane. The angle between the first plane and the second plane can reduce the entry of foreign matter (such as rainwater) into the housing 1 without affecting the exchange of air inside the housing 1 with air outside the housing 1, thereby improving the waterproof effect of the housing 1 and reducing the impact of foreign matter on the pump body 2 inside the housing 1, thereby increasing the service life of the pump device.

[0035] Furthermore, there is no restriction on the length direction of the grid plate 31. The length direction of the grid plate 31 can be set parallel to the bottom surface of the shell 1, that is, multiple grid plates 31 are arranged at intervals along the height direction of the shell 1; the length direction of the grid plate 31 can also be set parallel to the side wall of the shell 1, that is, multiple grid plates 31 are arranged at intervals along the length or width direction of the shell 1; the length direction of the grid plate 31 can also be set at an angle to the bottom surface of the shell 1 and the side surface of the shell 1, and multiple grid plates 31 are arranged at intervals along another direction.

[0036] In some optional embodiments, the angle α is equal to 45°. At this angle, the strip hole will not be too narrow, reducing the obstruction of the exchange of air inside the shell 1 and the air outside the shell 1. It can also better block external foreign matter and improve the waterproof effect of the shell 1.

[0037] In some optional embodiments, the opening at the angle α faces the top of the housing 1 , thereby preventing water on the ground from entering the inner cavity of the housing 1 .

[0038] In some optional embodiments, the opening at angle α faces the bottom of the housing 1. Since rainwater falls from the sky, in order to further reduce rainwater from entering the housing 1, the opening at angle α faces downward, thereby improving the waterproof effect of the housing 1.

[0039] In some optional embodiments, the vent is rectangular, the grating 31 is parallel to one diagonal of the vent, and the plurality of gratings 31 are spaced apart along the direction extending from the other diagonal of the vent. The vent is rectangular, i.e., the vent has two intersecting diagonals, the length direction of the grating 31 is parallel to one of the diagonals, and the plurality of gratings 31 are spaced apart along the direction extending from the other diagonal. Compared to the arrangement in which the length direction of the grating 31 is parallel to the bottom wall of the housing 1 or the side walls of the housing 1, the arrangement in this application can further increase the number of gratings 31, thereby improving the waterproofing effect of the housing 1. Furthermore, the length direction of the grating 31 is inclined relative to the bottom wall of the housing 1, so that the grating 31 is also inclined relative to the angle at which rainwater falls, further improving the waterproofing effect of the housing 1.

[0040] In some optional embodiments, the vent includes an air inlet 111 and an air outlet 112. The air inlet 111 is located at the motor end of the housing 1 close to the pump body 2. The side wall of the housing 1 facing away from the motor of the pump body 2 is the first side wall 12. The air outlet 112 is located at the first side wall 12. The vent includes the air inlet 111, and the outside air enters the inner cavity of the housing 1 from the air inlet 111. The vent also includes the air outlet 112, and the air in the inner cavity of the housing 1 flows out of the housing 1 from the air outlet 112 to achieve the exchange of air in the inner cavity of the housing 1 with air in the outer cavity of the housing 1. This application does not limit the number of air inlets 111, and the air inlet 111 can be one, two, or more. This application also does not limit the number of air outlets 112, and the air outlet 112 can be one, two, or more.

[0041] The air inlet 111 is located at the motor end of the housing 1 close to the pump body 2, and the air outlet 112 is located on the first side wall 12, so that the air flow path in the housing 1 is the longest, further improving the heat dissipation effect of the pump body 2.

[0042] Reference Figure 1 and Figure 3 In some optional embodiments, the housing 1 is provided with a human-machine interface 4. The human-machine interface 4 is located at the motor end of the housing 1 near the pump body 2. The side wall of the housing 1 facing away from the first side wall 12 is the second side wall 13. Two air inlets 111 are provided, one on each side of the second side wall 13. The housing 1 is provided with the human-machine interface 4, which allows the operator to control the pump device through the human-machine interface 4 and also facilitates the operator to understand the operating status of the pump device through the human-machine interface 4.

[0043] The human-machine interface 4 is located on the top wall of the housing 1, near the motor end of the pump body 2. The interface 4 also partially extends to the second side wall 13. When the operator needs to operate the human-machine interface 4, the operator is at the second side wall 13. To prevent the operator from blocking the air inlet 111, the air inlet 111 is located on the side of the second side wall 13, thereby improving the air intake efficiency of the air inlet 111. To further improve the exchange of external air with the air inside the housing 1, two air inlets 111 are provided, one on each side wall of the second side wall 13.

[0044] In some optional embodiments, the distance between the motor of the pump body 2 and the second side wall 13 is a distance L, where L is ≥ 40 mm. Distance L can be set to 40 mm, 50 mm, or other distances, and is not limited in this application. When L is less than 40 mm, the space between the pump body 2 and the second side wall 13 is insufficient, which can easily block the air inlet 111, affecting the air intake at the air inlet 111 and improving the heat dissipation of the pump body 2.

[0045] In some optional embodiments, the housing 1 further includes a detachably connected cover 14 and base 15. The base 15 is provided with a drain port 151, and the drain ports 151 are provided in multiple, spaced-apart configurations. The cover 14 and base 15 are detachably connected to facilitate placement of the pump body 2 into the inner cavity of the housing 1. The connection between the cover 14 and base 15 can be by plugging, snapping, or bolting, which is not limited in this application. The air inlet 111 and air outlet 112 are both provided on the cover 14, and the grille 3 is also provided on the cover 14.

[0046] Base 15 is provided with a drain port 151 extending through the thickness of base 15 to connect base 15 with the outside world and facilitate the drainage of liquid within base 15. In strong winds and rain, rainwater may seep into housing 1. In this case, rainwater can be drained through drain port 151 on base 15, preventing rainwater from accumulating in housing 1, reducing its impact on pump body 2 and extending the service life of pump body 2.

[0047] This application does not limit the shape of the drain port 151; the drain port 151 can be any shape, such as rectangular, triangular, or circular. Multiple drain ports 151 can be provided, for example, two, three, or four, with multiple drain ports 151 spaced apart to further improve the drainage efficiency of the housing 1. In one example, there are four drain ports 151, located at four corners of the pump body 2.

[0048] In some optional embodiments, the base 15 includes a bottom plate and a plurality of support parts, one end of the support part is connected to the bottom plate and the other end is in contact with the ground, so that the bottom plate is spaced apart from the ground. The material of the bottom plate is the same as that of the support part, that is, the bottom plate and the support part are integrally formed, and the support part can be a support column, for example, the support part is cylindrical and is respectively located at the circumference of the bottom plate to support the bottom plate, and the support part can also be in a grid shape or other shapes, which is not limited in this application. The drain port 151 is located at the bottom plate and passes through the bottom plate. The arrangement of the support part makes the bottom plate spaced apart from the ground, thereby making the drain port 151 spaced apart from the ground, so that the liquid flows more smoothly from the drain port 151, thereby improving the drainage effect of the drain port 151.

[0049] In some optional embodiments, the bottom plate is recessed away from the support portion to form a groove 152, and the groove 152 is for an operator to hold when carrying. Furthermore, two grooves 152 are provided and are located on opposite sides of the bottom plate.

[0050] Reference Figure 1-Figure 5 , Figure 5 A schematic structural diagram of a housing provided in an embodiment of the present application is shown.

[0051] In some optional embodiments, to facilitate the normal operation of the hydraulic components 22 in the pump body 2, the housing 14 is further provided with a liquid inlet 141 and a liquid outlet 142. To reduce the impact of impurities in the liquid on the pump body 2, a filter is provided at the liquid inlet 141 to filter the liquid. Markings may also be provided at the liquid inlet 141 and the liquid outlet 142 to facilitate installation by the operator.

[0052] In some optional embodiments, the cover body 14 is further provided with a plugging hole 143 , which is located at the air outlet 112 . The provision of the plugging hole 143 facilitates the disassembly and assembly of the screw plug.

[0053] Reference Figures 1-4 The present application also includes a pump body device, which includes a housing 1 as described in any of the above items and a pump body 2 located within the housing 1. The housing 1 is used to house the pump body 2. The side walls of the housing 1 are provided with vents for air flow outside the housing 1. The vents are provided with a grille 3. The grille 3 includes a plurality of grid plates 31. The plurality of grid plates 31 are spaced apart. The plane where the grid plates 31 are located is a first plane, and the plane where the side walls at the vents are located is a second plane. The internal angle between the first plane and the second plane is an angle α, where 0° < angle α < 90°. The pump body 2 includes a motor 21 and a hydraulic component 22 connected to the motor 21. The motor 21 is connected to a heat dissipation fan to dissipate heat from the pump body 2.

[0054] The first plane and the second plane are set at an angle α, 0°<angle α<90°. Without affecting the exchange of air inside the shell 1 with the air outside the shell 1, the setting of the grid 31 can also reduce the entry of foreign matter from the outside (such as rainwater) into the shell 1, thereby improving the waterproof effect of the shell 1 and reducing the impact of foreign matter (such as rainwater) on the pump body 2 inside the shell 1, thereby increasing the service life of the pump body device.

[0055] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
