Description

Internal and external air pump device and inflatable product

Technical Field

The present disclosure relates to air pump technology, and more particularly, to an internal and external air pump device and an inflatable product.

Background

With the rise of outdoor activities, inflatable products are widely used, such as inflatable beds, inflatable tents, inflatable swimming pools, inflatable sofas, inflatable boats and the like, and in order to meet the requirement of inflating different inflatable products and achieve the effect of time and labor saving, an internal air pump, an external air pump and an internal and external multipurpose air pump are mainly developed in the market at present.

The internal and external multipurpose air pump is particularly widely applied to inflatable products such as air beds with larger volumes. Such air pumps typically have a housing with an air pump built into the inflatable article such as an air bed. The shell is provided with a shell cover, the inner peripheral wall of the shell is provided with an air outlet, and the shell cover is sealed. The air pump main body is arranged in the shell, and the shell cover needs to be opened when the air pump main body charges and discharges the inflatable product so as to be communicated with an external air source (such as air). When a plurality of inflatable products need to be inflated and deflated simultaneously, the pump main body can be independently taken out and matched with a proper air tap to work, so that the function of the external air pump is realized, and the use is convenient. However, the cover with such a structure generally has the function of secondary sealing of the inflatable product, and if the cover is damaged, the inflatable product is at risk of air leakage in the use process, so that the user experience is affected.

Therefore, how to design an internal and external air pump device with reliable structure is a technical problem to be solved in the industry.

At present, common internal and external air pump products are arranged in a shell formed in an inflatable product and are secondarily sealed through a shell cover. However, the cover of this structure generally has the function of secondary sealing of the inflatable product, and if the cover is damaged, the inflatable product will have a risk of air leakage during use, thereby affecting the user experience.

In view of this, an internal and external air pump device may be provided in the embodiments of the present disclosure, solving the above problems.

As shown in fig. 1A to 1C, the overall structure of the internal and external air pump device in the embodiment of the present disclosure is shown.

Fig. 1A shows a schematic diagram of a combined structure of an internal and external air pump device in an embodiment of the present disclosure.

As shown in fig. 1A, the internal and external air pump device 1 includes a pump housing 10, a pump body 11, a cover plate 12, and the like. As shown in fig. 1B, a schematic diagram of the structure in fig. 1A is shown in which the pump body 11 is separated from the pump casing 10 and the cover plate 12 is in a closed state. Fig. 1C shows a schematic configuration in fig. 1A in which the pump body 11 is disengaged from the pump casing 10 and the cover plate 12 is in an open state.

In fig. 1B, the pump case 10 has an open end, an accommodation space 101 communicating with the open end, and a first ventilation portion 102 communicating with the accommodation space 101 and an air chamber of an inflatable article (not shown). The pump body 11 is detachably provided in the accommodating space 101. Illustratively, the open end is shown in fig. 1 as the upper end of the pump casing 10, the first venting portion 102 may be provided on one side of the pump casing 10, and the first venting portion 102 may be a through hole or a through hole. Illustratively, the accommodation space 101 and the pump body 11 are present as rectangular bodies of uniform shape. The accommodating space 101 may extend along a first direction, which may be a rectangular parallelepiped direction, and a side surface provided with the first ventilation portion 102 is located at one end portion in the first direction. Illustratively, each wall of the receiving space 101 limits movement of the pump body 11 in a direction other than the first direction. As shown in fig. 1A to 1C, the width of the rectangular body-shaped accommodation space 101 matches the width of the pump body 11, and the length of the accommodation space 101 is greater than the length of the pump body 11. After the pump body 11 is placed in the accommodating space 101, the second end portion thereof abuts against the side of the pump case 10 where the first ventilation portion 102 is provided. The two side surfaces of the pump body 11 adjacent to the second end portion respectively abut against the two side wall surfaces of the accommodating space 101 in the width direction, thereby realizing the limit of the pump body 11 in the three directions. Since the length of the pump body 11 is shorter than the length of the accommodating space 101, a free portion is formed between the first end portion thereof and the opposite side wall of the accommodating space 101 away from the first vent portion 102, the free portion is defined by a wall surface where the second end portion of the pump body 11 and the pump housing 10 meet, a vent chamber 1011 is defined, and the vent chamber 1011 is defined at the second vent portion 103 of the open end.

As shown in fig. 1B and 1C, a state in which the pump body 11 is detached from the accommodation space 101 can be illustrated. The pump body 11 has an air inlet 111 and an air outlet 112, the air outlet 112 being shown in fig. 1A to 1C, and the air inlet 111 may be shown with reference to fig. 3B. Illustratively, the air outlet 112 and the air inlet 111 of the pump body 11 may be located at opposite ends thereof, i.e., a first end and a second end. Illustratively, the pump body 11 may have a pump body 11 housing, and a pump chamber communicating the suction port 111 and the discharge port 112 may be formed therein.

The pump body 11 can be flexibly provided in the accommodating space 101 by different postures to realize the charge/discharge function. As illustrated in fig. 1A to 1C, the pump body 11 is disposed in the accommodating space 101 such that the second end portion is abutted against the side of the first ventilation portion 102, and the suction port 111 can be in sealing communication with the first ventilation portion 102. Accordingly, the air inlet 111 communicates with the ventilation chamber 1011 and communicates with the second ventilation portion 103. In this state, the inflation of the inflatable article is achieved, and the inlet port 111 sucks air from the inflatable article through the first ventilation portion 102 and sends out air from the second ventilation portion 103 through the air outlet port 112. In another example, the pump body 11 may be turned to be disposed in the accommodating space 101, so that the first end portion where the air outlet 112 is located is abutted against the side where the first ventilation portion 102 is located, and the air outlet 112 is in sealing communication with the first ventilation portion 102. Accordingly, the air inlet 111 communicates with the ventilation chamber 1011 and communicates with the second ventilation portion 103. In this state, the inflatable article is inflated, and the air inlet 111 sucks air from the outside through the second air passage 103 and inflates the inflatable article from the first air passage 102 through the air outlet 112. Illustratively, a seal may be provided at the first venting portion 102; and/or, the air inlet 111 and the air outlet 112 may be provided with sealing elements to realize close connection with the first ventilation part 102, so as to ensure air tightness during inflation and deflation.

The cover plate 12 is movably connected with the pump housing 10. Illustratively, the cover plate 12 may be hinged to the pump housing 10. For example, in fig. 1A to 1C, one end of the cover plate 12 is hinged to the other side of the corresponding second end portion of the pump case 10 so as to be rotatable to bring the opposite end of the cover plate 12 closer to or farther from the second end portion of the pump body 11, while closing or opening the vent chamber. Illustratively, the hinge is shown in FIG. 2A, wherein the shafts 126 on opposite sides of the cover plate 12 rotatably engage the shaft holes in the inner wall of the pump housing 10. Illustratively, the cover 12 is provided with a plurality of vent holes 121 communicating with the vent chamber 1011 and the outside, and the vent holes 121 may be provided in an array or other configuration, for example. In fig. 1A and 1B, the cover 12 is in a closed state, or as shown in fig. 1C, the cover 12 is rotated to an open state.

For positioning the pump body 11, a locking structure may be provided between the pump body 11 and the cover plate 12. Since the pump body 11 may be disposed in the accommodating space 101 in two positions corresponding to the first vent hole in the air inlet 111 or the air outlet 112, the first engaging portion 113 may be disposed at a first end portion of the pump body 11 where the air outlet 112 is disposed and at a second end portion of the air inlet 111. Correspondingly, a second engaging portion 122 may be disposed at an end of the cover 12 facing the pump body 11, for engaging with a first engaging portion 113 of the pump body 11 in the closed state. As an example, the first engaging portion 113 and the second engaging portion 122 may have a structure in which the hook 131 and the notch are engaged. For example, the first engaging portion 113 is a recess, and the second engaging portion 122 is a tongue. In fig. 1C, the cover plate 12 is rotated to be in an opened state, and the pump body 11 can be taken out of or put into the accommodating space 101; as shown in fig. 1A, the cover 12 is in a closed state, and the second engaging portion 122 is engaged with the first engaging portion 113. Since the side surface of the pump body 11 other than the end where the engagement is formed is surrounded by the inner wall of the accommodating space 101 to limit the movement of the pump body 11 in the direction other than the first direction, the movement of the pump body 11 in the first direction is limited by the engagement of the second engagement portion 122 with the first engagement portion 113, so that the pump body 11 is positioned in the accommodating space 101.

As shown in fig. 2A and 2B, the structure of the cover plate 12 in the embodiment of the present disclosure is shown. As shown in fig. 2B, the cover 12 forms a guiding cavity 123, and the engaging member 13 and the first elastic member 14 may be disposed in the guiding cavity 123. A schematic structural view of the engagement member 13 and the first elastic member 14 mounted in the guide cavity 123 is shown in fig. 2A. Fig. 2B shows a schematic structure of the engaging member 13 disengaged from the guiding cavity 123.

Illustratively, the cover 12 is shown with a frame 124 protruding from the surface thereof, and a gap exists between the frame 124 and the cover 12, thereby forming the guide cavity 123. The extending direction of the guide cavity 123 may be a far and near direction with respect to the position of the pump body in the accommodation space 101. The guide cavity 123 is movably provided with an abutting engagement member 13 and a first elastic member 14, and the first elastic member 14 maintains the movement trend of the engagement member 13 to the outside of the guide cavity 123. For convenience in description of the structure of the guide chamber 123 and the positioning member. In fig. 2B, the frame 124 has a groove 1241 formed at an inner end thereof, the width of the groove 1241 is adapted to the width of the first elastic member 14, the first elastic member 14 is disposed in the groove 1241, and the extending direction of the first elastic member 14 is consistent with the guiding cavity 123.

Illustratively, the catch 13 includes a first portion slidably disposed within the guide cavity 123 and a second portion coupled to the first portion that extends out of the guide cavity 123. The second engaging portion 122 may be provided on the second portion, for example, may be provided at an outer end of the second portion. A blocking structure may be formed between the engaging member 13 and the cover 12 to limit the engaging member 13 from being separated from the guiding cavity 123. In the illustrated example, the first portion of the engaging member 13 may include a pair of hooks 131 disposed opposite to each other, the rear end of the guiding cavity 123 is provided with penetrating openings 1231 corresponding to the two hooks 131, so that the two hooks 131 are elastically deformed by being pressed by the inner walls of the two sides of the guiding cavity 123 during entering the guiding cavity 123, and the two hooks 131 pop out after penetrating the penetrating openings, so that the hook portions are hooked on the end walls of the two sides to limit the engaging member 13 from being separated from the guiding cavity 123.

Illustratively, the first elastic member 14 may be a spring or other elastic body, and may be sleeved on the first portion, and two ends of the first elastic member respectively abut against between the engaging member 13 and the frame 124, so as to maintain the outward spring tendency of the second engaging portion 122. When the cover 12 is closed, the second engaging portion 122 can be displaced toward the guide cavity 123 by an external force, and the second engaging portion 122 is ejected to engage with the first engaging portion 113 by the restoring force of the first elastic member 14 when the cover 12 is closed.

In view of stability in positioning the pump body 11, other engagement structures may be provided in addition to the engagement structures in which the first engagement portion 113 and the second engagement portion 122 are engaged. The other engagement structure may be between the cover plate 12 and the pump casing 10, or may be between the pump casing 10 and the pump body 11. For example, referring to fig. 1C and fig. 2A, the cover 12 is further provided with at least one fourth engaging portion 125. The pump housing 10 is provided with at least one third engaging portion 104 engaged with at least one fourth engaging portion 125 of the cover plate 12 in the closed state. When the engagement between the first engaging portion 113 and the second engaging portion 122 fails, any engagement between the fourth engaging portion 125 and the third engaging portion 104 is still effective, and the function of the cover plate 12 in the present utility model is not affected. Thereby, a stable sealing connection can be maintained between the pump body 11 and the first vent portion 102 of the pump casing 10.

In the illustrated example, the third engaging portions 104 are provided in a pair, and are provided on opposite wall surfaces of the accommodating space 101; the opposite sides of the cover plate 12 are respectively provided with fourth engaging portions 125 which are engaged with each of the third engaging portions 104 in a one-to-one correspondence. The third engaging portion 104 may be a notch, and the fourth engaging portion 125 may be a hook portion extending from the cover 12 into the pump housing 10 to be hooked in the notch. Alternatively, in other embodiments, the implementation structures (notch and hook) of the third engaging portion 104 and the fourth engaging portion 125 may be interchanged, which is not limited to the illustration.

Illustratively, as shown in FIG. 1B, the first venting portion 102 is provided with a valve assembly 15. The specific structure of the valve assembly is described below with reference to fig. 3A to 3C.

Fig. 3A shows a schematic view of a valve assembly with a pump housing removed in an embodiment of the disclosure.

The valve assembly 15 includes a valve spool 151. The valve body 151 is movable in a near-far direction with respect to the first ventilation portion 102. The spool 151 includes a check valve plate 1511, and a spool support 1512 extending toward the accommodation space. Illustratively, the valve assembly 15 further includes a protective housing 152 covering the first venting portion 102, and the valve core 151 is disposed between the protective housing 152 and the second venting portion 103. The protecting cover 152 has a hollow structure for ventilation. When the internal and external air pump device 1 is internally arranged in an inflatable product, the air cavity of the inflatable product is arranged outside the protective cover 152, and the protective cover 152 can protect the valve core 151 from being collided by the inflatable product.

Illustratively, the spool 151 may include a check valve plate 1511 and a spool support 1512 that are detachable from each other, one end of the spool support 1512 forming a valve cover 15121 that receives the check valve plate 1511. One side surface (such as a side surface facing away from the first ventilation portion 102) of the valve cover 15121 is provided for fitting the check valve plate 1511, and the check valve plate 1511 may be exemplified by an elastically deformable material, such as rubber. The other side of the valve cover 15121 (e.g., the side facing the first venting portion 102) may move with the valve core 151 to close the second venting portion 103. Alternatively, the valve cover 15121 forms a gap with the second vent portion 103 in response to the movement of the valve body 151, thereby conducting the second vent portion 103. Illustratively, the valve cover 15121 and the check valve plate 1511 may have a shape of a disk adapted to the shape of the disk. The valve cover 15121 is connected with an extension part extending toward the pump case 10, and the extension part comprises a valve core push rod 15122 and supporting blocks 15123 fixedly connected to both sides of the valve core push rod 15122 and the valve cover 15121. For example, referring to fig. 3C together, the valve cover 15121 may have a positioning hole 15124 at a position corresponding to the valve core mandrel 15122, and the check valve 1511 may have a positioning post 15111 penetrating the positioning hole 15124.

Illustratively, the first venting portion 102 may be defined by a cylindrical tubular body portion protruding from the surface of the pump housing 10. Therefore, the pipe diameter of the pipe body can be designed according to the size of the ventilation part. The space inside the tube may be provided with a limit or a part or all of the structure for driving the valve element 151.

To enable smooth and limited movement of the valve assembly 15 in one stable direction, the first venting portion 102 may be provided with a limiting through hole 161, as shown in fig. 3A, for example, the limiting through hole 161 being configured to allow the spool jack 15122 to pass therethrough, thereby limiting the direction of movement of the spool jack 15122. Further example, the pump housing 10 is provided with a second ventilation bracket 16 with a hollow out at the first ventilation portion 102, the second ventilation bracket 16 is provided with a limiting through hole 161 for the pressed portion to pass through, and the limiting through hole 161 limits the direction of the movement of the pressed portion. Further, as an example, the limiting through hole 161 is identical to the cross-sectional shape of the spool jack 15122 and the support blocks 15123 on both sides, so that the rotation of the spool jack 15122 is also limited by being coupled to the spool jack 15122 and the two support blocks 15123. It should be noted that the spool jack 15122 may be cylindrical; the structure that the two supporting blocks 15123 are connected with the valve core ejector 15122 is beneficial to strengthening the strength of the valve core ejector 15122, forming a gap between the valve core ejector 15122 and a valve cover, destroying the circular cross section shape of the valve core ejector 15122, and being capable of matching with the limiting through hole 161, and having the functions of guiding and limiting the rotation of the valve core ejector 15122.

In addition, as shown in fig. 3A, for example, the spool top rod 15122 may have a gap with respect to the valve cover 15121 for accommodating the positioning post 15111 passing through the positioning hole 15124, and an end of the positioning post 15111 facing the positioning post 15111 may be perforated for receiving the positioning post 15111. At least one protruding clamping portion 15112 is protruding on the side surface of the positioning column 15111, a clamping groove is formed between the protruding clamping portion 15112 and the unidirectional valve plate 1511 or other protruding portions (such as another protruding clamping portion 15112) on the positioning column 15111, and the protruding clamping portion 15112 may have a frustum shape with a smaller area and one end facing the pump casing 10. The gradual change inclined surface of the circumferential side surface of the protruding clamping portion 15112 can facilitate the protruding clamping portion 15112 to be extruded into the positioning hole 15124 along with the movement of the positioning column 15111 into the positioning hole 15124, and can be elastically deformed (based on the elastic deformation material of the unidirectional valve plate 1511) so that the protruding clamping portion 15112 passes through the positioning hole 15124 to enable the peripheral portion of the positioning hole 15124 to be clamped in the clamping groove, so that the unidirectional valve plate 1511 is positioned and attached to the valve cover 15121.

The valve cover 15121 may be closed on the first venting portion 102 to close the first venting portion 102 in a non-inflated and deflated state. Illustratively, there are two ways to make the first venting portion 102 conductive to achieve inflation and deflation, respectively.

One way is to push the check valve plate 1511 to deform by air flow, and fig. 3A shows that the check valve plate 1511 deforms in an inflated state, and the first ventilation part 102 is conducted through the hollowed part on the valve cover 15121. The principle of the check valve sheet 1511 is explained. The check valve 1511 is made of deformable material such as rubber. The deformation of the pump casing 10 is blocked by the spool jack 15122, and therefore the deformation of the pump casing 10 is only possible. That is, in the structure illustrated in the drawing, the valve sheet is deformed and turned on only when the second ventilation portion 103 transmits the air flow to the first ventilation portion 102, that is, turned on when the inflatable article to which the first ventilation portion 102 communicates is inflated. Of course, it will be appreciated that if the check valve 1511 is disposed on the side of the valve cover 15121 facing the interior of the pump case 10, the check valve 1511 will be turned on when deflated and turned off when inflated.

Alternatively, the valve body 151 is pushed out of the first ventilation portion 102, so that a gap exists between the valve cover 15121 and the first ventilation portion 102, and the gap allows the first ventilation portion 102 to be in conduction. The two conduction modes can respectively correspond to the inflation or deflation states of the device.

As shown in fig. 3B, a simplified schematic structure of the pump body 11 in which a pressing portion is formed to be engaged with a pressed portion of the valve body 151 in the embodiment of the present disclosure is shown.

In fig. 3B, a first end portion of the pump body 11 where the suction port 111 is located is provided with a pressing portion that mates with the pressure receiving portion. Further exemplary, the pump body 11 is provided with a first ventilation support 17 having a hollow at the suction port 111, and a portion of the first ventilation support 17 serves as the pressing portion. In fig. 3B, the middle portion of the first ventilation support 17 is solid, and a ventilation hollow is formed around the middle portion. The pressing portion 171 is exemplified as a middle portion of the first ventilating bracket 17. The pressure receiving portion (i.e., an inward end of the spool jack 15122) is pressed outward by the pressing portion 171 (i.e., a middle portion of the first ventilation bracket 17), and drives the spool 151 away from the first ventilation portion 102, so that the first ventilation portion 102 is conducted.

To enable the spool support 1512 to maintain closure of the first vent 102 at all times without being pushed by external forces to maintain the air cavity of the pneumatic product closed, in some examples, the spool support 1512 may also be provided with a second elastic member 18, as shown in fig. 3C. The second elastic member 18 is limited between the pump casing 10 and the pressure receiving portion, and the second elastic member 18 keeps the valve cover 15121 of the valve body 151 at a position closing the first venting portion 102 to block the first venting portion 102. The second elastic member 18 may be, for example, a spring. The spool jack 15122 is provided at one end facing the inside of the pump casing 10 to extend from the first vent 102 into the pump casing 10, and the spool jack 15122 may be inserted into the pump casing 10 through the restricting orifice 161, as an example. The portion of the valve core push rod 15122 in the pump casing 10 may be provided with a resisting portion, which may be specifically exemplified by a column sleeve 19 that is sleeved on one end of the valve core push rod 15122 in the pump casing 10. The second elastic member 18 is sleeved on the portion of the spool push rod 15122 in the pump casing 10, one end of the second elastic member abuts against the resisting portion, and the other end of the second elastic member abuts against the inner wall of the pump casing 10 (may be an edge portion of one end of the limiting through hole 161 in the pump casing 10). The length of the second resilient member 18 may be configured to maintain the valve cover 15121 against the pump housing 10 in an undeformed state to maintain the seal of the first vent 102. When the valve core 151 is pressed to move outside the first ventilation part 102, the second elastic member 18 is compressively deformed; after that, when the pump body 11 is taken out, the second elastic member 18 is deformed and restored to restore the valve body 151. For a clearer view of the first elastic member 14 and the second elastic member 18, reference may also be made to the configuration cut away in fig. 4 and 5.

In addition, in some examples, as shown in fig. 3C, the bottom wall of the accommodating space 101 is provided with a support rib 105 for supporting the pump body, and the pump body 11 and the bottom wall form a ventilation gap. On the one hand, support for the pump body can be formed, and on the other hand, heat dissipation of the pump body is facilitated.

Please refer to fig. 4 and 5 again. A schematic cross-sectional view of the internal and external air pump device 1 in the inflated state in the embodiment of the present disclosure is shown in fig. 4. A schematic cross-sectional view of the internal and external air pump device 1 in the deflated state in the embodiment of the present disclosure is shown in fig. 5.

As can be seen from fig. 4, the conduction of the first ventilation part 102 is controlled by the valve plate in this state. When the pump body 11 is operated, as indicated by an arrow a in the drawing, air is taken in from the second ventilation portion 103 and passes through the air passage in the pump body 11 from the air inlet 112, and is output from the air outlet 111 to reach the first ventilation portion 102. The air flow hits the check valve sheet 1511 to deform (deformation is exemplarily shown in the figure, but deformation is conceivable) so as to conduct the first ventilation portion 102, and the air flow is inflated from the first ventilation portion 102 into the air chamber of the air-filled article.

As can be seen from fig. 5, in this state, the first ventilation portion 102 is brought into conduction by the gap generated by the movement of the spool 151 away from the first ventilation portion 102. When the pump body 11 is operated, as shown by an arrow B in the drawing, the suction port 111 of the pump body 11 is taken in from the air chamber of the air-filled article and passes through the air passage in the pump body 11 to be output at the air outlet port 111 to reach the second ventilation portion 103 and be discharged.

For example, as shown in fig. 4 and 5, the ventilation chamber 1011 may also have a storage function. For example, there is a storage space available for accommodating a power cord or air tap. In fig. 4 and 5, an air tap 2 is exemplarily shown in the storage space. In fig. 1B, the pump body 11 is taken out of the pump case 10, and the air outlet 112 of the pump body 11 may have a connection structure for connecting an air tap, and the connection structure may be, for example, a rotation engagement structure, a telescopic engagement structure, or the like.

Referring to fig. 1B and 6, a schematic structural view of a pump body 11 in an embodiment of the present disclosure may be shown. Fig. 6 shows an exploded structural schematic view of the pump body 11 in the embodiment of the present disclosure.

As shown in fig. 1B, the pump body 11 is an electric control device, and a function key 117 for controlling the operation thereof is provided at the top. The function keys 117 include types such as a switch, a pause, and the like. As an example, the surface (which may be the top) of the pump body 11 may also be provided with a handle 118 to facilitate removal of the pump body 11 from the pump housing.

As further shown in fig. 6, the pump body 11 includes a pump body housing including a pump chamber housing 114 and first and second end caps 115 and 116 at both ends. The first end cap 115 is provided with the air outlet 112, and the second end cap 116 is provided with the air inlet 111. The pump housing 114 forms a pump chamber 1141 with two ends penetrating, and the pump chamber 1141 is disposed along an extending direction. The pump chamber 1141 may be provided with a motor 3, a fan 4, a control circuit board 5, a battery 6, etc., and may be sleeved on the driving fan 4 to rotate to form a negative pressure, so as to generate an airflow from the air inlet 111 to the air outlet 112. The control circuit board 5 is electrically connected with and controls the motor 3. The battery 6 is used for supplying power to the control circuit board 5 and the motor 3. The control circuit board 5 may be positioned corresponding to the function key 117 to operate the corresponding function according to a trigger signal generated by pressing the function key 117. Other structural components that are functionally relatively minor, such as the first venting bracket, the second venting bracket, and other mounting sockets, are not specifically described herein.

The principle of use of the internal and external air pump device 1 in the embodiments of the present disclosure is reviewed in conjunction with the previous figures.

When the built-in air-filled article is to be inflated, the air outlet 112 of the pump body 11 is placed in alignment with the end of the valve assembly 15 of the pump casing 10. Then, the second engaging portion 122 on the cover 12 is locked, and the first engaging portion 113 of the pump body 11 is aligned to the first engaging portion 13 of the pump body 11 to be abutted, and then the hand is released, and the engaging member 13 can be locked to the corresponding first engaging portion 113 of the pump body 11 due to the action of the first elastic member 14. Further, the switch function key on the surface of the pump body 11 is pressed, the fan 4 of the motor 3 starts to operate, and the outside air enters the ventilation chamber 1011 through the second ventilation portion 103 on the cover plate 12 and enters from the air inlet 111 of the pump body 11, and then blows out the valve sheet of the valve assembly 15 through the air outlet 112 of the pump body 11 to enter the air-filled article. When the inflation is completed, a pause function key can be pressed to stop the inflation.

When the built-in inflatable product needs to be deflated, the air suction port 111 of the pump main body 11 is aligned with one end of the valve assembly 15 of the pump shell 10 and then is placed, and the first ventilation bracket 17 at the air suction port 111 of the pump main body 11 pushes the valve core ejector rod 15122 of the shell valve to drive the valve core 151 to open so as to generate a ventilated gap. By locking the pump body 11 and the pump casing 10 by the snap-on cover 12, the motor 3 drives the fan 4 to start operating by pressing the switch function key, and the air inside the air-filled product enters the pump body 11 through the gap and through the air inlet 111, flows through the ventilation chamber 1011 through the air outlet 112, and is discharged from the air inlet and outlet 112 of the cover 12. When the deflation is completed, a switch function key can be pressed to stop the deflation.

When other inflatable products need to be inflated, the second clamping part 122 is buckled to be separated from the first clamping part 113, the cover plate 12 is rotated to be opened, the pump body 11 is taken out of the pump shell 10, the air outlet 112 and the air inlet of the pump body 11 can be matched with the air tap to perform inflation/deflation work, and after the inflation/deflation work is completed, the air tap, the power line and the like can be received into the ventilation cavity 1011.
