[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a built-in lithium battery charging and suction dual-purpose air pump, including a protective component 1, a charging and suction component 2 is provided in the inner cavity of the protective component 1, an air intake 3 is provided on one side wall of the protective component 1, one end of the air intake 3 is connected to the air inlet end of the charging and suction component 2; a hollow cover 4 is provided on the outer wall of the protective component 1 and outside the air intake 3.

[0026] The protective component 1 not only allows for the installation and protection of the inflation / suction component 2, but also facilitates the installation of the air intake nozzle 3 and the perforated cover 4. When inflating equipment such as air mattresses, inflatable bathtubs, and inflatable swimming pools, first connect the air inlet of the external equipment to the air outlet of the inflation / suction component 2. Then, by turning on the inflation / suction component 2, outside air is drawn into the component through the air intake nozzle 3 and the perforated cover 4. The drawn-in air is then pressurized and discharged to inflate the external equipment. When deflation or venting of the external equipment is required, the user can first remove the perforated cover 4, then connect the air intake nozzle 3 to the air inlet of the external equipment. Next, by turning on the inflation / suction component 2, the component can draw out and discharge the gas from the external equipment, thus enabling rapid deflation or venting. The overall dual-purpose inflation / suction air pump has a compact structure and meets both flushing and rinsing functions, improving the functionality and convenience of the equipment.

[0027] See Figure 2 , Figure 3The protective component 1 includes a protective shell 11. A vent 12 is provided on one side of the outer wall of the protective shell 11. A bracket 13 for engaging the suction nozzle 3 is provided in the inner cavity of the vent 12. Limiting strips 14 are provided on both sides of the inner cavity of the protective shell 11 at the middle position. A slot 15 for engaging the charging and suction component 2 is provided on both sides of the inner cavity of the protective shell 11 above the two limiting strips 14. A protective cover 16 is provided on one side of the top of the protective shell 11. A movable seat 17 for installing the protective cover 16 is provided on one side of the top surface of the protective shell 11. A locking claw 19 is provided on the other side of the top surface of the protective shell 11. A locking groove 18 for engaging the locking claw 19 is provided on one side of the protective cover 16. A protective ring 110 is provided at the top of the outer wall of the protective shell 11.

[0028] The protective shell 11 in the protective assembly 1 provides a base for placing the filling and suction assembly 2 and provides space for the air duct 12. Since the inner cavity of the air duct 12 is equipped with a bracket 13 for engaging the suction nozzle 3, the suction nozzle 3 can be engaged and installed, thereby improving the stability of the suction nozzle 3 in use. The limiting strip 14 and the slot 15 limit the engagement of the filling and suction assembly 2, thereby improving the stability of the filling and suction assembly 2 installed inside the protective shell 11. The protective cover 16 allows it to be mounted on the top surface of the protective shell 11 via the movable seat 17. On one side, it can be flexibly rotated and closed under the action of the movable seat 17. Then, through the locking claw 19, it can engage and limit the locking groove 18 on the locking claw 19, thereby preventing the protective cover 16 from opening automatically after closing. When it is necessary to open the protective cover 16, just press one side of the locking claw 19, thereby releasing the locking claw 19 from engaging and limiting the locking groove 18, so that the user can easily rotate and open the protective cover 16. Since the protective ring 110 is provided at the top of the outer wall of the protective shell 11, it can protect the protective shell 11, thereby improving the service life of the protective shell 11.

[0029] See Figures 2-4 The charging assembly 2 includes a bottom shell 21, a sleeve 22 at the top of the bottom shell 21, a top shell 23 at the top of the sleeve 22, an air duct 24 on the side wall of the sleeve 22, a micro air pump 25 in the inner cavity of the sleeve 22, and an air inlet end of the micro air pump 25 connected to one end of the air duct 24; a through hole 26 on one side of the top surface of the top shell 23, an air nozzle 27 in the inner cavity of the through hole 26, and an air outlet end of the air nozzle 27 connected to the air outlet end of the micro air pump 25; a control board 28 and a lithium battery 29 on the bottom surface of the inner cavity of the bottom shell 21; locking tongues for engaging the slot 15 on both sides of the top shell 23; a control switch 210 on one side of the top surface of the top shell 23, a charging port 211 on one side of the control switch 210; and multiple heat dissipation holes 212 on the other side of the sleeve 22.

[0030] The housing 22 in the inflation assembly 2 can be combined with the bottom housing 21 and the top housing 23 to form a closed space, provide an installation base for the air duct 24, and also install and fix the miniature air pump 25. Since the air inlet of the miniature air pump 25 is connected to one end of the air duct 24, and the through hole 26 on the top surface of the top housing 23 is provided with an inflation nozzle 27, and the bottom end of the inflation nozzle 27 is connected to the air outlet of the miniature air pump 25, when it is necessary to inflate the external device, the air inlet of the external device can be connected to the air outlet of the inflation nozzle 27 first, and then the control switch 210 can be used to open the control panel 28. When the miniature air pump 25 is in operation, it draws in outside air through the air guide tube 24, pressurizes the air, and delivers it to the inflation nozzle 27 for inflation of external equipment. When it is necessary to deflate or release air from external equipment, the user can first remove the perforated cover 4, then connect the air intake nozzle 3 to the air inlet of the external equipment, and then turn on the miniature air pump 25 via the control switch 210 and the control board 28. This allows the miniature air pump 25 to draw out the gas from the external equipment through the air guide tube 24 and then release it, thereby enabling rapid deflation or release of air from the external equipment.

[0031] During operation, the protective component 1 not only installs and protects the inflation and suction component 2, but also allows for the installation of the air intake nozzle 3 and the perforated cover 4. When inflating equipment such as air mattresses, inflatable bathtubs, and inflatable swimming pools, first connect the air inlet of the external equipment to the air outlet of the inflation and suction component 2. Then, by turning on the inflation and suction component 2, outside air is drawn into the inflation and suction component 2 through the air intake nozzle 3 and the perforated cover 4. The drawn-in air is then pressurized and discharged, thus inflating the external equipment. When deflation or venting of the external equipment is required, the user can first remove the perforated cover 4, then connect the air intake nozzle 3 to the air inlet of the external equipment. Next, by turning on the inflation and suction component 2, the gas inside the external equipment is drawn out and discharged, thus achieving the purpose of quickly deflation or venting of the external equipment. The overall inflation and suction dual-purpose air pump has a compact structure and meets the dual-purpose function of rinsing, improving the functionality and convenience of the equipment.

[0032] The protective shell 11 in the protective assembly 1 provides a base for placing the filling and suction assembly 2 and provides space for the air duct 12. Since the inner cavity of the air duct 12 is equipped with a bracket 13 for engaging the suction nozzle 3, the suction nozzle 3 can be engaged and installed, thereby improving the stability of the suction nozzle 3 in use. The limiting strip 14 and the slot 15 limit the engagement of the filling and suction assembly 2, thereby improving the stability of the filling and suction assembly 2 installed inside the protective shell 11. The protective cover 16 allows it to be mounted on the top surface of the protective shell 11 via the movable seat 17. On one side, it can be flexibly rotated and closed under the action of the movable seat 17. Then, through the locking claw 19, it can engage and limit the locking groove 18 on the locking claw 19, thereby preventing the protective cover 16 from opening automatically after closing. When it is necessary to open the protective cover 16, just press one side of the locking claw 19, thereby releasing the locking claw 19 from engaging and limiting the locking groove 18, so that the user can easily rotate and open the protective cover 16. Since the protective ring 110 is provided at the top of the outer wall of the protective shell 11, it can protect the protective shell 11, thereby improving the service life of the protective shell 11.

[0033] The housing 22 in the inflation assembly 2 can be combined with the bottom housing 21 and the top housing 23 to form a closed space, provide an installation base for the air duct 24, and also install and fix the miniature air pump 25. Since the air inlet of the miniature air pump 25 is connected to one end of the air duct 24, and the through hole 26 on the top surface of the top housing 23 is provided with an inflation nozzle 27, and the bottom end of the inflation nozzle 27 is connected to the air outlet of the miniature air pump 25, when it is necessary to inflate the external device, the air inlet of the external device can be connected to the air outlet of the inflation nozzle 27 first, and then the control switch 210 can be used to open the control panel 28. When the miniature air pump 25 is in operation, it draws in outside air through the air guide tube 24, pressurizes the air, and delivers it to the inflation nozzle 27 for inflation of external equipment. When it is necessary to deflate or release air from external equipment, the user can first remove the perforated cover 4, then connect the air intake nozzle 3 to the air inlet of the external equipment, and then turn on the miniature air pump 25 via the control switch 210 and the control board 28. This allows the miniature air pump 25 to draw out the gas from the external equipment through the air guide tube 24 and then release it, thereby enabling rapid deflation or release of air from the external equipment.

[0034] In summary, the device features a compact overall structure for both filling and suction air pumps, and also fulfills the dual function of rinsing, thus improving the functionality and convenience of the equipment.
