[0003] As a core component of various inflatable products, the air pump plays the role of inflating the inflatable product and sucking out the gas inside the inflatable product. Traditional air pumps require users to manually switch between blowing and sucking modes, which brings inconvenience to users. Summary of the Invention

[0004] This application provides a built-in integrated suction and blowing air pump to solve the technical problem that traditional air pumps require users to manually switch between suction and blowing, which is inconvenient to operate.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a built-in integrated blower, which includes an air pump, a lead screw, a drive motor, a valve head, and a housing.

[0006] The air pump includes an air blowing port and an air suction port, both of which are equipped with a blocking part;

[0007] The lead screw is set horizontally, and the air pump and lead screw are slidably assembled.

[0008] The drive motor is used to drive the air pump to move laterally along the lead screw;

[0009] The valve head includes a blow valve head and a suction valve head, or the blow valve head and / or suction valve head can be replaced with a one-way valve.

[0010] The housing includes an air blowing port and an air extraction port, which are located on both sides of the housing. The air pump is located inside the housing, and the valve heads are located at the positions of the air blowing port and the air extraction port, respectively.

[0011] In the process of the air pump being driven by the drive motor to move along the lead screw towards the air blowing valve head, the blocking part at the air blowing port position abuts against the air blowing valve head to open the air blowing hole, or a one-way air valve is set at the air blowing hole so that the air pump can blow air to the outside through the air blowing hole.

[0012] During the process of the air pump being driven by the drive motor to move along the lead screw towards the air extraction valve head, the blocking part at the air extraction port position abuts against the air extraction valve head, opening the air extraction hole, or a one-way air valve is set at the air extraction hole, so that the air pump can extract air from the outside through the air extraction hole.

[0013] In one specific embodiment of this application, the air blowing port, air extraction port, blocking part, valve head, air blowing hole and air extraction hole are all located at the same horizontal height.

[0014] In a specific embodiment of this application, the blowing valve head and the suction valve head have the same structure, both including a mounting part, a spring, a rubber plug and an air-blocking plug. The blowing valve head and the suction valve head are fixedly assembled to both sides of the housing through the mounting part, or the blowing valve head and / or the suction valve head can be replaced with a one-way valve.

[0015] In one specific embodiment of this application, the air stopper includes an air stopper disc, a rubber plug, and the air stopper disc being tightly joined together. The rubber plug and the air stopper disc have the same shape and both match the shape of the air blowing hole and the air extraction hole. The rubber plug and the air stopper disc are used to block the air blowing hole and the air extraction hole.

[0016] In one specific embodiment of this application, the housing further includes a sleeve, which is disposed at the positions of the air blowing hole and the air drawing hole. The sleeve includes a first limiting surface, which is used to limit the extreme positions of the air pump movement.

[0017] In one specific embodiment of this application, the built-in integrated blower also includes a reduction gear set, and the drive motor drives the air pump to move laterally through the reduction gear set. The reduction gear set is used to reduce the transmission speed of the drive motor.

[0018] In one specific embodiment of this application, the built-in blower also includes a cover, the housing has a first opening, the shape of the cover matches the shape of the first opening, the cover is fixedly assembled at the first opening of the housing, and the air pump is located in the space enclosed by the cover and the housing.

[0019] In one specific embodiment of this application, the surface of the cover is provided with a ventilation groove, through which gas freely enters and exits the space enclosed by the cover and the shell.

[0020] In one specific embodiment of this application, the cover is provided with fixed teeth, and the fixed teeth and the reduction gear set are geared together. When the drive motor drives the reduction gear set to rotate, the reduction gear set moves relative to the fixed teeth, thereby driving the air pump connected to the reduction gear set to move.

[0021] In one specific embodiment of this application, the built-in blower also has Bluetooth functionality, allowing users to control the built-in blower to blow and extract air via a Bluetooth device connected to it.

[0022] The beneficial effects of this application are as follows: During the process of the air pump being driven by the drive motor to move along the lead screw towards the air blowing valve head, the blocking part at the air blowing port position abuts against the air blowing valve head, opening the air blowing hole, so that the air pump can blow air to the outside through the air blowing hole. During the process of the air pump being driven by the drive motor to move along the lead screw towards the air extraction valve head, the blocking part at the air extraction port position abuts against the air extraction valve head, opening the air extraction hole, so that the air pump can extract air from the outside through the air extraction hole. This solves the problem of inconvenience caused by the need to manually switch between the air extraction and air blowing modes in traditional air pumps. Attached Figure Description

The lower end of the fixed shaft 730 is rotatably assembled with the fourth positioning hole 151. There are five fourth positioning posts 160, and their lengths increase sequentially from the fourth positioning post 160 closest to the drive motor 300 to the fourth positioning post 160 furthest from the drive motor 300. Four rectangularly distributed fifth positioning posts 170 are provided on both sides of the first receiving groove 150. A threaded hole is provided at the center of each fifth positioning post 170. Corresponding fourth assembly through holes 870 are provided on both sides of the assembly shell 800.

Sliding engagement portions 140 are provided on both sides of the upper end of the air pump 100. The sliding engagement portions 140 are horizontally arranged and are approximately cylindrical. The sliding engagement portions 140 on both sides are at the same horizontal height. The sliding engagement portions 140 include sliding mounting holes 141, which extend laterally through the sliding engagement portions 140. The shape of the sliding mounting holes 141 matches the shape of the lead screw 200. The lead screw 200 is cylindrical and extends horizontally through the sliding engagement portions and is slidably engaged with the sliding mounting holes 141. When the drive motor 300 drives the reduction gear set 700 to rotate, the gears in the reduction gear set 700 undergo a series of transmissions, causing the rotational speed of the displacement gear 740 to be less than the rotational speed of the drive gear 320 of the drive motor 300. When the displacement gear 740 rotates, it will move laterally due to the restriction of the fixed teeth 624, thereby driving the air pump 100 connected to the displacement gear 740 to move laterally along the lead screw.

[0055] At both ends of the lead screw 200, there are also a first fixing plate 210 and a second fixing plate 220. The first fixing plate 210 and the second fixing plate 220 are vertically spaced apart. The upper ends of the first fixing plate 210 and the second fixing plate 220 are provided with a fifth assembly through hole 230 that matches the second positioning hole 521 on the housing 400. The screw passes through the fifth assembly through hole 230 and the second positioning hole 521 to fix the first fixing plate 210 and the second fixing plate 220 to the housing 400. The lower ends of the first fixing plate 210 and the second fixing plate 220 are provided with mounting holes 240 that match the lead screw. The lead screw 200 is fixedly assembled with the first fixing plate 210 and the second fixing plate 220 through the mounting holes 240. The lower ends of the first fixing plate 210 and the second fixing plate 220 are also provided with a semi-circular notch 250 for the sleeve 530 part in the housing 400 to pass through.

[0056] The built-in blower pump 10 also includes a power module 900, which is vertically arranged. The power module 900 has a power connector at its upper end. A through groove 660 matching the shape of the power module 900 is provided on the surface of the cover plate 610.

Users can control the built-in blower pump 10 to blow and suck air through a Bluetooth device connected to the built-in blower pump 10. An assembly groove 211 is provided on the side of the first fixing plate 210 near the drive motor 300. The shape of the assembly groove 211 matches the shape of the power module 900. The power module 900 is fixedly assembled with the first fixing plate 210 through the assembly groove 211.

[0057] The air pump 100 has circular air inlets 110 and air outlets 120 on its upper left and right sides. The air pump 100 blows air to or draws air from the outside of the air pump 100 through the air inlets 110 and air outlets 120. The blocking part 130 is located inside the air inlets 110 and air outlets 120. Each blocking part 130 includes three rectangular connecting plates 131 and one conical contact part 132. The rectangular connecting plates 131 are evenly distributed in the air inlets 110 and air outlets 120. One end of the rectangular connecting plate 131 is connected to the inner wall of the air inlets 110 and air outlets 120, and the other end is connected to the conical contact part 132. The conical contact part 132 is located at the center of the air inlets 110 and air outlets 120.

[0058] The air blowing valve head 1000 and air suction valve head 2000, corresponding to the air blowing port 110 and air suction port 120, have the same structure. Both the air blowing valve head 1000 and the air suction valve head 2000 include a mounting part 1100, a spring 1200, a rubber plug 1300, and an air stop plug 1400. Alternatively, the air blowing valve head 1000 and / or the air suction valve head 2000 can be replaced with a one-way valve. The air blowing port 110, air suction port 120, blocking part 130, valve head, air blowing hole 410, and air suction hole 420 are all located at the same horizontal height.

[0059] The mounting section 1100 includes a sixth positioning post 1110, a trapezoidal connecting plate 1120, and an assembly cylinder 1130, which are integrally formed. The sixth positioning post 1110 is cylindrical and is horizontally positioned on both sides of the assembly cylinder 1130. The assembly cylinder 1130 is cylindrical and horizontally positioned. The centers of the sixth positioning post 1110 and the assembly cylinder 1130 are located on the same horizontal plane. Two trapezoidal connecting plates 1120 are horizontally arranged between the sixth positioning post 1110 and the assembly cylinder 1130 to fix the sixth positioning post 1110 and the assembly cylinder 1130 together. The sixth positioning post 1110 has a sixth assembly through hole in its center. The outer surface of the housing 400 has a seventh positioning post 540 corresponding to the sixth positioning post 1110. The seventh positioning post 540 has a seventh assembly hole in its center and can be inserted into the sixth assembly through hole. The sixth positioning post 1110 and the seventh positioning post 540 are then fixedly assembled by screws, thereby fixing the valve head mounting part 1100 to the housing 400. The assembly cylinder 1130 is also provided with a partition cylinder 1131, which is also cylindrical. The diameter of the partition cylinder 1131 is smaller than that of the assembly cylinder 1130, and the partition cylinder 1131 and the assembly cylinder 1130 are concentrically arranged. The partition cylinder 1131 and the assembly cylinder 1130 are integrally formed at the end away from the air stopper 1400 to form a circular limiting surface 1140. The spring 1200 is horizontally arranged, and the part of the spring 1200 near the mounting part 1100 is located in the space between the outer wall of the partition cylinder 1131 and the inner wall of the assembly cylinder 1130 and abuts against the circular limiting surface 1140. The air stopper 1400 includes an air stopper disc 1410, and the end of the spring 1200 near the housing 400 abuts against the air stopper disc 1410.

[0060] The airlock 1400 includes an airlock disc 1410, an abutment shaft 1420, and an assembly shaft 1430, all three being integrally formed. Both the abutment shaft 1420 and the assembly shaft 1430 are cylindrical and horizontally connected. The abutment shaft 1420 is located at the end of the airlock 1400 near the blocking portion 130, and the assembly shaft 1430 is located at the end of the airlock 1400 near the mounting portion 1100. The diameter of the abutment shaft 1420 matches the diameter of the conical abutment portion 132. The diameter of the assembly shaft 1430 matches the inner diameter of the partition cylinder 1131, allowing the assembly shaft 1430 to enter the partition cylinder 1131. An air-blocking disc 1410 is located at the connection between the contact shaft 1420 and the assembly shaft 1430. The air-blocking disc 1410 is circular, and its shape matches the shapes of the suction port 420 and the blowing port 410. The diameter of the air-blocking disc 1410 is larger than the diameters of the suction port 420 and the blowing port 410. The rubber plug 1300 has the same shape and size as the air-blocking disc 1410. The rubber plug 1300 and the air-blocking disc 1410 are close together, with the rubber plug 1300 located on the side of the air-blocking disc 1410 closest to the contact shaft 1420. The air-blocking disc 1410 and the rubber plug 1300 are used to seal the suction port 120 and the blowing port 110. In actual operation, when it is necessary to inflate an inflatable product, the air pump 100 moves along the lead screw 200 toward the air inlet 410. The conical contact part 132 in the blocking part 130 at the air inlet 110 comes into contact with the contact shaft 1420 in the air valve head 1000, and pushes the contact shaft 1420 horizontally away from the air inlet 410. This causes the air-blocking plate 1410 and the rubber plug 1300 connected to the contact shaft 1420 in the air valve head 1000 to move away from the air inlet 410 until the air inlet 110 is in contact with the air valve head 1000. When the first limiting surface 532 in the sleeve 530 abuts, the air pump 100 stops moving. Then, air is injected into the inflatable product through the air inlet 110 and the air hole 410. After inflation is completed, the air pump 100 leaves the air hole 410, and the spring 1200 in the air valve head 1000 pushes the air blocking plate 1410 and the rubber plug 1300 back to the air hole 410. The air blocking plate 1410 and the rubber plug 1300 then block the air hole 410. The principle of extracting gas from the inflatable product is the same as that of inflating the inflatable product.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
