Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] Embodiment 1:

[0037] This embodiment provides an air pump for a medical massager, including a housing 1, and further including:

[0038] A circuit board 2, which is fixedly arranged inside the housing 1 and is used to control the air pump;

[0039] Button holes 3, which have several, and several button holes 3 are all through-opened at the upper end of the housing 1;

[0040] A panel 4, which is fixedly connected to the upper end of the housing 1;

[0041] A spring 5, which is located in the keyhole 3. The lower end of the spring 5 is fixedly connected to the circuit board 2, and the upper end of the spring 5 is in contact connection with the lower surface of the panel 4;

[0042] Among them, the spring 5 is made of metal. The spring 5 is in a compressed state to ensure good contact between the upper end of the spring 5 and the lower surface of the panel 4. And because the force application point of the spring 5 is small, it is not easy to produce fatigue problems.

[0043] In this technical solution, when the circuit needs to be controlled, there are specifically 3 methods:

[0044] 1. By touching the position on the upper end of the panel 4 corresponding to the keyhole 3 with a finger, the bioelectric signal of the finger is transmitted through the panel 4 to the spring 5 in the current keyhole 3, and then transmitted by the spring 5 to the circuit board 2, so that the sensor on the circuit board 2 senses this signal, and thus the controller is controlled to achieve the effect corresponding to the button. In this method, the spring 5 plays the role of transmitting the electric signal.

[0045] 2. A capacitive touch sensor is provided on the circuit board 2 (this is the prior art and will not be elaborated here). When a finger touches the position on the upper end of the panel 4 corresponding to the keyhole 3, it will cause a change in the local capacitance, which can be detected by the capacitive touch sensor on the circuit board 2, thus achieving the control effect. In this method, the spring 5 plays the role of providing mechanical contact or pressure transmission, providing the triggering force or contact.

[0046] 3. A resistive touch sensor is provided on the circuit board 2 (this is the prior art and will not be elaborated here). When a finger touches the position on the upper end of the panel 4 corresponding to the keyhole 3, it will cause a change in the local resistance, and thus the resistive touch sensor detects the touch of the finger by changing the resistance value, thus achieving the control effect. In this method, the spring 5 also plays the role of providing mechanical contact or pressure transmission, providing the triggering force or contact.

[0047] The housing 1 is divided into an upper half 11 and a lower half 12. The upper half 11 and the lower half 12 are connected by buckles, making the assembly more convenient. An inner cavity is formed between the upper half 11 and the lower half 12. The circuit board 2 is located inside the inner cavity. The keyhole 3 is opened on the upper half 11. When overall installation is required, only the lower end of the spring 5 needs to be fixedly arranged at the corresponding position on the circuit board 2, and then the upper half 11 is covered on the lower half 12, so that the upper half 11 and the lower half 12 are buckled and connected. At this time, the spring 5 will be located in the keyhole 3 and protrude slightly from the upper surface of the upper half 11 due to the elastic force. Then, the panel 4 is fixedly arranged on the upper surface of the upper half 11 by adhesion, so that the lower surface of the panel 4 presses a small section of the spring 5 protruding from the upper surface of the upper half 11 into it, and the spring 5 is kept in a compressed state, and the installation is completed, making the overall installation fast.

[0048] In actual tests, compared with the conventional mechanical keys, the settings of the panel 4 and the spring 5 are not only convenient for installation but also not easily damaged. The mechanical keys are exposed on the outside and are easily damaged due to impacts, and the impact force is easily transmitted to the circuit board 2, resulting in damage to the circuit board 2. The panel 4 can play a protective role while ensuring control.

[0049] Through this structural design, by setting the spring 5 in the keyhole 3, it is ensured that when touching the panel 4, it can control the circuit board 2 inside the housing 1. At the same time, the design of the panel 4 is not easily damaged, and the overall installation is also faster, improving economic benefits.

[0050] Embodiment 2:

[0051] This embodiment provides an air pump for a medical massager. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0052] Furthermore, it further includes:

[0053] An installation groove 6 is formed by the upper end of the panel 4 being recessed. The contour of the installation groove 6 matches the contour of the panel 4, and the depth of the installation groove 6 matches the thickness of the panel 4.

[0054] In this technical solution, by setting the installation groove 6, a positioning effect is achieved for the placement of the panel 4, making the placement of the panel 4 accurate. In actual manufacturing, the upper surface of the panel 4 has a film, and markings 13 corresponding to a plurality of keyholes 3 are printed on the film. The panel 4 can be positioned through the installation groove 6 to make the markings 13 correspond to the key slots, making the fixed position of the panel 4 accurate. At the same time, since the depth of the installation groove 6 matches the thickness of the panel 4, after the panel 4 is fixedly arranged in the installation groove 6, the upper surface of the panel 4 will not protrude from the upper surface of the housing 1, making the whole more beautiful.

[0055] Example 3:

[0058] Among them, the outer diameter of the spring 5 in the round hole 8 matches the inner diameter of the round hole 8, and a guiding component for guiding the spring 5 is arranged in the special-shaped hole 7.

[0059] In this technical solution, the key holes 3 are divided into special-shaped holes 7 and round holes 8 according to the control categories, which is convenient for users to distinguish the control categories and is more beautiful at the same time. At the same time, the outer diameter of the spring 5 in the round hole 8 matches the inner diameter of the round hole 8, so that the round hole 8 plays a guiding effect on the spring 5 in the round hole 8, making the spring 5 in the round hole 8 not easy to swing and affect the touch effect.

[0060] Example 4:

[0061] This embodiment provides an air pump for a medical massager. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0064] A connecting plate 10, and the outer ring of the guiding sleeve 9 is fixedly connected to the hole wall of the special-shaped hole 7 through the connecting plate 10;

[0065] Among them, the spring 5 in the special-shaped hole 7 is located inside the guiding sleeve 9, and the outer diameter of the spring 5 in the special-shaped hole 7 matches the inner diameter of the guiding sleeve 9.

[0066] In this technical solution, by providing the connecting plate 10, it is convenient to fixedly arrange the guiding sleeve 9 at the middle position of the special-shaped hole 7;

[0067] Through this structural design, by providing the guiding sleeve 9 and the connecting plate 10, it is convenient to guide the spring 5 in the special-shaped hole 7. After the housing 1 is assembled, the spring 5 in the special-shaped hole 7 is located inside the guiding sleeve 9, and the outer diameter of the spring 5 in the special-shaped hole 7 matches the inner diameter of the guiding sleeve 9, which has the effect of preventing the spring 5 in the special-shaped hole 7 from swinging, making the spring 5 in the special-shaped hole 7 in good fit contact with the panel 4.

[0068] Meanwhile, the inner diameter of the guide sleeve 9 can also be conical, with its major diameter and minor diameter located at the lower and upper parts respectively. The major diameter is larger than the diameter of the spring 5, and the minor diameter matches the diameter of the spring 5. When the housing 1 is installed, the major diameter moves towards the spring 5, facilitating the entry of the spring 5 into the guide sleeve 9 through the major diameter, making the installation more convenient.
